We bought a house last fall which has an in-ground pool/spa (3000 gallons) and have been going through the pains of learning about pool chemistry. Over the last week or so, following the recommendations on this forum, I added borax and muriatic acid and the pool pH has stabilized and chlorine levels have settled down. I would like to add an SWG such as a CompuPool CPSC16. My local supplier of pool supplies said my pool/spa (8'x16') was too small for an SWG, basically because the SWG running for a smaller pool would make it difficult to maintain the appropriate levels of free chlorine. In other words the SWG would be "overpowered" for the size of the pool.
During the summer months we'll be keeping the pool at swimming pool temperatures and on infrequent occasions during the rest of the year raise it to Spa temperatures, otherwise letting it follow ambient/ground temp fluctuations (50 to 65 degrees).
I really would like feedback from the forum as to the feasibility of using an SWG for this pool. Does my local dealer just want to keep selling me chemicals or does his argument have validity?
