Hayward S244T sand filter GPM/FT 20
3/4 hp PAC FAB Challenger pump
Pool Pilot ST 220 SWG
FC 8 high due to fighting black algae
CYA >100 trying to reduce over time (black algae came 1st)
I have several questions but will start with SWG (PoolPilot bought Sep 2004). We were getting check cell light with low volt and low amps (ex. 12 : 3.3) on cell power 2. Not helped by cleaning cell. Bought generic Compupool cell but still getting same results. Not sure if cell is defective but hate to buy a new non-generic cell and still have the same problem. In the booklet it says volts go up when cell fails which is not the case although the amps are certainly down. In the past the cell did scale up but now hope to avoid that with better management.
We have a lot of pitting in the plaster surfaces of our pool (also due to poor management). We can live with the way it looks but I am wondering if it could cause other problems.
We have killed off black algae (was all over the pool) thanks to following your advice. There are still some faint shadows and I wonder how long I should keep the FC high.
I appreciate any info or advice you can share
