My new tank is almost cycled, it seems, and will be ready for its first "nearly cycled" water change soon. My question is this: I'm using the Prime conditioner well reputed on this forum. Should I let that new treated water sit out in a bucket for a full day before doing the water change? I don't want to upset my good bacteria that has grown.
Currently the ammonia is at .25, nitrites 0, nitrates 10 to 20
with temp at 80. The inhabitants are five harlequin rasboras.
I know a water change will help bring ammonia to 0, and I'll watch it from there. Prime will certainly take the ammonia to 0, but I don't want it to zero out those nitrates.
I was thinking of a 20 % water change to keep from overwhelming the good bacteria?
Thoughts, please. Thanks. This is my first time to do this, so take it easy on the newbie!
