Hi all, been cycling a 230l tank over the last 5 weeks. I have been dosing ammonia to 4ppm. The nitrite and ammonia are now dropping to 0 in a few hours. My question is when I stock fish I will obviously do it gradually however will the bacteria start dying off as the fish load I put in wont be dosing to 4ppm anymore. I was going to start by adding around 10 of my Cory's into the tank wait a week or two then add bosmani rainbows over. Should I add a bigger biomass at first or do it gradual like I'm planning? Sorry for the noob question it's been about 6 years since I cycled my last tank.
