I’m finding it a bit tricky to set up our new RJ-45+, which I installed in June, six weeks after it was re-plastered. Since startup, I’ve been running the VSP for 20 hours a day at 1,350 rpm, which provides 23 gpm of flow and turns over our pool’s water 1.9 times a day. Running the VSP at this low speed our water is crystal clear and the CC readings have been at or nearly 0.
Our pool only receives 6 hours of direct sunlight a day and it takes time to build up the temperature in the spring as I do not have a heater. I use a solar cover anytime we’re not in the pool to conserve that heat and we don’t get into the pool every day.
After reading threads on this site, I’ve learned that newly plastered pools can take some time to obtain a stabilized pH and TA. I have been chasing a rising pH all summer and while it’s slowing down, I’ve still adding up to 20 oz. every other day to keep the pH around 7.6.
The RJ45+ is doing its job but I’m finding my FC levels are higher than TFP’s ideal levels even though the unit is turned down to 15%. Measurements taken this morning:
FC – 5
CC - < 0.5
pH – 8.2 (added acid to reduce to 7.6)
TA – 80
CH – 375
CYA – 70
Salt - 3200
Temp – 82
Normally the FC is tested at 3:30pm in the afternoon (when the pool is shaded) but I checked it this morning as I won’t be able to this afternoon. FC test in the afternoon runs around 7.0, +/- 0.5 ppm. A month ago, I turned CL production down to 10% for awhile but it dropped off to around 4 ppm so raised it back to 15%.
So my questions are, is what I’m experiencing with my FC level seem to be normal? Any issue with the FC in the 7.0 range? When can I expect the pH rise to slow down even more?
TIA,
Gary
