I'm pretty new to the business of maintaining pools, having started in june. I have picked it up very quickly and can run the place smoothly except for when it comes to the becs system on my small pool.
I can't seem to figure out how to get the system to maintain a constant ORP without is spiking.
After many trials and tribulations I have come to two conclusions. Either the rotachem machine that feeds the chlorine has too high a volume output (as it is the same volume as my large pool) or that the becs may be broken.
I have come to these conclusions as My pool company have supposedly changed the sensors, I've pinched the line that feeds chlorine to restrict the volume output and I've tried controlling the chlorine manually myself, timing the feed.
The pool is a 15,000 gallon outdoor pool that has a constant good level of all other chemicals.
