Is the pool company BS'ing about their chemicals?
We just finished a pool with Anthony & Sylvan. They use Jayson Pools to service the equipment and do the start-up. Jayson tried to hard sell me on paying $750 to buy 3 months-worth of chemicals. When I said I would consider it but wanted to check pricing against competitors they claimed that I am only supposed to use Anthony & Sylvan branded chemicals and that if I don't it could void my warranty. I challenged this and asked them if their chlorine, etc., is really different than others. They dodged a direct answer but again said I would be "risking" my warranty if I used other chemicals.
This sounds like BS too me but I am curious if anyone has experience with this.
