Newbie needs help/advice

[poolgal]

Hi All
so we're changing from "pool store supplies" to the BBB method

Pool info- in ground concrete/plaster pool; 10,000 gals, in full sun (southern california)
this mornings readings:
FC - 0.4
CC - 0 (no visible change)
Ph - 7.2
alk - 110


any advice greatly appreciated, went out and bought borax and bleach today ready and willing to learn

thanks

You need to post CYA numbers for exact advice. For now, put about 3/4 gallon of bleach in the pool, slowly. Take about a minute to trickle it in. This should put your chlorine around 4ppm. When you find out your CYA level, that may be too low or just right, but it will keep it safe for now.

Also, it's probably a good idea to get a Calcium Hardness reading since you have a concrete pool. The range to be in is 200-400ppm.

Welcome to the forum. You'll learn a lot here.

How does your water look?

water looks fine, clear with light blueish tint

Don't have the CYA or calcium testing kit yet

stupid question alert: anywhere in particular I should put the bleach in the pool?

told you I was new to this!!!

I just pour it in the skimmer with the pump on and leave it on for several hours.

Or you can walk around the pool dribbling it in.

Or you can pour it slowly into the return stream.

But no matter what your CYA is, your FC at .4 is definitely too low. I would add a full gallon of bleach and get it up to 5.5 (about) for now.

But get those other tests!

Better still, get your own test kit and run the tests yourself.
