Hey, i think it should be said that if you misdose or something that one elements gets way to high, never remove it fast. The fast low to high and then fast back will more likely kill the corals then get slowly back down to normal. Always experiencd this with customers, never had problems if the overdosed element was removed slowly

A trick to avoid sucking a mouthful of water when starting a siphon is put the hose well deep into the tank, seal the dry end of the hose with your thumb and then lift most of the wet end out of the tank while lowering the dry end to start the siphon. No fuss. No mouthful of tank water. My grandfather taught me this for siphoning gas out of cars.

The % explanation is a great ADD to the hobby community. This was my number one conversation with in store-customers who were frustrated that their 20% water change did not make a significant impact to the 160ppms of Nitrates they were testing. A simple piece of paper and percentage break down would leave them with greater comprehension as to why a 20% water change was not the solution to see a significant impact in waste levels without proactively approaching the cause and effect and evaluating the equipment that was failing or missing entirely in consistent waste removal - most often a Protein Skimmer and a moderated feeding methodology.

[@koaleighhomestead2606]

I've taken my water changes to a whole new level, when I drilled my 125 gallon tank I drilled an extra hole in the back of the tank half way down specifically for water changes. I have a drain pipe inside the tank set at the desired level I want the water to drain down to with a sieve on top to prevent any fish, snails etc going down the pipe, this is painted black so it's almost invisible against the black background. The drain outside the tank then goes through the floor of the house and connects into the plumbing of the house. I have 2 taps on the plumbing on the outside of the tank, 1 drains the tank into the plumbing of the house, once the water gets to the preset level inside the tank it breaks the siphon which takes hardly no time at all. The other tap I connect a reef safe 1" braided hose to, the other end of the hose gets connected to the mixing station and I can fill the tank through the same drain pipe in the back of the tank, which also takes hardly not much time. Over all my water change takes less than half an hour, excluding cleaning the tank and mixing saltwater the previous day, and it just involves opening and closing taps, and connecting the filler hose to refill the tank. Eventually I'll run pvc from the mixing station, under the house, and to the tank so i can eliminate the need for the filler hose altogether.

I figured out #4 back when I had my 75g circa '04. Had a 2 story apartment, and I used the downstairs bathroom as a fish room. Bad water down the shower drain, and I had the new saltwater in a 55g bin in the same shower. A bit of kit bashing with the hoses, and I was able to refill the tank just by flipping a lever. That was such a huge time saver.

[@travertinepico751]

Great video, however i don’t 100% agree with the simple math of 10% 90%, if your doing a water swap (like auto water changes) and nothing else, then yeah it’s pretty much spot on. However, if you turkey baste the rocks, vacuum detritus from the sand bed, and change the filter socks that 10% water change will be potentially removing a lot more than 10% of the pollutants.

[@dontbetreadin4777]

Exactly! There's way more involved here than just changing water. I can get the same or better benefits from a 5-10% 'aggressive' water change as opposed to a typical 10-30+% water change that removes only water...... Also, I dont do water changes unless its an ABSOLUTE must. I've only done a 10% aggressive change once in 6 months.

[@ollywood6942]

Great video, but could have been so much better if you had done the countdown in the order that you do your water changes. 1) make up the water overnight... 2) check the parameters of the new water... 3) scrub/Remove algae 4) baste the rocks then onto the actual water change section... would have made way more sense (imo)

Great video, helps me as a beginner alot. What do you think about pre-mixing and storing Red Sea Reefer Coral Pro salt? I was thinking about premixing alot and i read in many forums that it's totally not recommended, but exactly as you say, if you have a busy time you might skip the change more often.....

[@BRStv]

Check out our BRStv Investigates Salt series. What we found is that as long as you keep stored with flow and heat, precipitation isn't an issue. That said, Red Sea doesn't recommend storing Coral Pro for longer than 4 hours, so just know that you may get different results than advertised if you stray from the manufacturer's recommendations.

[@seanharrington2908]

Nice!

