grimey shit in the buckets and pump out box

filimey grime in the buckets and pump out box. what is it algea? is there a way to get rid of this or an easy way to remove it? lemme know thankss

also we washed the hydroton really good. why is it so murky and such>?
oh and my set up.


36- 5 gal buckets in two seperate 3x6 rows (same room)
running hydroton with Hydro farm nutes
air stone w/sub pump w/tubing etc
55 gallon res (filled to 40-45 gals)
2- 1000 lights 1- 1.5 feet above plants
all walls sealed with reflective white mylar.

heres where im at,

put in 12 lavender on 3/4/2010

so far on the aggressive growth stage of nutes (4th stage) about to move to flowering stage next week and move them to another room.

Clean the reservoir out good, and run the sub pumps in a warm water and peroxide solution, 2tbsp/5gallon water ratio, to thoroughly clean out the pumps, and make sure all your hoses and your reservoir are light-proof, to prevent algae build up...

sorry it's supposed to say 2tbsp peroxide/5gallon water ratio!

we are about todo a switch u think we could just wait and do it then or is it imperititve todo it now?

you could do it when you make the switch, it doesn't have to be immediately
