Jebao DP-4 Dosing Pump

[@johnsreef2622]

Very Cool. When I get to this point I will insure calibration. Like the jars. good find. I would not have thought to use them because of metal tops. You are always teaching. Thanks again👍

[@cyberaquarist]

Thanks John! Don't worry about the metal tops on the jars. They won't be coming in contact with salt water, and the calcium and alkalinity supplements won't corrode them either. I appreciate the comment.

[@MereReef]

You have no idea how helpful this was thank you so much man 🙏🏽

[@cyberaquarist]

MereReef You are welcome

[@shoz2502]

I almost binned this doser.. your video helped me calibrate the doser properly.. Excellent Thanks

[@cyberaquarist]

shoz ney You're welcome and thanks for watching.

[@shoz2502]

cyberaquarist I wonder if you can Tell me the correct calibration to get 0.75 if possible. ? thanks cyber

[@chadcleland2864]

Thanks for the great info. I have one coming in soon and did hear about the calibration issue from my LFS. This will make setup much easier. Thanks

[@cyberaquarist]

Thanks for the comment Chad. I'm glad that I tested the first dose's accuracy. Otherwise I could have crashed both of my tanks. For the price these are great dosing pumps, and the calibration issue is easily solved.

[@mattbourque8291]

This was one of my first buys and I also use one of the channels to ATO using a common 5 gal jug. Works for me...

[@briansfishtanks]

Great info bud! Glad you caught the calibration issue. Between you and I there could have been 3 tank crashes

[@cyberaquarist]

Thanks bud! One other person said that his LFS told him about the calibration issue. Thanks for all your help with this project.

[@RogueAquariums]

nicely done video bro. very informative. good thing you were able to catch that calibration issue before you started dosing or that could have wreaked havoc in your tank. for the money I feel Jebao is a very good product and reliable. 👍keep up the great work!

[@cyberaquarist]

Thanks bro! Other than the calibration issue, these are working very well. I'm happy with my decision in going with the Jebaos over the much higher priced dosing pumps. Thanks for the kind words and the support.

[@RogueAquariums]

+cyberaquarist I agree. anytime. :)

[@abdullah5970]

Very helpful my friend. I love your explanation, is on point. I just ordered one for my 100g reef tank.

[@cyberaquarist]

abdullah ahmed Thanks for the positive feedback. I'm extremely satisfied with the dosing pumps. Makes dosing easy. Remember that these aren't "set and forget". You still have to test parameters and adjust accordingly. I test once a week. I had to program an extra dose for my alkalinity additive on my 25 gallon just this week. It had dropped to 8.3 dkh due to the extra coral growth. I like to keep it at 8.9 dkh. Good luck!

[@abdullah5970]

cyberaquarist absolutely! I just like the fact that it's easier to use and it will also dose on time and at certain time as well everyday. Better than by hand.

[@akatonyh]

This was a super NICE & GREAT clean vid :)

[@PaulBlaney]

just found your channel. i'm subbed :) i love my jebao pump. great idea to solve a great catch man wow nice to know the jebao ain't right ..

[@ScottM]

great video and I am thinking about getting this doser and your video was very helpful. Thank you

[@kg2nc]

That's great that you found this calibration issue. Like you said it could of been catastrophic.

[@cyberaquarist]

Thanks for the comment bro.

[@jong9970]

Wow! Thanks for sharing. I'm looking into getting this dosing pumps. Saved for future viewing reference.

[@cyberaquarist]

Thanks for watching. I believe this dosing pump is a great value. The calibration flaw is solvable, so that really isn't a problem. Let me know if you experience the same problem when you get it.

[@CJSAQUARIUMS]

Good catch on the calibration issue.. You should write a instruction booklet and sell them to anyone with these pumps and have jabeo pay you smh. What are your top 3 salt brands to use that will not throw off your dosing regime? I'm looking to change from reef crystals after this bucket to shoot for more natural sea water parameters ... RC makes it impossible with the frequency of water changes I am looking to do.. Just curious on your top 3 ... Thanks

[@cyberaquarist]

I'm just glad that I caught the issue before I crashed both of my tanks. As you are well aware, we have to check, test, and question everything in this hobby for quality assurance. I'm currently using Aquavitro Salinity for my salt mix, and I've had great results with avoiding large swings after a water change. I didn't really base my tanks dosing regimen based on coral uptake, but rather my tanks trend. I averaged out uptake and removal over a 45 day period to determined my daily dose. My top three salt mixes are 1. HW Marinemix Reefer, 2. Aquavitro Salinity, and 3. Tropic Marin Pro Reef. All of these salt mixes have been formulated with optimum levels of the essential elements and major and minor trace elements for reef tanks. They are also some of the purest / cleanest salts on the market. Reef Crystals is pretty good too. I wouldn't hesitate using it. Thanks for watching and collaborating. I always enjoy and appreciate your input.

