I SLAMed my pool in mid April after re-balancing pool chemistry after winter rains. Turned salt generator off, OCLT quickly stabilized, I let CL drift back to normal, and thought I was good. It's now mid-June and algae is back. Why is that? Not bad, but I see algae when I sweep the walls and...

Getting my pool ready for summer after 40 inches of winter rain. TA, pH, and CH dialed back in very quickly using PoolMath. I took the CYA to around 60 before re-reading in the SLAM instructions to keep it low. I will raise it a bit more when done with SLAM. How long should I expect to...

Re-balancing after winter rains (N Cal). I have a little algae on my vacuum, but pool walls look good and water is clear. My latest test results... - pH 7.5 - FC 5.5 - CC 0 - CYA 60 - TA 50 - Calcium 300 Salt pool I was expecting to SLAM it to get a good baseline, but given the readings I...

SLAM'd my pool in late May because of some algae; took FC up to recommended 24, stable overnight, then let it drift back down. Pool looks great. Pool still looks clear. Kids are gone so not much use this summer. My wife brushed pool today after about three weeks. She said there was a...

Getting my pool in shape for summer, the pool chemistry looks good but I get algae dusting the side and on my vacuum 27k gal salt pool FC=3.5 CC=trace (barely pink) TC=4 pH=7.5 CH=276 (low end of normal) TA=70 CA=40 I recently serviced the DE filter. The salt generator (CircuPool RJ+60)...

I just received my TFTest 100 kit to replace an older Taylor K2006 because I want fresh reagents. When using the R9 dropper the drops came out faster than the other reagents or my Taylor kit R9 reagent and the drops were smaller than the other reagents or the Taylor kit R9 drops, maybe half the...

I can't get rid of algae on the walls and bottom of my pool. Water is clear...until i sweep down the sides. FC is off the charts high. More yellow than the highest color PH is 7.6-7.8 TA is 90 CH is 270 CY was tested at pool store at 100. I haven't been able to check with my kit but with the...

What is recommended to raise CH in a SWG pool (pebble-tec/plaster)? I used CaCl flakes in the past but recently saw a YouTube video claiming that is not good for SWG because it plates calcium off on the generator. https://www.youtube.com/watch?v=gevc2VoJc0k I have been fighting build-up on my...

I have a Hayward swimpure that is probably 4-5 years old. The past couple weeks the salt indicator has been falling, which made no sense so I had it tested and it is 3100 ppm. Display says 2100 ppm. Low salt and check cell lights are lit, and generating light is dark. Pool chlorine level...

Time to replace the pump on my pool; the old one is screeching at me. I have a 28k gal pool with solar heater (panels are on a shed, 5-8 ft above water level) and suction side vacuum (Hayward pool vac ultra). Filter is Hayward DE 60ft2 and I have a salt water chlorine generator. 2" plumbing...
