lots of sugar in your tank?

I run DIY CO2 in my 10g high tech tank, and last night i set up a new bottle. Something was wrong with the connection on the airstone, so no air was escaping.... and the airline tubing exploded off of the airstone, and the pressure pushed a whole bunch of my sugar/water/yeast mixture into my tank. the whole tank is really cloudy now, and i'm worried about my fish.

What effect does sugar have on your tank? I think sugars all have an empirical formula of about CH20 or C2H3O2, but what will that do to my plants and fish? I know if i leave it for too long, the yeast will produce alcohol and that will be deadly, but what about just sugar?

Glucose is C6H12O6, but is that normal sugar?

i would do some water changes. the sugar will become a food source for bacteria, and they will likely bloom. i'm not sure that live yeast will be a problem in the tank, its the mixture (their waste, alcohol, and sugar). check valves dont help this problem, put a secondary container between your generator container and the tank to keep this from happening.
eta: glucose is a simple sugar, and just about everything can use it for food source. most of the posts i've read with diy co2 tank contamination report that it screws the tank up pretty good.

I had the same thing happen to me, I could not see any deeper than 2" in my 33 gallon. I did a water change, approx 10 gal and set my outflow on my canister filter to agitate the surface more. I was operating a Bio wheel and a Magnum HOB. The water cleared up about a day or two later and I did not loose any fish or plants, lucky I guess.

As it was said already:
Do some big water changes in your tank.
then put a gas separator on your DIY system.

As everbody says, do a big water change. Then do another one. The longer it was in your bottle fermenting, the more dangerous it will be for your fish. Sugar and yeast are no problem, the alcohol they produced is what will kill your fish. After a day or two your water will be clear but you'll have a white film on everything. It wipes off easily enough from the glass, vaccuum what you can from the gravel.

well, like brendan said, a sort of white film developed, but instead of a film it sort of clumped up all over everything, almost like a blighted version of clado algae or bba, except its not. I did three 70% WC's on tuesday night which cleared it up for about a day, but my tank water is really cloudy again. should i continue WC's weekly or biweekly and allow it eventually sort itself out, or is there something more i can do?
