I never thought this would happen....I tried to make a DIY CO2 generator for my 20G, but the pressure built up super fast an the yeast got into my tank.
I should have planned this...
Anyways, the water was very murky for the first two days (last weeked), but it's cleared up now. Then, a whitish foam appeared at the surface of the water. I did daily 50% water changes to combat this foam, but it just kept growing back. Finally, I do a 95-97% water change, waited a day, and the foam seemed to disappear.
Now we get to today. First, I filled the tank back up, then went to the petstore and bought 3 silver hatchetfish. I come back, and boom! the foam reappears. Considering I did a huge WC and I have an airstone in the tank, I don't think the yeast is harmful to my fish. It's been around 2-3 hours, and they seem fine.
So, how do I completely get rid of this foam? And, if I decide to make one of those CO2 generators again, how can I make sure the yeast doesn't go into the tank again? I've heard of the bottle method, but I'm not completely sure how it works.
.....In hindsight, I really didn't need CO2 since I have about 0.7 WPG....
