Testing ph in new loop

[Saul_]

I'm using Mayhems Ultra Pure H20 in my new system after testing the ph after a week it was neutral. I will test again and if it's the same (neutral & 2 months old) ) I assume I don't need to add the mayhems biocide I purchased ??

I didn't think biocide was anything to do with pH... I wouldn't want to run without either biocide or a kill coil

Biocide has nothing (or little) to do with pH, biocide is used to kill off bugs in the water. Bad pH is more indication of corrosion risk.
