Yeast in tank :,(

[Andrew.]

Well, I was on my second DIY CO2 bottle and yeah ... some yeast got in there.

My first bottle went completely fine, nothing bad happened, plants did extremely well.

The second bottle, which I created yesterday, foamed up overnight. The water is cloudy at the moment. I did a 30% water changed and rinsed off the filter pad. I don't think that too much went in there. I did a search and read the posts about the entire bottle or half the bottle going in there.

My fish are still alive as well. How often should I do water changes to clear this up? People in the other threads said keep doing 50% water changes, but mine isn't on a scale that large. How much and how often should I do to clera this up?

Yes, I should have had the second bottle to catch this stuff, but it was fine the first time.

Thanks.

Huh, never had this problem. Haven't seen anything to suggest this is catastrophic either. You seem to be doing the necessary changes, so I'd go by appearance and smell to make sure things are getting cleared up. "The solution is dilution" as they say.

By the way, I don't think most folks have a second bottle, so don't feel so bad. I'm wondering if a check valve would have reduced the impact a little though?

The water smells normal. I had a check valve. It has some of the gunk on it too so I through it out.

Sorry to hear of your mishap. I've got two 2-liters going in my 29 also and have feared mishaps but luckily haven't had any. I agree with geofield, just keep doing water changes every day or other day until the water is clear again.

Your fish should be fine, that happened in my tank too. The fish didn't even notice. Just keep doing pwc until its clear. I just did a couple *large* water changes, like 75 percent, it was fine.

I agree - a large PWC or two will probably do it. Check the plants and be sure they aren't slime coated - a good tapwater rinse followed by an aquarium water dip should fix it if they are.

The water cleared up pretty good last night. I rinsed off the filter pad before going to sleep. This morning, the water was crystal clear. I rinsed off the pad again and did a 25% water change just in case. It looks back to normal at the moment. I don't see any slime or anything either. Thanks guys.

A check valve only works one way. It is likely that your check valve would be intended to avoid a siphon FROM the tank and not something entering the tank. Otherwise, you would never have injected any CO2 into your tank as the check valve would not allow "downstream" flow.

The "must" from your DIY CO2 system could have varying degrees of toxicity. A product of fermentation is ethyl alcohol which is not likely to be good for fish. The level of the alcohol depends on how long the fermentation process has been underway. I would suggest that you continue to do fairly large daily W/C's and keep a real close eye on your fish particularly sensitive fish such as fish with skin (loaches etc,) angels, etc. If you see some distress increase the water changes and clean part of your filter regularly. However, be careful not to crash your bio-filter.

Not necessarily true. A lot of reefers use vodka in their tanks to introduce an algae bloom to lower nitrates.
