pH level in the loop

Hey guys, when I set up my loop with DI water and biocide the pH level of the water was showing at around 6 - 7, but since then I've added a corrosion inhibitor as well. Anyways, I checked the pH level again yesterday (dying the water red, so wanted to check before the dye skewed results) and its gone to around pH 10 - 11 since adding the corrosion inhibitor... Is this far too alkaline and likely to damage anything, or is it safer to be on that side of the scale rather than be too acidic?

Cheers in advance for any advice :D
 
Made an error in the original post, I'm actually using your ultra pure H2O not DI water... Forgot I'd bought that! Anyways, to the answers! I'm currently using Mayhems Extreme Biocide and the corrosion inhibitor shown in the pic, both used at their recommended ratios.

Is it likely to damage anything in the system if it's left at those levels (only currently been like it for a couple of weeks) or should I just leave it until the next time I need to drain the loop? Cheers Mayhems :)

Oh dear, guess I should probably drain the loop AGAIN then and chuck the stuff out :D

I'll get this right eventually if it kills me lol any particular brand / product you'd recommend, or should I just go with pre mixed so I can't balls it up again?! :D
 
Or, rather than go through the ball ache of draining the loop and bleeding it all again, do you think it would be OK to just massively dilute it by repeatedly emptying the reservoir (I have a tap on the pump), refilling with more H20, running for 10 seconds and repeating half dozen or so times to get most of the corrosion inhibitor out? Would save a lot of hassle so might try this first unless you REALLY don't recommend my random German chemicals :D
 
That's some more positive news, can I ask how much of it you put in? Hoping I haven't completely balls'd up and misunderstood the German label :P
 
Ah that's good news, I put about ¼ of it into a loop that holds 1l, so shouldn't be too far out then! Tempted to maybe just dilute it down a bit now, recheck the pH and see how it goes...
 
So in theory, the worst it should do is stop the biocide from working properly, but it shouldn't do any long term damage to components? Need a degree in chemistry to understand this watercooling malarkey :D
 
That would be awesome cheers, but you're right, should probably drain it and refill but it's just finding the time to do it atm, and bleeding the loop again gives me nightmares lol

I actually went a bit overkill and added a silver bullet as well. I know you don't NEED both but me being me... Why not?! :D
 
Damn, so the mixture ratio it gave on the website is a mile out! Cheers Mayhems, I'll gradually flush the loop out with some fresh Pure H20 until it's at a more sensible level :)

Now that you know what's in it, would you recommend using it in a standard loop? Using Pure H20, Mayhems biocide and red dye apart from the inhibitor. And don't worry, if I run into any issues caused by my own stupidity I won't blame it all on your water lol
 
That's OK but thanks for the offer Mick, I'm sure you're busy enough without idiots like me taking up your time! I'll drain the loop (or massively dilute it) over the weekend if I get time, hopefully bring it back down to nearer pH7. On the plus side at least my constant balls-ups are keeping your Pure H20 flying off the OcUK shelves lol :)
 
Ah, makes sense. How would you recommend disposing of it? I've got an oil container in the garage for used car oil, safe to chuck it in there and dispose of at the local garage?
 
Awesome, cheers Mick, that's my Friday afternoon (hopefully) sorted then!

You might be onto something there NoName, but I've just checked and still got almost a litre of Pure H20 left in the cupboard so I'll be diluting it with the posh stuff again this time ;)
 
Right, I've run some new water through to dilute it (and managed to let some bloody air in :mad:) and it's now around pH 8 - 8.5, so I think I'll leave it at that for now. Cheers for all the help and advice guys :)