[@shanemoore7339]

I use the HW Marinemix Reefer and the 3 corals I have seem to perk up after my water change like crazy. My shrimp constantly molts as well and is growing like crazy. The only thing that worries me about this salt is I have been getting a little lower than advertised for ALK(less than 7). I'm wondering if this is why I am getting some blackish green hair algae even though nitrates and phosphates are undetectable. Calcium is consistently at 425-450 and Magnesium is always 1350(measured with Red Sea test kit).The other thing that sucks about this salt is that I can only find it at one supplier(bulk reef supply). It is easy to work with though. You can mix it with room temp water and damn near stir it clear in the mixing jug with a stirring stick. Great video cyber. Maybe I will switch to Salinity as well since I can get it at the LFS near me. The owner changes 10% of his 200 gallon show tank every 5 days, never doses and his corals are exploding! I swear, there are a million different ways to do this hobby!

[@cyberaquarist]

+Shane Moore Thanks for the comment Shane. HW Marinemix Reefer is an extremely high quality salt mix that has been around forever. Each batch of Aquavitro Salinity is labeled with the test results by an independent lab separate from Seachem to insure quality and validate elemental makeup. My own tests parallel with the lab results. If you decide to switch to Salinity I know that you will be satisfied.

[@Skeptic2006]

I have a DP-4 and then some of those peristaltic pumps that I bought before. I wonder if there us away to add them whitout buying their slave unit.

[@EddiesReefAquaria]

Hi my friend I'm planning on my upcoming project to incorporate a dosing pump system also so as to keep my parameters in check.

[@cyberaquarist]

An upcoming project? Great! I'm looking forward to seeing that. Keep us posted.

[@EddiesReefAquaria]

Will do, Again many thanks for you and others for watching my videos and subscribing to my channel. Eddie

[@piranhakeeping3860]

I have issues with air getting into the lines at the output and the input. It also seems to back siphon the liquid back down the tube sometimes.

[@NYCityCichlids]

Great job on this video.

[@cyberaquarist]

Thanks bro

[@Deon0026yickadee]

How long should you wait to dose. ... I have this same lagoon cycling now. When can I add this pump and dose my friend? “When did you decide to dose?” .. looking to add some Lps and Sps and would like to start them off right on track

[@StNovaSt]

Hey man. I realized and did this but you know what happens on mine? It shifts after a few days. So i setup for 1ml and its spot on today but a few days later its a at 0.7. Any ideas?

[@DJ_LittlePea]

That looks like some technical stuff right there 🤗🤗

[@cyberaquarist]

Haha! It's not as technical as it seems. I try to keep things as simple as possible, but I needed to automate my daily dosing. I manually dosed for 2 1/2 years, so I wanted to free myself of that mundane task. Thanks for watching PB! 🤓

[@haithamkittana5411]

do you still have this doser? Is it still working properly? have you faced any problems within a year of using? Do you recommend this pump to other? I am asking because chinese product normally not trusted and i need to buy doser

[@rsucre]

Cyberaquarist, do you know if you got the DP4 v1 or v2? I ordered one today and it states it is v2. I wonder if they fixed the issue. Definitely, I will have to check everything before it goes in "production".

[@Ambrosius13]

Thank you for the find on the calibration issue. What I did to fix the issue is to calibrated to 85 ml instead of 100 ml. Then I ran a program to dispense 20 ml and it was spot on. It wad approximately 155 revolutions for me to get it calibrated properly.

[@cyberaquarist]

Before I made this video I hadn't heard of anyone else experiencing the calibration problem other than Brian, but I knew it would be common. I'm glad that you corrected yours.

[@pdiehm]

i am using this pump. I'm getting a ton of air in my output line, even with a check valve near the exit point. Ideas?

[@cyberaquarist]

Paul Diehm make sure that the hoses are pushed all the way onto the hose barbs and that the connections are tight. After that, purge all the air from the lines by running a manual dose into a small container that you can pour back into your dosing reservoir. You don’t want the manual dose going into the aquarium, or it will raise your levels too high. Don’t stop the manual dose until you are certain that all the air is purged. You will get liquid coming out for a bit followed by air, liquid, air, etc. Once you have a steady steam of liquid you are done.

[@Skeptic2006]

Also I am interested if this device could be hacked for wifi control with an esp8266 or some such wifi microcontroller.

[@PaulsPlantedAquariums]

We had an aquarium club swap meet this weekend and I was able to get an awesome price one a pair of BRS dosers, I'm going to automate my daily two part PPS fertilizer dosing..

[@cyberaquarist]

Those are great dosing pumps. That was actually my first choice, but I couldn't justify spending the money for eight of them at $74.99 each and eight timers for @$9.00 each. It was more appealing to spend the $130 for two of these as opposed to $672+ for the BRS pumps. I know you will enjoy them.

