Hi all have been lurking for a few months and need some advice please
I am in Australia and had a new fibreglass pool installed in March. It has a AstralPool EQ25 control system (http://www.astralpool.com.au/sites/d...HLORINATOR.pdf) which controls PH and ORP with a SWG and automatic acid feed.
I've invested in a Taylor K-2006C test kit which is excellent and have spent the last month or so getting all my levels balanced in accordance with the TFC guidelines, so far so good! Going off the suggestions for SWG pools I got the CYA levels up to 80 and FC using the test kit to get to around 6 to compensate.
Now my main issue to that the control system is going haywire with ORP fluctuating wildly (700+ readings in the mornings and 580 ish at around 5pm) and the SWG is pumping out loads of chlorine when I don't think its actually needed and its eating through acid at a crazy rate all of a sudden. After re-reading the manual (I know, I know..) it appears that a CYA level of 80 is way too high to be using with this type of system and they recommend not using it at all or at most having a range of 10-20ppm.
What options do I have now to sort things out? Am I looking at a pretty much total drain and refill of the pool (water is expensive here) to use this system or am I best to switch the system off and manually balance the pool for the summer season (its the middle of winter here now) then see how it looks at the end of summer?
I paid a lot of money for the system with the pool so not using it isn't ideal but I think I'm right in saying that there is no easy way to bring the CYA level down so the system works correctly?
