I just switched my 29 gallon tank to plants. After a week of my plants doing fine, I decided to go with a DIY CO2 system. I think my problem was that i had the tube inside the bottle go the bottom (ie inside the sugar/yeast/water solution) After about half a day, the tank got pretty cloudy; I guess some of the solution went into the tank. I disconected the CO2 system from the tank, but the tank just got cloudier. It's now been about a day and a half: almost all the fish a re dead, I assume all the plants are dead, the tank is cloudy as ever. I have already changed about 20 gallons of water at this point, but the tank still looks like a wreck. At this point, I just want to start at the begining, with a clean tank. How do I get rid of this mess?
