Sam's Clear Pool Service is the best, Sam takes very good care of my pool. Anything that needs to be taken care of he is there to fix it.
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…
I had a leak in my pool they did a great job repairing it and then I had them resurface it. It looks great!
