Anyone like to comment, his idea seem reasonable for those of us with ORP controllers and acid feeders in a both a non salt water system and a salt water system, particuarly for older pools.
I know it deviates from the standard CYA method but is it worth considering?
He feels that this is suitable for residential pools with a moderate load (not commercial where one would have to feed the pool all day), targeting an ORP of 650 by raising the ORP at night presumably to above 650, my guess is 700+, by running the pump only when it is dark or starting in the late afternoon. Trial and error as regards to feed %, power, and pump running time until one acheives the desired effect depending on pool size of a minimum CYA of 650 before the pump starts up. He runs his 26,000 gal pool from 4pm to midnight.
If one had a pool party one could always switch it on prior, during, and after to neutralize the load, or add liquid chlorine.
The only down side I can see if that if your cell failed you would get an algae bloom but that would happen with a CYA pool as well. So one still needs to make sure ones unit is working daily. But are there any other side effects I am not aware off?
