Hi everyone! Please help. I tried to set up a CO2 thing last night which never ended up working right and when i got home from work today my tank is completely cloudy. I'm not 100% sure it's algae but it makes sence and everythign in the tank is slimey. I just did a 50% water change because I freaked when I couldn't see any of my babies. I don't know if everyone is even still alive!!!! Help..how do I clear the water without putting chemicals in the tank? I already have 2 filters running.
