because they are fancies they dont need the 20 gallon per fish so your fine, I wouldn't recommend such big water changes either.

well there are two different recommended stocking levels for fancies - either 20g for the first then 10g for every subsequent, or 10g for every fish. even if I go for the latter, I am completely and utterly fully-stocked. they produce such a bioload that it is necessary (and even recommended) to do such big water changes. as I have said before, 25% weekly is not enough for goldfish, unless you have one fancy in a 30g or something. also as I have said before, doing big water changes may upset tropical and marine set ups, but it will not upset a goldfish one. big water changes is preferred amongst expert goldfish keepers, because of how quickly the nitrates climb in goldfish tanks. if I did 25% weekly, I would never lower the nitrates enough.

We have 4 fancies in a 40 gallon and only do 25% weekly but then we do have a bigger filter so maybe thats why we dont have any nitrate issues.

Its actually my sons tank, he does weekly water changes of 20-25% and the nitrates are never over 20ppm. He has a Fluval 205 external filter, there's also 2 baby bristlenose babies in the tank with them and an apple snail. He does have a whole load of java ferns in the tank with them too which no doubt helps too.

ohh I reckon it's all those java ferns that are keeping the nitrates down then. unfortunately I have no real plants in my tank to help me with this, so I just have to remove and keep in check the nitrates manually.
