Do I need DE?

Hi, Brad,

Given your indistinct method of measuring Cl and your CYA of 90 (maybe), I submit that the filter is not your issue.

To get that pool to breakpoint chlorination and clear it up, you should be running your Cl up to around 20-22ppm and KEEPING IT THERE until your water clears.

Run your pump 24/7 'til the water clears as well.

Can't answer about the SWG but I'd turn it off....why produce Cl when you've already got it in there?

You simply have not kept your Cl high enough...long enough.

Additionally, it the cheapest, simplest thing to try. We all need to remember what our Dads taught us..........check the easiest things first.

I measured the CL with a "drop based" test from WalMart. It's the one where it turns yellow. It only measures to 5ppm so I diluted with three parts water and still got 5 which told me it's at least 20ppm. According to the "black dot" test for cya - it should be around 90, but the pool store told me last week that it was 42 and I've only added 3lbs since. So I am really chasing my tail here. I will keep the CL up, but it only checks for TC. Does anyone know if there is still a pretty good waiting list on Ben's kits? Thanks for the replies and please keep em coming. It's very encouraging (right now I need that).

Thanks again,
Brad

Hi, Brad,

I'll repeat three words in my post...."KEEP IT THERE". If your Cl was 20 last night, it won't be this morning.

I think you're on the right track but it is imperative you keep bringing your Cl back up to 20 or so every chance you can.....three times each day is not too much.

Your water will sparkle shortly.
