I recently bought a house with a pool and it started getting algae as soon as i moved in. Recommendation was to SLAM, bought a TF-100 test kit, got my PH to 7.2 then started the SLAM process. I started the SLAM process about three weeks ago but when I started the pool was only filtering through the vacuum, a backwash had not been performed under my supervision and I was testing the FC once every other day.
In the last week I have figured out how to have it filter through the main, started backwashing 3-4 times per day, testing the chlorine twice per day (best i can do with work) and keeping it around 10. I have noticed that it is difficult to keep it right at 10 because of the funky measurements it as for and my inability to get it exact, so sometimes when i measure it again, FC will be closer to 12.
Overall, the look of the water has not improved at all. When i run a backwash in the morning it dumps out a couple of minutes of very greenish water, the rest of the backwashes, 1pm, 5-6pm, and midnight all run very clear from the get go.
The filter has been running consistently for a few weeks.
I would think by now there should be improvements in the water color. Should i restart the SLAM process by getting my PH right by letting it sit for a certain amount of time then testing it again?
From my measurments the pool should have 14,000 gallons, CYE came in at 20, no chlorine in the pool when i started this and the PH was at 8.4. Hayward sand filter. If I'm missing anything please let me know and thank you for any help or insight you can offer!
