Hi I'm new to the forum and pool ownership so please bare with me as I have so many questions and not sure how to post them. But here goes.
First- is what should be the correct level of CYA for my SWG pool. My Hayward T-3 manual says 30-50ppm, online web references anything higher that 50 is a waste of money as CYA as its has beminishing returns above 50. My local PAP store says no less than 90 and here on this site, I'm reading 70 to 80ppm. So using my Taylor K-2006 gives me a 70ppm reading, but what number should I be shooting for.
Second- I've noticed a brown staining on plastic drain covers and jets as well as a blotchy spots in the shallow end of pool and steps. so I applied Vit C in sock on them and stains immediately disappeared, leading me to believe I had iron staining. (water analysis showed 0ppm Iron). I purchased and followed a CU-later program using both absorbic and citrus acid, a sequestering agent and their proprietary polymer to collect the sequestered metals in a sack placed in the pump strainer basket. The Culator Kit was good for 20k gal pool so I used half in first application and so results. The Mfg. wants you to maintain chlorine at <1ppm for three weeks after treatment which was impossible in my 5K gal pool so it ended up plating back out to pool surfaces after a month or so. My second attempt may be successful as I maintained <1ppm for three weeks and then remove the polymer sacks and hopefully the iron with it. But now I have the early signs of green algae growth in corners and slow moving water areas due to the low chlorine levels during CuLator treatment even though I was using a linear a polyquat algeacide and Chl use is in high demand from my SWG, which can't keep up with demand. The water after extreme brushing and vacuuming is hazy, but not green.
So today per this site's recommendations I'm on day one of a slam using 1lb of Cal-Hypo and looking for any recommendation going forward.
I know now this is a book info requests, but wasn't sure so I spilled my guts......help me out please.
