initial test results

[p.p.h.]

Just started up my new 10000 gal Pebbletec pool 2 weeks ago. The pool company came by within those 2 weeks a few times and took care of the water for me so I never tested it until now. Heres my results thus far.
CH=275 CYA=80-90 FC=4.0 CC=0 PH= 7.4-7.5 ALK=140-150
Water is 70 degrees

Any thoughts on what I need to do or does something need adjusting?
The SWG is coming within the next few weeks, where should I get my levels at before they install it? Any special preparations need to be made?

Well, p.p.h., you may have to change your username to Ph.d. (of pools, of course).

Looks like you've got everything under control. Your CYA is probably exactly what the manufacturer recommends. If you made me complain about something, you might keep an eye on Alk. I wouldn't let it drift much higher but I don't think I'd undertake any active measures to lower it, either. Looks like your all set for Summer.

P.P.H.

VERY good start-up numbers!

Your T/A is too high for a pebble-tec pool, but not by much. I agree with Duraleigh that you are best off leaving it alone. If your water gets cloudy, then you should lower it.

Try to keep your FC over 5--your CYA is 80-90--higher than I like but not a problem if you follow Ben's "Best Guess" table for the chlorine. I believe 5-8ppm is the range you should hit--but go by the table.

At that time, follow the plan laid out in the Alkalinity section--lower pH to 7.0-7.2 and aerate your water until pH rises over 7.3. Check T/A. If it's STILL too high, lower pH again to 7.0-7.2 and aerate until pH is over 7.3. Keep doing this until T/A is in the target range.

But those are fine start-up numbers!

Thanks for the help. I'll keep tabs on the alk. This forum is a great resource.
