Hi guys, I recently stralized my dwc bubblers with ho2o (oxy plus) at twice the recommended dosage as they were empty...I waited 24hours and then added my nutes/plants etc..everything looks good and the water is clear but I've got a build up of creamy white/cream coloured slime..it doesn't smell and I'm sure it's a reaction between the nutes and ho20 or something :-/ just wondering if anyone else has had this and what the outcome was..the ppm has dropped and the new girls that are in there aren't out of the net pots yet so I couldn't say how the roots look but above the pebbles the look cool..anyways would appreciate any input :))

Question number one is: Is your resevoir light proof? Some tubs are opaque but still allow a small amount of light to penetrate. Removing the light goes a long way to removing algae and other growth.

Yeah it's light proof..I really don't think this is a bacterial growth..it's def a side affect of the hydrogen peroxide..it's a the same consistency as moisturiser..no smell..temp is 25..ph holding steady..I personally think the high levels of ho2o "reacted" with the nutrient and solidified it as a white chalk which is a goo when when wet..but that's just my best guess....

I've seen this sludge you speak of around the hose from my dehumidifier. Your water obviously has some nasties in it. I'd suggest bleach. There are some threads on this site about how to use bleach correctly in your hydro system.
