Trying to balance water

[DirtYCreeKMemaw]

Good evening all, I've been reading and testing water and I finally give up and decided to post for help!
I have a 20' x 4' round AGP (Pro Series metal frame) and have a Hayward 14" Sand filter w/40gpm pump and an SWG.

Here are my test results as of this eve...(via Taylor 2006)

Salt 3000ppm
FC 1.0
CC .5
pH 7.6
TA 70
CH 80
CYN zero (best I can tell after 3 test!) I added 1 lbs over week ago.

So I need to raise the TA and the CH and CYN...I just don't know in which order to raise what 1st!

My SWG manual recommends these "Ideal" levels

FC .5- 3.0
CC 0
pH 7.4-7.6
TA 100-140
CH 200-400
CYN 20-40

So...any input would be greatly appreciated!

ps...the hayward pump is new this season.

First, forget about the SWG manual recommendations ... see:
ABCs of Water Chemistry
Recommended Pool Chemicals
Water Balance for SWGs

You do need to raise the CYA, and use bleach to bump up the FC, but you do not need to raise the CH or the TA.

1 pound of CYA would have only added about 15ppm to your pool ... so that will not show up on the test yet.

Have you been using PoolMath?

 

[DirtYCreeKMemaw]

Yes....and that brought me to my question of what do I do first....lol

FC and CYA are all you need to adjust. Put the CYA in a sock and hang it in front of a return jet.

Ok..that's what I did b4...so according to the pool cal add 2 lbs & 11oz...and however much bleach it said. Simple enough! I can handle that...I was just unsure on which "levels" I should be following...So going forward I'll use what TFP says under the SWG. Which is way more in line with what my readings show. Happy camper now! I just over think it sometimes!

Thank you so much for your input! ..... side note...how long after all the stabilizer is dissolved b4 it will show up on the test? I don't want to wast the chemicals...

Once the CYA is out of the sock, it should show up on the test in a day or so. Just assume you are at your CYA target when determining your FC level.

OK! Thanks so much for the help!
