I recently purchased a 60 gallon from someone and they barley cleaned the tank. It had been running for two years. It had a ton of detritus build up in the sand. When I got it to my house and put it back together I think the sand got so knocked around it put the deities in the air and started breaking it down again. I’m noting what I believe is a severe bacteria bloom. I added Aqua Vitro Seed and Stability to the tank. Should I do a water change and remove the sand or just let it do it’s thing because of the beneficial bacteria that would be in the sand? Thanks for the help. Just wanna make sure the fish in the tank don’t die.
