Our pool is being built and is almost ready. We have opted for a Delta UV system (ES-10) and I have a couple of questions about the level of CYA and chlorine. Do you still run the recommended CYA levels of 30-50 (I will be using the BBB method for maintenance), or do you run it higher as if you had a SWG, around 70-80?
I understand with a SWG you can run the FC at 4.5% of the CYA levels (as apposed to the non SWG pools where its more like 7.5%) because in the SWG itself there is a high concentration of chlorine before it enters the pool which kills a lot of the bacteria, germs, viruses, algae, etc., which is exactly what happens in the UV unit. So this is why I'm questioning the right levels of CYA (I assume the chlorine still needs to be about 3-5).
Cheers...
