I come down stairs yesterday morning to find my DIY C02 bottle laying on its side...a little big but probably not more than 1/2 a cup of the mixture expelled into the tank. Anyways, i did a 50 % water change and hoped everything would be ok. I come home from work today only to find the tank SUPER cloudy and theres this white slimmy crap growing on EVERYTYHING!!! HELP!! What do i do? It doesnt seem to be affecting the fish and my water parameters are still within range. If i take everything but the substrate out and scrub it well and change nearly all the water will it be enough???
