ryanjury Posted February 12, 2008 Report Share Posted February 12, 2008 At a guess it will be because the KH in your water is low making your PH relatively unstable and fish their waste excess food etc tend to turn water acidic. If you want to keep your PH stable add some baking soda or something to raise the KH. Quote Link to comment Share on other sites More sharing options...
Caryl Posted February 12, 2008 Report Share Posted February 12, 2008 The fish are doing it We used to have 2 tanks identical in every way except one had guppies and the other had acaras. The guppy tank was always 7.0 but the acara tank dropped 6.5. More fish poo. Quote Link to comment Share on other sites More sharing options...
henward Posted February 12, 2008 Author Report Share Posted February 12, 2008 well thats fair enough - but the tank itself the water quality is good, no amonia in fact and etc. knife fish, aro, discus, jardinii, all say can live in 6 to 7.5 or slightly higher. but peferably 6 to 7 ph. it means thatthe ph isnt harming them... its jsut a bi product of poos and stuff.

Caryl Posted February 12, 2008 Report Share Posted February 12, 2008 I wonder if the hormones fish secrete add to it as well. Quote Link to comment Share on other sites More sharing options...
henward Posted February 12, 2008 Author Report Share Posted February 12, 2008 i was told by a discus breeder that the discuss slime itself is acidic and actually plays a part on making water scidic anyways, though i wouldnt even begin to take sides on that arguament... i have no idea but i know the fishes can thrive in these ph, but i was just curious the aro, knife fish, borneo tiger..(bar the two big ones) are certainly eating wiht no problems, healthy fish. any comments?
