Nasty sludge building up in my res

What is this stuff? I noticed a bit of it last time I changed the res, but this time there is a ton. It's only been a week since I changed it, and I change it every week.

Here's everything I've ever put in there

GH grow, micro, bloom
koolbloom liquid and powder
floralicious bloom
sweet leaf
hydrogen peroxide


Anybody know what it is?

I don't know if this is your problem but you might want to check this thread:

Bottom line - the pH adjusters he was using was causing the problem.

also make sure that the nutes/additives work with h202 , it cancels out certain additives and nutrients....I use hydroguard to treat my water and you can not use with h2o2. I would maybe get away from the h2o2 for a bit and try something along the lines of hydroguard or some other water treatment additive. I have had luck with h2o2 in soil but in hydro I've never had much luck with it to be honest. Just what I would do...or rather what I did and everything seems fine now.

good point! might want to try using FloraShield (I use it) instead of the H2O2 - it is a G.H. product.

this looks like a canidate too, if you have airstones in the res. Thanks for this one, learned something new it's pretty good to know...yuck.
