I had horrible nitrite spikes when the tank was first set up and I was trying to make it with the survivors. The nitrites haven't spiked during these two recent episodes.
We have accounted for any fish that died. In checking my chart, I *did* put in two new angle fish the day before. That was on the 14th regarding the spike was on the 15th. I've been buying RO
water from the store to do the water changes. Ammonia is present right out of our tap (as tested by API kits). Since I know I did so much wrong from the start - I haven't trusted our water. Always treat the RO
I certainly may be over feeding, but your questions did confirm my strongest concern that the tank may not be fully cycled yet. Drat!
Thank you saffikeagan. I think I'll wait until Christmas to consider adding another fish - or consider the joys of goldfish!
