A nearby health food store. I asked the employee at the local grow store and she pointed me in the right direction. I've heard something from a pool supply is a lot cheaper. I paid 15 for 1 quart of food grade, but I've heard the pool 50% stuff is only 20/gal (but I can't seem to find it anywhere).
I found some more white slime in my rez. It seems to start in the pump and eventually starts clogging it up. I'm using a decent amount of h202 (50ml of 35%) so I'm not understanding how this stuff can live. Can anyone identify what this is? I can try to get a pic next rez change, but it reminds me of clear/white snot basically. Any ideas? I tried cleaning my pump in h2o2 solution, maybe I need to soak it in bleach or something. I added 100ml (max recommended) tonight to see if it kills it, but we'll see. Suggestions appreciated & rep'd!
