Hello Everyone (& hopefully Chem Geek),
I'm getting ready to replace the 20 year old pool heater and filter along with a 5 year old grinding pump. The pool has blue stains and scale on it from the old heater. Also when I pulled one of the spa jets I found it had a brown scale on it.
Before I put in the new equipment and get it re-plastered, I'm wondering if I should lower the PH to 5, 5.5, 6 or something to try and "etch" out the old scale and loosen / remove any embedded copper in the plumbing that may come out later and stain the new plaster? If necessary I could bypass the heater while doing this to avoid any more copper getting into the pool?
To avoid future blue staining on the new plaster, from the existing situation, should I use "CuLator Metal Remover now (I saw Chem Geek had a thread on this) as part of my plumbing etch process, or since the water will be pumped out for the new plaster whatever copper residue will be pumped out so I don't need to worry about it?
Does anyone think this would work or just chance damaging the 20 year old PVC plumbing?
Thanks for your help and insight, Tom
