New Pool; New Kit; New Numbers

This my first pool and like so many others I have already learned so much from this site. I can't thank you enough.

In fact, I've learned enough to know to question the pool store clerk when he began telling me "I need 10 pounds of this, 54 pounds of this, etc." :confused:

When I asked him to see the results of the tests he told me the computer takes the numbers and recommends the necessary chemicals. I decided to pass on the computer's recommendations for now, pull out my PS234S kit, post my numbers, and get a second opinion.

My pool is 35,000 gal vinyl, Pool Pilot SWG, DE Filter, Heat Pump. Water is crystal clear, 82 degrees.

FC = 0.5
CC = 0
TC = 0.5
ph = 7.0 - 7.2 (I think this is a little low)
Alk = 40
Cal = 50
CYA = 0
Salt = 3600-3800 ppm (Pool Pilot says 3700 ppm)*

* My salt was 4400 ppm, which I thought was a little high, so I drained out some water and brought it down. I'm going to repeat this process and try and get it down to 3000-3200 ppm.

I've been testing everyday for the past week (just trying to stay on top of this until I get the hang of it) and the numbers have been pretty constant.

Thank you again for all the great info.

Well, you didn't ask for comments but that never stops the determined!!

You need to get CYA in your pool. Without it you will not be able to hold a Cl residual during the day to sanitize your pool.

Thanks Dave. (Of course I want comments! :) ). As far as CYA goes, what should I raise it up to?

Note: I forgot to mention that I run the pump for 10 hours during the day (6am-4pm) and the Pool Pilot is set to 55% (Dig 220 Sc-48 cell).

Follow the SWG's recommendations. I think most of them suggest 60-80ppm altho others on this forum have decided to use less....around 40-50ppm.

Dosage will be on the CYA container.

That should allow you to run Cl a little higher........Maybe 2-4ppm.

I'd leave pH and Alk (which is also low) alone for a little while. The SWG should naturally bring your pH up and Alk will follow (altho you still may need to increase your Alk a little up to around 100....test again when your pH gets up to about 7.4)

You might bring your Calcium up to 150. Normally irrelevant for vinyl pools, there has been some discussion on the forum for pools with heaters. I don't have enough knowledge to comment on the merits but 150ppm Calcium certainly wont do any harm and may help your heat pump.

Happy Swimming
