algae?

new build, only about a month old.

coolant is distilled water, about 1L, and 4 drops pt nuke phn (benzalkonium chloride).

i'm seeing some green stuff in my blocks, quite a bit actually near the bottom of the cpu block. how can this be after only 1 month?

well i'll need to drain the loop and scrub everything? maybe i'll dump in a lot more pt nuke phn first.

Yea, that looks like algae. Consider Mayhems biocide and inhibitor. Definitely scrub the **** out of that loop and use high temperature water.

argh... yea i'll try mayhem's next.


minimizing additional growth might be good enough for me as a temporary measure. i just added 12 more drops of phn. maybe if i let the loop get really hot (60-70C) that can sterilize things.

Pretty weird to have growth that quick.
What are you using coolant wise? Have you got biocide or a killcoil?
I have been using distilled water and kill coil for last 8 years and no corrosion.

I like to have fun.

I had a bad experiance with algae once a long time ago, due to over diluting the coolant.

It can VERY quickly clog the loop for very bad consequences. I suggest dealing with it right away.

i know i should but i'm feeling hesitant to take apart the loop because some of the fittings are quite tight and difficult to reach.


yesterday i ran p95 and furmark simultaneously, turned down the fans, and got the water temp up to 60C for about an hour. maybe that sterilizes things . also added a lot more PHN. i'll monitor it for maybe another week and see what happens. if it doesn't get worse, i might just leave it as is and clean it in the future when i change or upgrade parts

You know most watercool component start degrading around 60c water temperature ? Apparently not
Demount all clean and use a premix liquid before doing more damage
My 2 cent

yea 50-60c is top end side of almost all res and water blocks can cause cracks doing that and have a dead computer from leaks all over everything.

I agree. Just because it is small and green isn't conclusive that it is algae. Distilled water user here too.

Possibly, it could be junk from your radiator. They are quite difficult to clean 100% due to the nature of the construction. That being said, I've only had "black" junk from my radiators. Never green.
