I had this happen during my last crop, but didnt put 2 and 2 together(4 hehe). I just added gravity to my current crop a few days ago, and after about 3 days, my reservoir was a brown, foamy, slimy, mess with a slight funny odor to it. H2o2 keeps it in check, if I add it at least every 2-3 days, but its nasty. And the same thing happpened last time around, and after I cleaned and changed the res, I didnt have a problem with it again...until now. Same thing. The gravity is the only thing that changed both times, and once it was removed, I didnt have another problem. Has this happened to anyone else? Is there a better way to combat it than H2o2?
Gravity hardener turns my reservoir into brown foamy nastiness

how about you dont use it anymore....
I probably wont use it next cycle to see if there is any difference since I am actually keeping this strain and to avoid the hassle. It really surprised me last cycle when I opened the reservoir to see ugly brown foam everywhere and it didnt make sense since my res was always clean and only ever got mild algae here and there on occasion. And same thing this time around. Clean for weeks. Even when I went out of town and my airstone came unhooked for 2 days, I didnt have a single problem with reservoir funk. But now I know, and knowing is half the battle!

Gravity and crystal burst will do that but
Snow ultra wont.
Air in the res from air stones are
The cause

I use FloraKleen at rez changes as this in an alternativce to H2O2 and seems to work for me, I run the 3 part GH flora series with Floricious plus,Liquid Koolbloom, and Cal/mg. Black light proof rez with stone aeration as well as it cycles water back into the rez through a nozzle I made with PVC fittings that also aerates that nute solution as well as keeps the solution in motion. Larger rez sizes also help with keeping solutions stable I"m using between 10 and 15 gallons for my flowering cabinet with 4 plants
Im running a 25 gallon tote for a reservoir. It is pretty dark, but not light proof, but it sits under my table and doesnt get much direct light anyway, but the runoff does. So far it has worked great. I need to get a cover for my table I think. Im using the complete Fox Farm line with solubles and have been happy so far in 2 cycles. I am also using Gravity, of course, used it in both cycles, but a trying a higher concentration this time though. I havent had hardly any ph or ppm stability issues with my setup. My setup only requires that I add water every few days, and a bump of nutes. Im running a disc air stone, and add H2o2 about every 3-5 days. Im using a 3x3 flood table that drips onto the lid of the tote, and then drips through holes in the lid. Check out the G13 x Haze grow in my sig for pics of the current setup. I need to update that though. Im 6 weeks into flowering now 
Since I posted this, it hasnt reoccured(it was handled in 36 hrs with the first H2o2), but its about time to add more.

First don't use h202 with anything organic!! I promise you you are doing nothing but bad by doing this!. And I say use this stuff very sparingly only a little at week 3 and again at week 6 at about half dose. It's a very concentrated nutrient... I also use h202 at every res change, just add your gravity about 3 days later as the h202 will evaporate.

k well on the bottle gravity/snow/whatever of the three even crystel burst say if foam starts or a out break of bactiria due to
adding, use H202 to clear it up

take everything hydro store people tell you with a grain of salt...
They are trying to push products.
