Re: Why am I changing so much water?
Well, I, for one, have not done a water change on any of my three tanks (a
ten gallon gf, with a whisper 3, a 25 gal community, with a emperor(the
smaller model) and a 45 gal tank with 2 oscars, which has an aq300 and a
fluval 203). They all stay at nil in the ammonia dept, and my fish are all
going swimingly. I do do top offs, which replenish trace elements, whenever
evaporation has lowered the water level too much.
So, why do we change water? Well, in the beginning, getting a tank started,
I think that it is more important, to help control ammonia spikes, algea,
etc., however I really can't warrent it with my tanks.
