Did a new pool build last year, had it open for September and October before closing.
Opening now. Water looks great but working to lower TA from over 200.
A couple random thoughts.
I have a variable speed pump.
I set it to run at a 2100 RPM or so for 22 hours per day to keep the SWG flow high enough. SWG I have set for 40% production.
Then for two hours a night I have it run at 3400 RPM for clean cycle.
I'm still guessing on my GPM flow. I have 1.5" piping all around including at a bottle neck right before the pump.
The other night I came back late from a travel trip and heard the pump screaming at the high speed.
Here are my random thoughts.
1. At 3450 RPM, my "guess" is that I'm at 75 GPM. But I'm suspecting I might be trying to push more water through than is really feasible and I'm just stressing the pump. Maybe I have a true limit on what's productive on the high end.
2. SWG - I'm thinking of running my pool at a lower speed that what the SWG will generate at. Then run it at a middle speed for the SWG to work. So instead of running 40% for 16 hours, run 100% for 5-6 hours (or whatever it ends up needing). I'll tailor in the correct SWG production percentage to match once I have everything stablized.
3. Skimmers. How do I know if they are actually doing anything? I have two skimmers and dual drain in the deep end (which goes to one 1.5" pipe for the drain. Each skimmer with dedicated lines. I know water flows through them, but with an auto-cover, is there main purpose to collect the leaves? Sometimes I just see a leaf or two in there while i also have a leaf or two in the corner of my pool that never wants to actually flow into the skimmer.
4. If chemistry is good and I stay on top of things, what's the reason for "turning over the pool". Some say once per day, some say twice. Is the main reason to just keep water moving to prevent algae on walls, or should it not matter as much if levels are correct and the pool is closed often?
I know, a lot of variables. I'm thinking of doing some experiments today by making my own PVC returns for doing a "true test" of GPM at the various pump speeds to get a better handle on my real flow rates.
I believe the best guess I have gotten so far is from noting the RPM to trigger the minimum flow rates on the heater and the SWG. Seems like 2000-2100 RPM = about 40 GPM for me.
Appreciate any comments.
