I haven’t had any filtration on it I’ve got a heater in it on 78 I don’t have a microscope but it’s very hard to see any active Infusoria with the naked eye like I could before I’ve had a light in it too try to keep the green water going I have a few plants in it as well I didn’t think it would ferment do you think that’s what’s going on and if so how would I keep something going that I can put fry in to raise up without messing up my parameters I need something long term I need something I can leave them in for the eggs to hatch because if I don’t get them out as soon as they hatch they fungus and die
