Great video, very helpful. My DP-5 came today and I found all 5 pump lines were pinched. Just in addition to the calibration part of this video, I calibrated all 5 pumps last night to 100ml was perfect every test dose. I unplugged the unit and then retested and found all 5 pump heads was off calibration by around 3-10ml. Had to recalibrate and then got near to ml set on unit, was around 2ml off after calibration so had to dose less on the unit to get 2ml more to equip was dose I need. Power outages - check calibration on your pumps! Happy reefing!

Amazing video. I appreciate your attention to detail. One of the best instructional videos I’ve seen in a really long time by far. Thank you so much. Just bought the two pump module by this manufacturer. Setting it up this weekend for 2 part dosing. Thanks again fir your guidance and problem solving tips!

[@jeremiex.mcleod3328]

Thanks for doing this! The fact that you're so detailed and comprehensive allows me to get an idea of what some of the program features are before I consider purchasing.

[@BlackV1000]

Absolutely great review and breakdown!!!! Nothing missed at all. Very impressed.

[@brighton09100]

Thanks for the video! I’ve been looking at this doser and your video makes me confident enough to buy it.

[@dz7385]

Thanks for your detailed video! I just got a DP-4 with WiFi. It wasn't dosing on the time I programmed it for and I didn't know why. Apparently I set the Interval time to 1 day, thinking that meant to dose every day. Thanks to your video, now I know that "1 day" means every other day. Whew! I thought I was going to need to return the item. Now I am very pleased with its performance and price value. Thanks!

You got my interest at drones and racing.. Interesting how hobbies are the same for different people.. multigp.. grgo chapter :)

Great video....got my doser yesterday and just couldnt get it to work correctly...your video just made my day....thanks!

[@jvntrs5989]

Best video of them all , thank you!

[@ProppedNutFPV]

I'm with you with the fp v drone thing. Freestyle for me... I got back into reef just to take a little break from flying. Thanks for the review.

[@jamescoleman7662]

Thank you, for this video. Walking through everything helped fix problems before they came up with kinks.. Great job!!

[@jamescoleman7662]

I followed the setup video and the front modification to move the dosing heads and it came out GREAT!! I did cut a clear piece of plexiglass to fit the new hole.

[@dwight992002]

Thank you for this video. I bought everything you recommended in this video.

[@janetting720]

Just want to say this is very helpful since the device instruction is not easy to understand. Two thumbs up. Good job!

[@yawarworld]

Great info! I really hope part 3 or 4 include how to test and measure your dosage.

[@eatsleepreef9565]

aliyawar that will be part 4 :) plus I have a vertical mod coming to. If you check out my Instagram you will see it. :)

[@gregtippins2755]

Good video Bro. I'm glad you made it because my dp-4 doser will be in Friday.

[@eatsleepreef9565]

Greg Tippins perfect timing :) glad you enjoyed it! Part 3 will be showing how to make DIY containers.

[@rankinwood2196]

great vid, just ordered me 1

[@donsmith7979]

Great job. I though it was crap, but with regular use , it should be ok. My tubes were stuck as you said and carefully removing/ installing freed up the little hose.

[@10474rcarlyle]

Great informative videos. thank you

[@stum4301]

Great vid.. just have a question my Jebao dosing pump doesn’t fill it up to100ml quick enough and cuts out at 250 rpm

[@chrissytipton4611]

GREAT VIDEO

[@kevaly19]

Really nice tutorial. I like your videos. Im just curious after calibration should remove the water from the tubes?

[@InappropriateReefer]

Great info man! I just did this. =)

[@eatsleepreef9565]

Inappropriate Reefer you did your before video or after?

[@eatsleepreef9565]

Inappropriate Reefer I'm thinking of making a vertical mod on it so it fits better and is easier to program. Check your IG for the pic

[@ReefCommunityWorldwide]

Make sure you all calibrate with individual elements, as they are thicker than water so may need more revolutions per 100ml.

