I had work on my pool a few months back and haven't had a chance to leave feedback until now. I fought with Black Algae for over 6 months and tried most everything. I finally called August at Del Sol and found him extremely knowledgeable and he got rid of the problem. His pricing was very fair and I would use anytime I need help with my pool. So far the best pool company I have used in 15 years and I highly recommend them. I just recommended him to a neighbor and they are calling him tomorrow. Honesty,integrity and fair. Doesn't get better than that.....
