After buying a hot tub plus pool equipment, and spending what a new car would cost, the expectation (and promises) were of high quality of service. Sadly not the case: would you wait a week to have a nearly new car serviced so you can drive it again? Suddenly they only come out where I live "once a week". So, what they sell is good quality; the quality of their service is severely lacking! Had to get someone else to service, voids warranty, etc., etc. NOT RECOMMENDED!
Happen to stumble on this, and have been using Biogurd chems for 12 years and find them to be superior. Called the factory a few times for tech info…
We recently bought a fixer upper and contracted him to resurface our pool. He told us on Monday that it would be ready on Friday .. three weeks later after a lot of hassle the pool was completed or so we thought... now there is a leak and he wont return calls or texts... use with caution!
