30,000 gallon, in ground, vinyl liner, chlorine, de filter using fiber clear: Help! I opened the pool with no problem and the water looked great after a little cleanup. We even warmed it up and went swimming. Tests all looked good except the chlorine got low around 5/21 and I was not able to keep the cl level high enough since. Also, cya has gone from 81 to 8 over the last 2 weeks with no significant water removal.

I have shocked it 2 days in a row and I still have no chlorine, but TC is 5.6

In the past, it was always a struggle to keep the cya down as the chlorine tabs have it in them. Does anyone have a clue?

Thanks,

Todd

Welcome to the forum!
How are you testing your pool water chemistry? Please post a complete set of test results from your own kit.
I suggest you read ABC's of Pool Water Chemistry.

Marty,
First, thanks for the reply. Here are 4 tests I had on 5/8, 5/21 , yesterday and today. Yesterday and the day before, I shocked the pool with 4 pounds of calcium hypochlorite. For some reason the cya disappeared and I can't keep the chlorine up although the TC is now way up. The pool is cloudy white. I run a large Hayward DE filter with Fiber Clear instead of DE. I does not take long for the pressure to build up.

Yes, I have read the chemistry book.

Thanks,

Todd Kroehle

You need a proper test kit. See Test Kits Compared. I suggest the TF100 or the Taylor K2006C
While waiting on your kit, add 5 ppm FC worth of liquid chlorine each evening with the pump running.
When you get your kit, run a full set of test results and post them here.
 
Hey Todd and Welocme !!! So here’s the deal. Leslies is a corporation. To a corporation you are nothing but a metric. They have a spreadsheet in the back listing many metrics. Like that each customer nets an average of $127 for the store. And they spend millions upon millions of dollars trying to squeeze more from the customer. If they get $145 per customer, they need $153 next month. Wall Street is never just happy. If this store gets its $153, but the other store gets $155, then they get corporate pressure to either follow suit or find new employment.

Oh yeah, you and your pool. Almost forgot. They don’t care in the least. The more they mess it up, the better it looks on a spreadsheet to a district manager. There is nothing free about a free water test.

Anywho you found us. We’ll help you on the cheap for nothing in return but good feels from helping a fellow pool enthusiast. Get a reliable test kit and it will be smooth sailing thereafter. :)
