Starting up and trying to avoid the pool stores

[AnnaK]

Welcome to the forum!

What you have on the bottom of the pool may not be algae but just plain dust and dirt. I have that in my pool as well and I know I don't have algae. I vacuum it up now and then.

I'm no expert with SWCG systems but I do know that each has its own CYA requirements. Please check the manual for yours and see what the recommended level is. Did you add granular CYA or liquid? If liquid, the test is probably close to actual. Granular takes a few days to fully go into solution.

Your pH is in range. I like mine at 7.5 but anything between 7.2 and 7.8 is fine.

The alkalinity is very high. What have you added to the water to get it to those levels?

Are you doing your own testing? If so, what test kit do you use?

The pool is fine for the kids to swim in. If they're splashy kids and you have to top the pool off with new water frequently then your alk will drop over time. You're looking for something between 80 - 120.
