I am trying to cycle a new 29G tank with a single fish in it, and Nitrite spikes to 2ppm every night. This is expected. So I did large water changes with chlorine-treated and temperature-matched tap water, but the incoming water always makes the fish act like he is dying, for hours. The only way I can get him to stop laying half dead and gasping is by using water drained from my established 120G for a large WC in the 29G. but this is very cumbersome and not a daily task type effort, I simply can't keep it up.
The tapwater TDS here is so low that no pH measurements are reliable. My digital pH probe swings wildly between 7.5-8.0.
My tap water is around 10-20ppm TDS, so there's basically nothing in it. For the 120G I have crushed coral in the sump plus I add a small dose of Equilibrium for GH, and my water changes are smaller only 10-15% but frequent.
So I tried amending water for the 29G by adding to my treatment reservoir both: some GH minerals and KH (crushed coral). Also the usual dechlorinator. I let it sit for an hour, but then the pH in the reservoir read very high >8.0 so I was afraid to use it for fear of shocking the fish.
I have tested the tap for N compounds and found only the typical 0.25 ammonia reading I always do. going nuts here trying to figure out what I should do for this guy.
