I have 2 baby fish in a tank that is still cycling I’m trying to get their ph levels to match my tank that is already cycled at 7.2ph. My baby fish started out at ph 6.0 today so I got my gravel cleaner out and got the waste out and ended up taking out most of my water so I filled my water back up and put stress coat and quick start in the tank and I also added ph increase and it brought the ph up to 7.6. I don’t want my fish going into ph shock and I have no clue what to do to fix this. Please help! how much can you change the ph and how often can you without the fish going into ph shock?
