Yep you have to feed the little bastards and it does kind of suck that we feed them for 2 weeks and then toss them out with every res change. I liked Carbo Load in the DWC I had not thought about it again because all the users on here back then poo-poo'ed on it. Maybe a little negative review goes to far. No molasses or anything near that viscosity  in the res thank you, I have cleaned up for the last time. Bud Candy is worth another look at too. Thanks
