Hey man, first thing to do is make sure, and I mean damn sure that no light is getting into your rez. Second, make sure your temps are staying in a good range, a little high is ok but not ideal. Third, the bubbley froth can be two things. It was/is probably the great white or possibly your "nitrogen supplement" as I know superthrive and GH stuff doesn't have wetting agents. It could also be caused by a rapid growth of bacteria in the rez. Or a combination of both. If you are getting nasty looking stuff in your rez and it is NOT smelling and it does NOT feel slimey, then it is the Great White benneficials collecting on your root system. I am not sure what color the great white is when you add it, but is it the same as what is growing in your rez? I have found it helpful when using any kind of bennie formula that adding some hygrozyme or similar enzyme product in helps feed the bennies so they can populate faster. This usually results in foam and nasty looking stuff on the root system for a few days, then it's gone and roots are clean except for pockets of the bennies that can be visible. I have uses Roots Organix Oregonizm XL and it is a black powder (due to the yucca in the mixture) this powder will clump and collect in my root system, right where I want it. My suggestion would be add in the great white but also put some hygrozyme in there to feed the bennies and give it a few days to settle or find it's own balance. It is like cycling a fish tank > if you have ever done so you know that you can't put fish in for at least a week while the bacteria cycles and the bennies overpopulate the baddies. Ok this is just my two cents let me know what solution you find works best. And by the way, I tried the h202 route and all it seemed to do was cause a whole different set of problems for me so I went back to using bennies and haven't looked back.