[@djmjr77]

You can get these big blue 75 gallon storage containers with sealing open tops for 50 - 75 dollars. After years I just set up two, one for rodi and one to mix salt in. They are connected so I can open a valve to send rodi to the other one to mix the salt. Both have a tap to fill buckets.. after watching this vid, definitely gonna setup the retractable hose reals .. 6 5gal buckets for a 20% water change is a pain in the buttox!!!

[@simonhedderwick4516]

Not turning off the ATO when you're draining out the sump!! Done that a few times! 🤦‍♂️ I now have both ATO and Skimmer on a wifi socket and tell 'Alexa' to turn them off before I start my water change. Works for me.

Nice video, really love it :) I'm a bit skeptical for the part "Using a filtration before it goes to your aquarium" You will lose a lot of mineral and what not no? Some time I turn my light also when I know lot of corals will be expose for long, I splash them with my wet hand to make sure they don't dries

[@BRStv]

Keeping in mind that a sediment filter captures larger particles... the salt/calcium/carbonate/magnesium/trace elements are not large enough to get filtered out. It's those larger unknown and undissolved particles and impurities that we are concerned with removing via a sediment filter.

[@BRStv]

Any sediment in the water wouldn't be a trace element, so there shouldn't be any concerns there.

[@AquaSplendor]

@@BRStv Good to know, thank you

[@mattm9087]

I have my pumps lights and heater all on one power strip. Switch the power strip off and bam ready for a water change. Anything else you have that doesnt need to be turned off can be put on a different power strip and leave on. Side note: interesting about the algae bleaching. Kind of makes sense maybe thats what happened. Temp difference in room to water maybe threw them off too? Shocked them or room temp was too high/low? who knows. Anyway, I always turn the lights off simply because I don't like bright lights in my face while working on the tank lol, but nice to know it may be beneficial in some way too!

Lots of great tips! I ordered a bin from amazon last night on wheels that holds alot of water so I can premix it and just wheel it in to the tank but now think I will either get a pump or the phython and not even have to move it! Not sure if i can use the phyton into the bin though to take the water to the tank or is it the pump that would be best for that situation? I do have a big utility sink in the same room I am keeping the bin so I could drain it into there but cant fill it being its not fresh water. To bad I cant get full use out of it! I also thought about using my big cooler on wheels to drain water into and it has a plug you pull to release the water out. How would I change the alkalinity on a large water change? I dont dose being I do weekly water changes on my 10 gallon so now today I am doing my first change on my 36 gallon and I am going to do a 50 percent being it just finished cycling. Also when figuring percentage do you count sump as total water volume I suppose?

[@BRStv]

You'll need some sort of pump to pump your freshly mixed saltwater to your tank after you've drained it for a water change. If you need to adjust the alkalinity of your freshly mixed saltwater, we'd suggest using sodium bicarbonate. Unfortunately, you can't adjust it down, just up, so pick a salt mix that most closely matches your tank's water parameters.

I nearly killed myself with my first big water change last night and ended up flooding my sump! haha I couldnt figure out why when I got to the end of filling that it wouldnt fill!

It's certainly possible to have too good of a filtration system. Most reefers will monitor nitrate and phosphate levels to give them an idea of how their filtration is performing. The goal is low, but not zero, nitrates and phosphates.

[@johnatella8498]

If you have a septic tank, you don't want to be putting saltwater into it. There are many problems it can create by doing this. It is fine if you are pumping it into a local sewer but not a septic system.

[@leeverink32]

What i do is make my water in one 24 hour day. First i mix it with a aquarium pump and heater that makes the water the same temp as the tank. Then i measure the salinity for the last time both in the tank and the mix. Keep in mind that water does evaporate and the salinity goes up.(this is almost neglectable in 24 hours but to be sure do measure it) because salt cant evaporate from your water. To keep the water level correct first turn off any eqipment that cant run un submerged. (I dont run a refugium.) Then take out the water in the same container you use to fill that way you no how mutch to put back in. If you have any problems with your tank measure before the water change or your measurements will be incorrect. Wait at least 24 hours before measuring again to see any changes (keep in mind that it will always be lower with just added water and some can even be higher due to suplements in the salt.)

[@siggyincr7447]

"That water is absolutely full of decaying food, fish poop, decaying tissue" also, most reef tank's water is so pristine that using dechlorinated tap water to make your salt water would contaminate it.

