danny boy said:its well known that 50% water changes or more are drastic measures only to be carried if you really have to.
redtailfool said:Not really. Discus keepers( breeders ) specially in the far east do 100% percent water changes or 50 twice daily to keep the water pristine. No cycling going on and no adverse effects either.

I always gravel vac the water i take out as well too so I do remove a big portion of waste. The 75gallon tank itself is only home to 1 archer, 2 monos, a black knife, pleco, an columbian shark, so i think its safe to say the waste load IS light.
guppy said:I liked seeing the mention of hormones Fried Fish. Some fish it does not effect but others like sunfish react to high hormone levels with stunting and early sexual maturity, that is why so many small ponds have huge populations of 3-4" sunnies. I like gravel vaccing every water change but I just do a surface vac and a partial(1/3) deep vac, it is a habit acquired from using UGFs.
