So I JUST started using molasses in my hydro setup a week ago, and I lifted up my res top to find, to my horror, a layer of mold floating on top of the water. Come to think of it, it's not that fuckin surprising to think that this could happen to a 70 gallon cup of sugar water sitting at room temperature. How the hell do people avoid this with carb sources in hydro res's? I didn't use H202, which I guess was dumb... right now I'm draining the res as much as I can (It's impossible to get the last inch of water out with the way it's configured... Then I'm thinking I'm gonna put a shitload of H202 in with the remaining mold water, pump it out, filll it up again... and repeat. Should I nuke the res tank with some bleach, even though I won't be able to drain it all out? Fuck, I could really use some advice here.

I have very limited access as far as reaching into the res because it's under a flood table with not much clearance... and with 24 otherwise perfect girls in week 6 of flower on the flood table I can't really move that either. The pic below shows the res drained out as much as I can, and as you can see their is a ton of gunk (mold) that I can't even really physically scoop out. FUCK FUCK FUCK HELP BUD LUV HELP BUD LUV! LOL.
