so i thoght id put this out there for anyone thinking about it,this is only what ive tested for myself and cant be sure about any other combinations.
i wanted to put an anti corrosive and biocide in my distilled WC setup which has the following mixture of metals,brass, copper, nickle plate.and was all ready to when i read on some forum that they can react.but it was 50/50 on opinions as some said it doesnt! so i decided to test it out before putting in my system.
i mixed distilled water with pulse moding biocide and feser base corrosion blocker and added some copper wire and brass fitting(didnt have anything nickle plated)for the first few days it looked fine and was starting to think its ok,but when i checked it today there are small green bits in the solution. so im glad i just put biocide in my setup.while it wasnt exactly carried out under laboratoty conditions,i did take care in setting it up and im happy not to mix at least those two together!
so anyone else have experiences with mixing additives? i just think its something to share, especially for newbies(like myself) to the watercooling world
 
I was just trying to do some research on Nickel and Copper, because I was trying to decided which metal I should go with for my components for my watercooling setup. I'm still undecided and don't understand all the benefits of choosing one over the other, however, I did read that copper produces a green film or small green bits as you are referring to when the copper constantly comes into contact with water. So this is where the green is coming from. As far as products to correct it, I am all ears I think biocide would probably do the trick but I'm not sure
 
Copper is best full stop. Nickle is a coating which will ware down over time even though people think it will last for ever. Water is a cutting agent and over time will ware down the nickle coating on a block were all are fins. this is normal ware and tear. Copper is bare on the water and will again ware down how ever you will not see it as its not "coated" copper.

So for a more stress free system copper is better over long periods.
 
How long are these 'long periods'? :)

I have a nickel CPU block which will be used with your Pastel coolant, and the system will be on 24/7.

well just water,biocide, copper and brass produced no green bits! when adding the corrosion blocker to the mix is when the green bits appeared.i appreciate what ur saying about copper though.

Well I know copper is the choice that a lot of household have used as piping for their water, at least I know in a lot of older homes did. I thought nickel was used like in rockets and space shuttles or in nuclear facilities because of it's resistance against corrosion.

I also read that it is not good at all to mix metals either

I hope Mayhems can provide a better answer for you regarding the green bits I think he should have a lot more knowledge about what is going on
 
Unless i know what is in the mix perfectly i cannot help. I would also need a sample and it costs up to £500 to test each sample properly.

well as for testing the sample,i think i can live with my own results rather than part with £500.
but i can tell you it was pure distilled water(from reputable company) pulse moding biocide(new and properly sealed bottle) and feser one anti corrosive blocker(new and properly sealed bottle),also about an inch of copper wire and a brass fitting.
i poured equal amounts of all liquids into the empty distilled water bottles x 2(one containing just biocide the other containing both biocide and corrosion blocker,100ml of water,1 drop of biocide and 5ml of feser one) sealed them up and just left them at room temp,shaking em up throughout the days.
only the one containing the mix of biocide and corrosion blocker produced green bits that ressembled fibres of cotten or dust or something (thats the best way i can discribe how it looked).
im actually not that bothered about finding out what this is or the reason for it,i was just putting it out there that my personal experience of mixing the two stated additives resulted in some sort of reaction causing green bits.so its just a warning for anyone who is going to use these products.
im quite happy with how my setup is and glad i never mixed additives(i may come to regret it in the future:)) as for corrosion only time will tell now
 
Ethylene glycol (poison) feser + Copper sulfate = they do not mix well together and should not be mixed.

I still do not know what inhibitor or biocide they are using in there mixes as neither of them tell you properly . Again with out really testing you (or me) will be second guessing. Im for one am not willing to pay to test other people products how ever you should never mix thouse two products anyway.

Mixing chemicals is dangerous especially when mixing poisons you do this at you own risk. -> http://www.tfc-us.com/MSDS/MSDS-FB.pdf
 
as mick says - mixing copper sulfate (biocide) with other unknown ingredients is a recipe for a reaction - the green will be the copper from the biocide dropping out of suspension

did you use feser one? or feser corrosion blocker?

the first one is a premix that you are supposed to use on it's own, the second is an additive you add to water - the clue will be that the corrosion blocker comes in a 50ml bottle, but the premix comes in a 1L bottle

both contain ethylene glycol so you probably won't be needing a biocide anyway

copper sulphate is the same stuff you might have used to grow blue crystals as a childs science experiment, not something I would prefer to use in a watercooling system anyway personally

feser base corrosion blocker(yeah 50ml bottle) im sometimes a bit over protective and wanted to safe guard against everything so just jumped in and bought the lot. having zero chemistry knowledge wasnt aware you cant mix things like this and there certainly wasnt anything to tell me otherwise except these forums
