anyone know....

how to stop this happening?

cheers

BUBBLES ?!? .. bubblesbubblesbubblesMAHBubbles !!

how long has it been like that ?

what additives have you got in there ? (PTN or PHN Nuke or dyes )

mine was still like that for a few days while the air bled out

Also .. have you cleaned the loop using a detergent ? you may not have fully cleaned it out after and now have a "washing machine"

haha!

thanks for the reply.

additives, i have feser anti corrosive, pt nuke, and feser uv dye (about 1/3 of a bottle).

this is in deionised water (which, from experience of using distilled and deionised this does it more so).

this is like it constantly. if i have it off over night, it'll reduce, but as soon as it's fired up i get a pink foam sitting on top of white foam. in the lower res, there isn't any dye (but pt nuke and anti corrosive) and it's substantially less.

the loop hasn't been cleaned, this has been like this since i put it together a few months ago..

EDIT: i forgot to mention, the other day i tried filling the res up a load more which helped a little bit, but after a few days it came back

okay additives may be mixing and causing this for sure, especially as the non additive loop seems better !

what you are experiencing there is the separation of dissimilar fluids

like a lava lamp... a green fluid that floats inside an orange one but they never properly mix

My only suggestion would be empty it, clean it and only use biocide in deionised water

thanks for the suggestion, but i'm not so sure, i mean, the dye is supposed to be used in this system, as are the other additives, and the only difference between the loops is the purple feser dye, so logically that *shouldn't* be happening with different chemicals in the loop together, as that is their intended use? feel free to correct me on that

anyway, you can't quite see it in the pic, but on the left side is where the inlet to the res's are.
the top one is using a ddc 10w pump, and the lower one is using a d5 vario on 1 or 2 speed setting and so is a lot slower...
my point being i think it's caused by the more powerful jet of water causing bubbles to form where there is the little 'hump' at the top and bottom of the res in the middle, causing turbulence.

i'm stripping down the loops as soon as my full cover block for my mobo arrives next week, so will give everything a good clean and see how it fairs without any additives in.

i was thinking of maybe rigging some sort of circuit to allow for speed control of the pump, but not sure if that is possible... i was under the impression the ddc had some sort of microprocessor control?

you only get foam where air is involved with turbulence I think...

there may be an air pocket in there or something like that ..

getting a bit past my experience now sorry

 

[twist3d0n3]

yeah there is a bit of air in there, i can't quite fill them right up as i have to rest them at a bit of an angle when filling. still, the bottom one has the same amount of air so technically is subjected to the same circumstances
