Hey guys I am new to the forum but I have seen the topic on pools with organic stains. Often times they stayed to use liquid chlorine and this will clear up the problem. It's approximately 18,000 gallons. The stains look to come from the tree above which I have attached a picture as well. Upon trying to get this to clear up I also see that the bottom of the pool is becoming either dirtier or developing Algae. I found the board because there were other similar threats that also talked about this topic. Could you please give me a play-by-play on what to do, how long to expect and how much adjustments I should make to get the appropriate cleaning going, including any scrubbing with brushes.
This is my first year with an old gunite pool and I'm getting frustrated...thank you so much for your help
