All ... brand spanking new to this forum and receiving bids from pool builders right now. This post (and others) have proven invaluable in understanding the truth in claims re. pool sanitation.
We've currently received bids from 4 pool builders who each recommend the following sanitation options: 1st) SWG and 2) Ozone/Chlorine hybrid system. Re. SWG - One of the builders specifically stated that they've seen rock/decking corrosion and damage traced back to the salt used in the SWG setup. They have begun requiring a liability waiver for SWG for this reason. In fact, there have been news stories in Dallas re. the same phenomenon. Curious if anyone can add veracity to this claim on SWGs?
Also, on another front, I am attempting to assess a possible alternative to reduce chlorine requirements but have had a hard time finding "real" information. I am curious if anyone has used / considered a hybrid UV (Spectraclear, UV254, UV Clear, BioLab UV) + chlorine system? It is easy to find many comments (here and elsewhere) that UV Systems can't work on their own - as they have no residual sanitation method. The UV companies also verify this and recommend chlorine be used in conjunction with their solution(s).
However, they also claim to be able to reduce the chlorine requirements by anywhere from 60-80%. I am wondering if pursuing a UV setup + some form of chlorination would work [while achieving a % reduction in chlorine requirements]? None of our pool builders are familiar with UV systems, so am attempting to verify this approach on my own.
