Water change?

[jonas]

I Was wondering how much water do people change out for there water changes?

I have a 80 gal.I do about 15 gal, 20 when i think it needs a little extra.Is that to much or not enough?(scratch)

[coralreefer]

Does that include sump minus rocks? Sounds like too much depending how often you are doing it and how healthy your tank is, how much you feed and what you feed. The heavier you feed and more livestock, the bigger I would make the water change. Good rule of thumb is 5-10% weekly...many people don't do that much monthly...some never. 25% is too big a change unless you are fighting nitrates. Being consistent is the key.

I change 10 gallons per week(10 percent). If I am fighting nitrates add a mid week 5%-10%. I feed heavy and have an eel. I am considering going to 15% weekly if the nitrates rise again. Consistency is the key(Good replacement water helps too haha) ...

Water change whats that??? LOL... J/k. But in all seriousness I don't change water very often, I have a deep sand bed though.

I change 5 gallons every week in my 55 gallon tank. That works out to 12.5% because with all the rock and sand I only have 40 gallons in the tank. I am thinking about changing that though and doing a one gallon water change everyday which would be 17.5% weekly.

On my old 75 gallon setup I was changing about 15 gallons a week. It was about 85 gallons total. On my newer setup with the 120 gallon I have a 40 gallon refugium and a 20 gallon sump and I only change about 15-20 gallons per week.

I change 35 gallons every three weeks on my 180 gallon voume system, 5 gallons every two weeks on my 24 and 25 gallon systems and a gallon or so every other day on my 17 gallon frag system. Jeez, I just realized I spend far too much time doing aquarium maintenance...:>))

I change 10 gal on my 125 with 40 sump once a month, and 16oz on my 3 gal pico every 2 weeks

[Michael7979]

I change 25-30g every 2-3 weeks on my system which is about 275-300g total.

[defigart]

In my 60 gallon system, (40B and 20sump) I change about 1 gallon everyday. Yes honestly.

 

Any my skimmer still pulls out the nastiest stuff you can imagine. I wonder what those anemones are doing all night. LOL

40b, 20 sump, 20 fuge, 5 gallons a week change keeps it pristine.

[Gabe]

Maybe 100 to 110 gal. total volume. I change 10 gal. every 2 to 3 weeks.

[jonas]

Thanks to all of you for your input.I think i will do a 10 gal water change every 3 weeks.

We change 275 gallons every 2 weeks on the 1400 gallon system, 50 gallons every 2 weeks on our 340gallon systems and 50 gallons on the 120 gallon invert system ever 2 weeks. water changes are key in this hobby to keeping a successful reef tank. There are many ways to skirt around it but in the end a good water change fixes alot of problems that otherwise probably could have been avoided.

i check nitrates, when they get to an unfavorable level, or they start to rise, i change about twenty percent in my big tank, which is 130. and my biocube is so filled with live rock, that it seems like of i do a 5 gallon water change it is like 30% lol. my biocube is very densly packed so i do it more frequently with that one and it is so easy ti do a big water change that has good effect if all it takes is a five gallon bucket!

With a 20l I do 4 gal. a week but I have no skimmer on that tank.

[tigerv503]

It depends on the circumstances of your tank jonas. If your tank is stable and nitrate seems a little too high do a 20% water change. If all elements are totally out of parameters then you may have to do alot more.