[@bayareareefs8616]

Hey cyber how much carbon and phosguard do you have in your reactor, I have a 20 gallon tank and cant really understand how much to put in the reactor I have the I.M mini desktop reactor ,

[@cyberaquarist]

Hey bud. I have 17 total gallons of water in my Fusion 25 and I run 4" of carbon when measured from the bottom of the reactor. I place two of the circular sponges on the bottom, the carbon (Matrix carbon), another sponge, and then top it off with Phosguard (about 1/4 cup) and the fourth sponge on the very top. All brands of carbon release phosphates to some extent, so by placing it upstream from the Phosguard allows it to be removed before entering the display. This configuration keeps the media tight and doesn't allow any of it to tumble. This is what you want. It is easy to change out the Phosguard while leaving the carbon in. I change the Phosguard every two weeks maximum or when I start to see algae creeping up. I change the carbon about once a month.

[@bayareareefs8616]

+cyberaquarist hey thanks a lot cyber I'm new and your videos helped me out you and another guy CJ I think have the best aquarium help videos out on you tube so thanks again

[@cyberaquarist]

+Bay Area Reefs You're welcome, and thanks for the kind words.

[@joseCalderon1976]

Thanks for the video bud! I'm about to buy one of these for my tanks, but the newer version #2.

[@cyberaquarist]

You're welcome Jose. Hopefully the newer version won't have the calibration issue. I'm so glad that I went automated. Makes life so much easier. I test once a week to make sure all is well,. I had to up the Ca dosing on the 38 by an additional 0.5 ml a day after a few weeks of setup. All my parameters stay spot on. You'll really enjoy these dosing pumps. Good luck bud!

[@joseCalderon1976]

+cyberaquarist I just got it! It's interesting that some people say that this thing is accurate. I'll let you know how it goes. I don't know how to tell if it's version II though.

[@joseCalderon1976]

+cyberaquarist So yes I did run into the same issue. 100ML will dose 3ML instead of 2ML. I did try to set it at 50ML, but it dosed less than desired, so I just left it like that. Now I know that 1ML is actually 2ML. I'm also supposed to have the V2, but it looks exactly like yours.

[@bmorrison3665]

Fark installed mine yesterday! checking now.

[@cyberaquarist]

Let me know if you experience the same problem:

[@bmorrison3665]

THANK YOU! my tank jumped from 159pm to 183ppm over night. I have halved my dosing. that could have been really bad!

[@cyberaquarist]

+Byron Morrison You're welcome. Glad to have helped.

[@cyberaquarist]

+Byron Morrison You're welcome. Glad to have helped.

[@Steve-hm1sc]

Thanks for the follow info,I have had the same problems with a aqua medic evo 4 doser which is the same as the Jebao unit with the same firmware,it to has been dosing 2ml for a 1 ml dose! have calibrated to 50ml let's hope it fixes the problem ,Not good enough from aqua medic in my view.spread the word..

[@9StickNate]

How do you like this doser?

[@cyberaquarist]

9StickNate I'm glad that I started using these dosers on both of my tanks. They have worked flawlessly and keep my Ca and Alk parameters perfect. That's not to say that you can set one of these up and forget routine testing. As corals grow and their demands increase, the dosing will have to be increased as well. This is as simple as programming in the necessary amount of doses per day. I would recommend the Jebao DP-4 to anyone who needs to dose their reef tank.

[@ManCaveReef]

just got one. good video

[@NEMO20G]

Nice mate!! I may invest in one of these :)

[@cyberaquarist]

Thanks. It's definitely money well sent if you're dosing your tank. It saves a lot of time and effort.

[@NEMO20G]

cyberaquarist sound matey thanks :)

[@Eiooeek]

Digital time display for mine doesn't get precise after a period of time regularly, gotta reset again from time to time. Btw, personally got a DP-4 with a defective motor right out the box with no luck lol This brand doesn't have spare motor part available, but the only way to replace any defective motors, which's to send back where the vendor we bought from, and waiting to be sent back after unknow period of times... Lol

[@cyberaquarist]

Thanks for the tip on the clock. I'll keep an eye on that. Both of my pumps came with a spare pump. Maybe Jebao has just recently started adding that in.

[@Eiooeek]

+cyberaquarist My pleasure. But I think the "spare" pump is without motor in it, but anyway wish you to have good times with it, cheers mate :-)

[@icetek0713]

I had the same issue with mine. I bought 4 new motors. Before I got them a friend told me to remove the outer cover and spin the doser by hand. What do you know, that did the trick for all my pumps.

[@lunes-1]

👍

[@mckenzieelliott4932]

Almost killed my reef because i didn't double check haven't even been using my jebao but now that i found this I'm going to!

[@benoitlevesque9609]

gONNA HAVE TO USE THIS TO MANNAGE MY FERTILISER IN MY PLANTED TANK!!!

[@Ruffles206]

No more videos? Or you out the hobby

[@cyberaquarist]

Ruffles WRX STI I'm still in the hobby. It has been a part of my life for 36 years, and it always will be. I just haven't had the motivation to make another video just yet. Busy doing other things in life right now. Thank you for asking. By the way, the DP-4 is still working perfectly.
