I am responsible for daily operations for several semi-private pools and spas. By semi-private I mean they are not public; they are located in retirement villas, condominium complexes, apartment blocks, etc. I took over this position only 3-4 months ago so I have been maintaining the regimen that previous operators had developed. I've been slowly making changes as I become more educated as to each pool/spas usage and quirks and the products being used, but now I have a question that nobody seems to be able to answer.
Of the six spas, there is one 10,000L, one 1,800L, and four 5,000L. All are maintained using BioGuard products, all are using Trichlor pucks. Every spa is maintained at 102-104 F. All are concrete and tile except the tiny one. There has been a daily regimen in place of "a squirt of Anti-Foam" (just enough to dissipate any foaming when the jets are on) and "a shot of Polysheen Blue" (average seemed to be about 15mL, more if water was not clear). For those familiar with the product, you will know that the directions for Polysheen Blue say 15mL per 10,000 L *per week* (it is intended for pools).
I have had one person tell me that Polysheen Blue is not suitable for use in high temperature waters such as a spa; however I can find only one retailer's web site which says the same thing. The manufacturer says nothing about it.
Can anyone give me some more information on this? I can say that it *seems* to be working, however I am concerned about using large amounts of a potentially unsuitable product, possibly building up contaminants and TDS faster, and wasting quite a bit of (other people's) money in the long run.
As a side note, these pools have been shocked every Monday using 1/2 bag of BioGuard Smart Shock (1 bag is meant for a 40,000L pool), however as stocks run out I am starting to switch to Oxysheen (potassium monopersulfate). They are also drained every 4-8 weeks depending on TDS buildup.
