does the aqualogic generate while the 2 speed pump is on low?
This year i have been running the pump on low 20 hrs. On high 4 hrs while the polaris is running. trying to save a little$$$
i have a northstar 2sp pump (1.5hp) and 2" piping. this baby will move some H20. 22k pool. the pool has 6 returns, 2 skimmers and main drain. all are fine. Pool looks great! water is clear.
#'s are great. I've been using ben's/TFP test kits for years.
except my 2.5 yo SWG has stopped reading salt levels correctly and chlorine production is down. taylor kit reads salt @ 4000. The aqualogic reads 2300 and asking for salt. I've cleaned the cell twice this year and it has always looked fine. up to 65% output to get 2-3ppm. last couple of years only took 25%. No blooms, low bather load, regular water care, BBB etc.
the only change is the pump speed. on low it is only .25 hp. diag menu looks fine. flow switch fine.
I think the cell is going. i turn the pump on high for a few days and no change in chlorine #'s or SWG salt reading.
CYA 100 and shocking pool does not change anything SWG-wise.
you think it is a flow problem? too low for SWG to work correctly?
