Question already. Checked the CYA shock chart to find out what my shock FC should be, and for my SWG it says to have a CYA of 60-80. My CYA is at 40 (45 at best). Do I have to adjust the CYA before I SLAM? pH just registered 7.2 so otherwise I'm ready to go.

Fabulous, thank you so much for your help. Turned the return down - I think it was aerating (there were bubbles breaking the surface). I usually conserve electric when and where I can as a general rule - it's on a timer, but it's been running since Thursday anyway. No worries there! I'll keep...

Hi, thanks for the link. Sorry for not being clear - I was in bright sunlight and did my due diligence (or at least tried) executing the test to get an accurate read; the pool, however, was not.

The CYA test was done at just as the pool went into complete shade. The pool gets about 6-7 hours of sunlight - today it was in direct sunlight about 4 hours. I'm in North Eastern Pennsylvania.

I'm getting the hang of it! Will add the MA tonight and start the SLaM in the morning when I can monitor levels. Should I have my return jet angled down to mix the MA? Should I then leave the filter run all night? And most importantly ... Can you swim during the SLAM?

The TF-100 test kit arrived and all tests have been completed! Here is the updated situation (with a +/- for operator error): FC - 3 CC - .5 TC - 3.5 CH - 250ppm TA - 150 CYA - 40 NaCl - 3800ppm pH - 7.5 SWG is still off. The water is a tad cloudy, but no green at all. I have continued...

Thank you - adding the second gallon of liquid chlorine and letting the filter run all night. The SWG is still being by-passed until we finish the shock - is this ok?

Thank you so much for your quick response! Just ordered the test kit. It's not due for delivery until next week - what can I do in the meantime? I have 4 gallons of liquid Chlorine on hand. I have been reading this site .... and reading ... and reading ... I'm am avid reader and a teacher and...

Greetings! I'm new to TFP, and I have to give major props to this site - it has saved me quite a few times! So thank you so very much!! I am having an algae issue and I can't seem to find answers for a few of the questions I have. I'm trying to piece all of this information together to fix...
