My test #'s are as follows:

FC-3.0
TC-3.0
PH-7.2
TA-50
CA-350
CYA-25

My TA is low so I added 2 Lbs. of Baking soda and will re test tommorow. I am looking to get this in the 80 - 120 range.

That is the only adjustment I have made since this testing.
It's a good one. I prefer 100-125--but no higher with your pool.

I feel the CYA is slightly low, Is it and What is the best way to increase this? Triclor tablets?
It is low. I like to see 30-50--I normally prefer 30, but sometimes 40 or 50 is better. Especially if you have LOTS of direct sun. With your low pH do NOT, NOT, NOT use Tri-chlor tabs--they will lower it still further. You can get pure CYA. Add no more than 1/4 of what they recommend--It's easy to add more but difficult to get it out.


I feel the CA level are too high, I would like to see these numbers in the 180 - 220 range.
350 is still well within recommended range for your pool. 400 is the highest you should go before dilutiing it down. I wouldn't mess with it. Suggested range is 200-400 for your pool.

I have lowered the PH and started heavy areration with our waterfalls and spa jets.
WHY, pray tell! Your T/A was too low you had to add to it. Why lower it more?? You are doing absolutely the wrong thing here.

Do I want to add Leslie's stain and scale enhancer? We did get some scaling on our cement rock sides, our pool as no tiles.

Any and all comments are appreciated.
