Cloudy water after DIY CO2

I changed my substrate (Flourite,) filter, added some driftwood and new plants on 1/20/10. All has been good until I started my own CO2. I bought a red sea bio turbo system. The included mix never bubbled.

After lots of reading here and elsewhere, I use 1/8 tsp of yeast + 1/2 cup sugar + 1/2 tsp of nonfat dry milk in a 1L bottle. I let it sit unopened for the first 12 hrs. It started bubbling nicely in almost 24 hours.

No problems for 4 days until I knocked the dang bottle over last night and it spit a truckload of bubbles and muck into my tank. Horribly cloudy water ever since. I changed 40% of the water today. It cleared a little bit for 10 minutes. It's a mess again.

ph 8.5
nitrite 0.3
kh 7
gh 7
ammonia 0

I had my lights on for a few hours today.

What can I do?

I'm not an expert on what to do after this stuff gets in your tank but likely all you really can do is a lot of massive water changes until things clear up.

To avoid this happening in the future I would suggest putting a separator in between your yeast mix and your tank. All you need to do is run the tube from the mix into a second bottle and then another tube from that second bottle to your tank (the second tube to your tank should only enter the top of the bottle by an inch, the tube from your mix should go to near the bottom of the bottle). That way, if anything ever escapes your yeast mix bottle it will end up in the second "separator" bottle instead of your tank. I would do a search for "co2 separator" to get better instructions on setting it up. Also, if you add some water to the separator bottle (enough so that the tube from the mix is submerged) it can also serve as a handy bubble counter.

yeah do a big water change again and again. Id make something that will allow the co2 container not to fall, either a big piece of velcrow on the side of the container connecting it to the side of the fish tank stand
