Please can anyone give me advice- I am completely lost!
We have a saltwater pool. Since 6 weeks we all of a sudden have no FC reading.. I thought it may be the cell which needed replacing (was installed 6 yrs ago...). Bought a new one (Zodiac clearwater LT-15). Installed it. Nothing! Water passing through the cell is plain clear .. should it not be cloudy, or have bubbles to show it's producing chlorine? Is it broken?
Could it be that CYI is too low?
I don't know what to do... any advice highly appreciated!!!
