Overwhelmed

It's not too high... Just a little higher than your normal operating range, but there is no harm in that. It will come down on its own as the fc is used to keep the water sanitized. It looks like you are still testing chlorine with the 25ml sample instead of the 10ml sample. This is your choice, but you will use up your reagents much more quickly, and the accuracy of the 10ml sample is plenty good for our purposes here.

As for cc, uncovering the pool will help eliminate it... This allows the uv from the sun to break it down and the gasses to escape the water. However, 0.4 is acceptable. If it goes above 0.5 you should shock the pool (assuming it has been uncovered).

Yup! That's right. Readings look good!

You have a vinyl pool and your Calcium Hardness is SUPER low--which means if you want to use Cal-Hypo to chlorinate, you won't have to worry about it going too high for a long, long time.
In fact, unless you use Cal-Hypo a lot, I wouldn't bother testing Calcium Hardness again until you close the pool.

Do NOT add calcium just to add calcium or because the pool store guy tells you that you "need it". You don't. Low calcium is harmless in a vinyl pool.

Otherwise, other than using the 25ml instead of the 10ml line to test chlorine levels, you look like you are doing fine.

I agree that your numbers look good. My only comment is that if you find, once the heat of summer gets here, that you are having trouble keeping chlorine in the pool through a hot sunny day that you might want to bump your CYA up some. You may not need to but just keep it in mind if you start ending up with your chlorine level below the needed minimum (per the Best Guess Chlorine Chart) at day's end.

Good job!

Looks like you're not so Overwhelmed any more. Congrats! Have fun!

Yesterdays readings are:

FC 5 ppm
CC 1 ppm
Alkalinity 7.6 pH
CYA 42

Please advise.

Also, someone stated raising stabilizer. How do I raise that again?

[PoolDoc]

40 ppm CYA is OK.

5 ppm FC is OK. 1 ppm CC is probably a testing error, unless you are 'smelling' the pool.

You can raise CYA by dissolving cyanuric acid into the pool -- a sock works well for soft side pools -- or by using dichlor or trichlor, which add almost a ppm of CYA for every ppm of chlorine.

So should I add just one "dose" of dichlor? or two? and should I ALWAYS do equal amounts of BORAX?