[@bdawggification]

@@siggyincr7447 It’s not cleaner than most peoples tap water. Fish poop and dead animal tissue is as bad for us as let’s say phosphate and nitrates can be to your fish tank. If you drink fish tank water minus the salinity of course it’s gonna kill you.

[@siggyincr7447]

@@bdawggification We'll have to agree to disagree. The type of water that can support sustained SPS growth has next to no suspended fish waste. And I still maintain it's cleaner than tap water if you remove the salt. If it were had significant amounts of fish waste in it the nitrate and phosphate levels would rise in a matter of hours. But between the corals actively feeding on any suspended particles and protein skimming reef tank water is generally pristine. And no, drinking tank water would not kill you, though the salt will probably make you vomit.

[@bdawggification]

@@siggyincr7447 I bet you’d start agreeing with me if you actually were presented a glass of desalinated tank water with all the good fixings left. You don’t need to consume a significant amount of fish waste to get sick just like a tank just needs bit of tap water to be f’d up. Yes you will die, assuming you don’t stop drinking it after it making you sick or by ingesting the right pathogen that’s possibly present for your first (and last) time , which in a reef tank wouldn’t be all that hard.

Hey BRS.. after talking about using water changes to clean sand, remove algae and detritus you then go on to advocate automatic water changes which does none of the above. I think it would have been wise to encourage a regular sand/rock cleaning schedule along with auto water changes otherwise buildup of nutrients will continue to build up despite the auto water changes.

[@BRStv]

Just because you have an auto water change system doesn't mean that you can't ever do an occasional manual water change to help clean up the rock and sand :)

We've found that certain salt mixes can sit stagnant for longer periods of time than others (see our BRStv Investigates salt series). That said, if you didn't want to have to think about it, leaving the circulation pump on 24/7 is your safest bet. Doesn't have to be a huge pump by any means, just enough to keep the water moving.

Make yourself a seachem denitrate reactor using a 1 gallon water jug from the grocery store.. full it with denitrate and run a pump that flows 20-30gph and youre peoblem will be solved. My 135 gallon has 5 tangs a foxface and other various fish and i feed then heavily 2-3x a day. I use 2 gallone of denitrate on my tank making my own reactors with 1 gallon water jugs and some barb hose fittings and silicone. And running at 28gph my nitrates can go from 80ppm to 40ppm to 10 ppm in 4 days if i dont feed my fish. It really does work. Feeding my fish it keeps my nitrates around 20-30ppm. And without it ny nitrates would get to over 80 in just a week

I notice you guys say garden hoses are not safe but have a clip of someone using one. So what way is it?

[@ericn9175]

Really? How can someone “dislike” this video?

[@ryannguyen916]

they hate themselves for not having money for this hobby. haha

[@garrycole9187]

There is always some looser who never watched the video and just goes from video to video to push the dislike. They must have super busy schedules, LOL.

[@UnknownProductions0]

would running a heater in your storage bin be beneficial? maybe more specifically if you are running an AWC?

[@BRStv]

It can be beneficial with some salt mixes to avoid precipitation issues, but even with AWC systems, the room temp water being exchanged with your tank water usually won't cause that big of a change in your tank's overall water temp.

Where can you get the python detailer that there talking about.

My red sea coral pro salt says to only mix within a few hours of use I wish I could do it overnight.

[@drew-shourd]

Great video guys...but on #16, please understand that in natural coral reefs at low tides can leave corals high and dry for several hours....high tide is usually around 4pm and the sun is still very bright. I tend to think there was a different cause.

[@BoY860]

I use my return pump to return new salt mixed water to the tank with valves.

[@felix6571]

I would like to know how "auto water change" could be done. It could definitely save me some time and effort! My tank is established more than 2 years time, it looks really stable and good to me, and it makes me lazy to do the water change

[@BRStv]

Here's a couple of options we've done videos for! :) kzbin.info/www/bejne/o3yqkmVsl7JggpY kzbin.info/www/bejne/bHPIXnqqobZ9has

[@jeffmyers1051]

How about plugging your heaters back in I don't run a saltwater tank but a freshwater tank
