I have a 25,000 gal saltwater pool that we are having issues with. It was chlorine when previous owners had it, but we had it converted to salt in April. The wrong size cell was installed for the hayward aquarite (the size for pools up to 15000 gal was installed). Our pool turned green and I had the water tested and someone come look at it, which is when we discovered the cell error. We will buy and have the right one installed, but even though the pool guy and I added a bunch of stuff to straighten out the pool, I'm not sure what else needs to be done. The water is looking better, but here are my stats (also my 1st time using the TF-100 test kit.
CL 5 (I have a really hard time telling between the shades of yellow)
Free Chlorine 20 (even after 40 drops, still slightly pink tint)
combined Ch 7
Total Alkalinity 150
CYA test 40 ppm
Friday was when the pool guy, and I added a bunch of stuff to help balance it: 32 lbs sodium bicarbonate, 5 lb stabilizer (and a second 5lb bag added the next day), 1/2 bag of aqua salt, shock, 1.5 lbs soda ash. He also cranked up my chlorine on the Aquarite to 80% - we have issues since the cell size is wrong, but should I turn this back down now?
Any recommendations on further balancing out the pool would be wonderful!
