I recently built an evap tower using a 5 gallon bucket and 4" pvc pipe....about 5 feet tall. Temps are great, about 25c full load. Problem is, my cooling loop is getting dirty, I can actually see dust/debris clining to the inside of my lines. I don't think I have a bio-funk problem as I'm using tap water and add about a gallon of fresh each day. I think it's just a normal collection of dust and crap from the air.

First thing I'm doing is adding a fan filter, and I've flushed the loop with several bucket loads of fresh water. Unfortunately I still have a lot of funk clinging to the inside of my lines and I'm sure to the insides of my blocks.

Is there any type of chemical I can use to flush the system? Particulary anything that is safe for my pumps (ViaAqua 1300's) and blocks (swifty cpu and gpu). I'm not particularly in the mood to tear the whole thing down, take apart the blocks and clean it all up. I will if I have to, but its only been running about a month and I was hoping there was some way I could flush it some how.

Any ideas??

Thanks!
