First time Slam today.

[Mdragger88]

I added in 10ppm more CYA, should I add any more shock?

You’re still at slam level for 30ppm cya so check fc again in a couple hours & replenish as necessary to maintain 12ppm fc

Seems we're getting testing and water balance in order for now. How's color and clarity coming along? This pool has a party to attend!

Be careful about adding your stabilizer. Give it a day or two before adding more, it can be deceptive in how long it takes to show up on with the test.

In case no one else has mentioned, if you can see the bottom and your FC is not over SLAM level, you can get in.

I just did another test.

FC is still 12.5
TC is still .5
CYA still has a visible dot, but right at 20ppm it starts to disappear.

My pool is blue, it's just a tad cloudy and a little dirty from whatever my net can't capture on the surface. I'm still waiting on my skimmer.

Make sure you are testing CYA properly:

Do test at midday or near abouts with sun behind you. Pour solution to one line then GLANCE into the tube. You can start by pouring to a line that is well over what you expect.

When you see the dot at a GLANCE, pour to the next line. Glance in. Still see dot easily? Pour to next line.

When the dot is not visible at a lightning quick glance, that is your CYA. There may be a slight whisper of the dot, but you can call it there. If you stare into the tube, your mind will fill in that dot. Hence my all-caps GLANCE.

From this point on, when you do test CYA, do it under the same conditions. If you vary the time of day, or do when it is cloudy, you are going to have different results.

the phenol red ph test is invalid at fc levels over 10ppm so disregard it.

Curious, say my cya is 80 (SWG) and I wanna keep it at the high end so 11 FC
How would one test the daily pH?

Do so when it falls to 10ppm. Or use a ph meter. These should be checked against the phenol red test regularly though.

Thanks I'll remember that for my next test. It seems like my finish line is on the horizon.

 

[mg83]

FC 12.5
CC .5 It's clear with a TINY tint of pink.
CYA 25

CYA 25

25 counts as 30 for chlorination purposes (for cya always round up if inbetween two lines)
Keep maintaining 12ppm fc

What numbers should I be looking for before we jump in?

You can get in the pool when you are able to see the bottom and FC is above minimum and at or below SLAM for your CYA (so for 30 CYA 2 up to and including 12FC). For comfort, keep the pH in the 7s.

 

[mg83]

My tests are incredibly consistent.

FC 12.5
CC .5
CYA 30
pH 7.34

I didn't do the CH or TA test. I have nothing on hand that would increase either.

I can see the bottom clear enough to make out the wrinkles. Still a little cloudy though, like after rain.

 

[bobloblaw42]

Seems safe to get in then. Since you're in a SLAM and water is still cloudy, you can swim but test and top up FC after. You may just be waiting on the sand filter to pull out dead algae and other debris.

If you're looking to speed things up, you can consider adding pool grade DE to your filter.

Add DE to a Sand Filter

A clean pool filter will increase the efficiency of your pool! ... your filter are to backwash it, clean the manifolds and grids, and add new DE.

I wish pictures could show it better. It's more of a haze on the top. My skimmer should be in tomorrow, and our pollen is just ridiculous this season. But this is music to my ears!
