Algae - what to do?

Ok, so I've had an Asetek Waterchill system in my machine since August now and I've changed the water only once - when I moved to London in mid-October. Both times I've used an entire mini-bottle of that pink water wetter/anti-algae fluid which OcUK sells.

Yet I had a quick look inside my machine today and I was shocked to see that things are living in it! Ok, it's not mega in there, but there's still enough in my opinion to be problematic in a few months time. I'm not too worried about the pipes as they can be replaced - it's the waterblock and radiator which I'm worried about!

So is this stuff removeable? And how do I prevent it coming back this quickly next time?

Just for reference: I seem to remember needing about 300ml of deionised water to fill it up properly.

Thanks guys :)
 
I'd ditch all the tubing, take apart all waterblocks (carefully, and if possible) and give htem a thorough clean with some hardcore cleaning fliud, diluted. As for the rad, well that could be a problem. I'd probably connect up a pump to it underwater and just let it run through for half a day, clean water every hour or so. Maybe add a bit of bleach or something that would kill algae. And also don't forget to check out the pumpm they are usually easily to disasemmble.
 
were you dumb enough to use tap water?

you should be using de-ionised water with a corrosion inhibitor like water wetter. if your using normal tap water then you deserve for this to happen. :p

Nah, this is stuff that I bought from a garage (Tesco's petrol station!) as designed for car radiators...

And I mixed the water wetter in with the ratio given on the side of the bottle.

Gonna pull it all out maybe next weekend but I was planning on getting a GPU block so I'll prob time it all round then. Just ain't too keen on putting things like bleach in the system as I don't know what kind of effect it'll have on the pipes - can it corrode metal too? (I seriously have no idea!)
 
Don't use bleach. One good method is to submerge the pump and the return pipe into a bucket. Fill the bucket with hot water mixed with several of the pellets used to clean/sterilise babies' bottles. Use boiling water. Run the mixture through the entire system for several hours (obviously with the computer off and the blocks away from their cpu/gpu! You don't want boiling water heating those up!)

That should cleanse and sterilise the system. Then dismantle and drain completely. Re-fill with pure water - I use water from my reverse osmosis drinking water system mixed with Halfords Coolant Conditioner.
 
You don't have to de-algae car radiators, right?

Just for the hell of it, as I never bothered bin the last bottle of water I used (as I still had some left), I had a look in the bottle to see if any of that magical green stuff was there. And no, there wasn't. So why's it in my computer instead? Is it because it's warm?

And no, when I'm gonna fill it up again I'm not gonna use that 'old' water :)
Also, how am I going to stop it coming back like this again? Use double the amount of water wetter?

That's the method I used to clean my system previously, has now been running for around 8 months or more & still no growth in the water.
My de-ionised water contains water wetter & UV Green dye.
So I think the cleaning was successful. ;)

anitfreeze is not really necessary in pc water cooling since all it does is alter the characteristics of water to have a higher boiling point and a lower freezing point.
water wetter is the best stuff to use since it helps to break down the surface tension of water and provide corrosion protection.

always use de-ionised water in pc cooling never use tap water since deionised water will not leave behind residue such as limescale etc.
