So I bought a 75g tank about a month ago but did not have time to set up it.
So two days ago I am set it up as a bare bottom tank. So I removed all the gravel from the 75g and added water.
I had a penguin 330 that was on my 125g that I replaced about a week ago with another filter. So this filter sat out for about one and half weeks.
I just recently bought another tank with a penguin 350 that I took off. Only it was filthy, so I removed the carbon and intensely scrubbed the inside out and rinsed the bio wheels and put this on the 75g.
So the tank has been running for two days with a scrubbed out penguin 350 and a penguin 330 that sat for two weeks.
I checked my water params today out of curiosity and they read perfect
zeros across the board.
I checked it again thinking something went wrong and it was perfect again.
I forget what kit I am using but it is the master kit liquid test.
Think its ok to add fish?

There is nothing to feed the bactria therefore no bacteria to read
, and hope you haven't poisoned the water too much.