[@norcoatomik1]

Good point , nobody mentions that ever tho I would have done that anyways , I see your point behind it haha

[@marcelrodriguez2067]

But doesnt it remove the calibration once you remove the silicone tube to place it on your tank? Since you dont wanna add the tap water thats hold up in the tube. Or do you put it in the tank with the water still on the tubes to not lose the calibration.

[@bradnadeau2789]

I had to fix the tubing upon arrival as well... but I cannot get the bottom part of the cap to snap on when reattaching... any suggestions?

[@justinstuart8382]

Could I possibly use this pump to does a water storage tank with prime by any chance? Thanks

[@paulballantine4614]

Very informative video. One question, do u prime the lines before calibration?

[@norcoatomik1]

Hahaha if it's so informative then why do you gota ask a question he answered in the video any wonder he dont comment back to yea or like ypur post lol

[@bencetoth2811]

Is it possible to program it this way: pump 1 runs on monday, pump 2 on tuesday, pump 1 wednesday, pump 2 thursday ... and so on? thx

[@Koloherides]

Do you need ph up and down solution or is it so accurate that it won’t pass the mark so up would never be needed

[@tomfasano9082]

Great videos! Question.. if I wanted to run this on a Tuesday and Saturday. Would I set 2 different times for the same pump both with 7 day intervals? And I am assuming that in order to get it to run on the day you want you have to actually do the programing on the day of the week you want correct? As in if I want it to run every Saturday at noon I would need to program it on a Saturday morning with a 7 day interval. Does this make sense? Lol

[@norcoatomik1]

No you smell like sh*t

[@MrBiggie30]

Hi there... I wanted to find out the inner diameter of the dosing tubes that come with the pump. Thanks

[@RobBoryckiGolf]

If this doser is good enough for you. It's good enough for me. Just bought the dp5

[@arturaugustynek670]

PS. I just ordered this too. With mag, Alk, and CA from Mecoral website

[@GregDuffySND]

Phenomenal video! Thank you thank you thank you for such a detailed instructional video! I have been looking into dosing and I was so overwhelmed hearing about measurements, how much to dose, etc., etc. You have eased my mind and I now cannot wait to get my doser. I will be buying the Jaebo. A few questions...does the doser come with the air line hose? Did you have to buy anything separately for the doser besides the holding containers?

[@BiminiDream]

Can air in a line slowly work itself out. If not what should I do?

[@BiminiDream]

Will air in the a slowly work itself out

[@piotrmroczek6587]

Hi noob question guys. If after calibrating all of them will connect new tubing for purpose of dosing I believe bubbles will come back and was wander how to make again hoses wet full of solutions ( or should I calibrate with solutions straight away)?

[@ezequielvalentin-crespo5730]

Thought I’d say it.. “That’s what she said” 😜 😂

[@AmazonasBiotop]

Thanks for confirming that the manual is wrong. That is the confusion... It says interval 01 as each day when it is like you said ever second day.. 00 is every day as you point out. The manual says "00 is no dosing"!

[@norcoatomik1]

What size tubing does the peristaltic pump use

[@circle4922]

Hi, Could I use this somehow to monitor/control and auto dose for hydroponics (pH, etc.)? Thanks.

[@norcoatomik1]

Yes you can , I wouldn t trust it for ph tho myself hahaha

[@lunes-1]

👍

[@davidrosario8874]

Hello Sir, my nephew has purchase the Jena with three dosing head, I was looking to purchase the same unit, but I came across a Jebao with four dosing pumps and Wi-Fi, so I was hoping if you can make a detailed video about that one. Thank you thank.

[@fagan316]

Can I set it to dose Monday Tuesday Wednesday Thursday and no dose Friday Saturday Sunday and how?

[@FlightTracker2]

Ordered one of these today, thanks for the heads up.

[@norcoatomik1]

I'll be using these for indoor fertigation on my marijuana plants , are these accurate after calibrating properly

[@Koloherides]

Blue light in grow room at night ?

[@niharikashetty713]

will the calibration (RPM) for the ml change with different length of the tube at the disposer?

