- I assume you are adding minerals and trace elements to your tanks? I,
- too, went for 7 or 8 month without changing water (aside from what my
- protein skimmer pulled out, and evaporation replacement). Everything
- looked great, NOx, NH4, PO4, were all extremely low or zero. Yet, BAM!
- my creatures (especially the crustaceans) began to die. Apparently, they
- used up all the trace elements and were mineral starving.
-
- I do a daily water change now (one gallon per day; 58g setup). Not as
- much to control the pollution, but to replenish minerals and such that
- are in the salt mix. The entire process takes me 5-7 minuites a day.
- Not too much bother...I spent a hundred-fold longer just staring at the
- tank ;-)
