Our pool is several years old, and we have never fought algae like we are this year. We even opened the pool a month earlier than normal. Pool pump has been running for a month now 24/7. Pool was green upon opening. Have a Pentair Cartridge Filter and SWG. Went to local pool store and was sold $150 in chemicals; case of shock, stablizier, algecide, etc. That turned the pool from green to blue cloudy. Swept the pool floor with the Dolphin M4 Supreme several times and cleaned the filters every time.
After two weeks of this, we went to the local Leslie's store to have the water tested. Manager told me there must be something wrong with the SWG because chlorine is registering 0. Called the company that sold and installed the SWG two years ago, and opened the pool. They said nothing was wrong with the SWG other than the weather was too cold to be generating chlorine. They said dump another case of shock in the pool, and no need to buy anything else.
Algae on the bottom of the pool is lessening, but still there, and more forms everyday after cleaning the bottom. This weekend, I decided I would once and for all get this pool in shape. I bought two more cases of shock, a vacuum and hose. I first vacuummed the bottom of the pool, then I took apart the filter and cleaned the cartridges real good. Put them back in and fired up the filter again. Added a case of shock in the evening.
The following morning, pool was still clear, but there was newly formed algae (brown/grey looking) on the bottom of the pool floor. Chlorine up to 4.2, Ph 7.4, TA 120, CYA at 40. I got in the pool and felt the walls, they felt like sand. I brushed the walls three times until the walls were smooth. Added another case of shock.
I was sure I finally killed it all. So when I went down to the pool this morning I was so disappointed to see that brown/grey algae on the floor, and more than the day earlier. I took readings, now Chlorine is up to 10.4, Ph up to 8.0, TA 110. That's all i had time to measure.
What the heck do I do now?
Thanks!
