Hi my latest water test results
Nitrate 0
Nitrite 20
Ammonia. 0.25
High PH 8.0
PH 7.6
I use seachem prime on water changes,should I do 15% water changes once a week to get the ammonia down to zero or more four fish are still flashing ?,I have 5 pearl danios 4 zebra danios and Four Venezuelan black corydoras in a 85 gallen tank,I was giving the four zebra danios as my friend was going to get rid off them so I know I'm a little over stocked,some advice would be appreciated thanks