[@eatsleepreef9565]

Niharika Shetty it kinda doesn’t matter because if it does change the doser will be consistent still. Even if it’s u see dosing it will be under dosing consistently. Not sure if that makes sense lol.

[@niharikashetty713]

EAT SLEEP Reef thank you so much! and also when I was calibrating with water to the 100ml, like you have showed in your video, I noticed that it after few RMP it didn't pump the water but the RMP kept moving ahead. I also released all the kinks in the tube prior to the use of the auto doser like you showed in your video. Where am I going wrong?

[@watergrunt3694]

Niharika Shetty, there could be air trapped in the dosing head unit stopping the fluid from making it to the rollers. Also, the length of tubing you use will not effect the calibration. The calibration is read/measured at the dosing head not the end of the tubing, you will just have a longer time purging the air from the longer line. I have had my DP-4 since 2013 and it still works great.

[@arturaugustynek670]

Does it reset if the power goes out?

[@umarkhalid7610]

im having a problem its running 250 max and i am having 70 ml only

Does anyone know what the comm port in the back is for??? Its like an ethernet port. Is this apex compatible!?!?!?!

[@briangoldstein3007]

Do you still have this doser? and is it still working? deciding between the DP4 and the GHL 2.1

[@eatsleepreef9565]

Brian Goldstein still have it with ZERO complaints. I would buy it again in a heart beat. Why pay more when it works great 😊

[@AzulSolido]

Does it matter at which height do you install the unit vs. at what height is the liquid container?

[@norcoatomik1]

No it dosnt matter at all just run it a km up the road you'll be fine hahahaha , does it matter if you run out of gas in a fucking airplane, hahahaha, hope that answered your question

[@scotty2salty327]

Can this unit dose smaller than 1ml increments? Or is 1ml the lowest amount it can dispense?

[@leehunt3234]

You have to dilute your supplements to dose below 1ml

[@Koloherides]

Round wheels. 3 of em

[@gazkershaw6156]

How do I dose 1.5ml

[@erman9647]

what steps would you go through in recalibrating the Jebao DP-4 ?

[@eatsleepreef9565]

ERMAN SMITH don’t quite understand? These are the steps for calibrating and recalibrating. So same steps if I understand correctly.

Can you Hook up 2 Jebao dp-4s to 1 Jebao dp-4?

[@thomasmccaffery5941]

I recommend using a scale instead of cylinder be more accurate.

[@yuyiboy]

Does it hold the program if you unplug it?

[@eatsleepreef9565]

yuyiboy yes it does. It has a battery inside that saves program and time when unplugged.

That’s great!! Thanks

Interval I see as skips... skip 00 skip 01 skip 02 days etc. Great video.

yuyiboy glad you enjoyed it :)

[@circle4922]

There's a lot of Reefer talk going on here. ...Get it?

[@joshgriga]

Actually there is a HUGE FLAW to this calibration process. Though everything else is sound, the process here does not account for the length of the tube and the distance the liquid needs to travel. Jump to 24:55 where the calibration revealed that 100ml = 185 RPM. That's only based on the distance traveled to the measuring cup he used. I'm pretty sure both his and your doser is further away from the tank being dosed. If that's the case, then 185 RPM will not push 100ml up that distance and into your tank. This calibration process then must take place from the install location in order for it to give you a more accurate result. This, I appreciated this video and I'm giving it a thumbs up.

[@gatoenfuego8734]

I know this is an old post, but felt worth mentioning the length of line is irrelevant if all of the lines are primed (as they should be) and just as important an RO check valve to keep the prime in those lines. If you stop and think about it for a minute, that should make sense.

[@tedfisher1396]

All the money we spen on livestock and corrals, this is not the doser to use. I was using one to dose calcium bicarbonate to raise ph in my fw 75. It would not hold calabration and would miss dose or not dose at all. Almost wiped out my tank, then stopped working all together. Its not easy to make adjustments to especially in a cramped stand. Not a well made product at all.
