Pool Stains and algae buildup often happen. This is best treated with an acid wash. This is a process that can be very dangerous if not done professionally. We are also acid wash specialists. You could try this process yourself but it’s best to leave it to a professional to avoid damaging your pool or health. While acid washing is something that usually only needs done every 5 years or so with a proper maintained pool, please call us if your considering having it done. Serious skin burns and other health conditions can happen if these chemicals are not handled properly and professionally.
