First test after install and fill a cloudy

[Jeff_O]

This site and forum is great, glad to be on it!

First test results after install and fill:
FC 7.0
pH 6.8
TA 20
CH 150
CYA 20
Temp 70F

I need to raise the pH, TA, and CYA up. I'm running the pump. The water is cloudy, so I'm not sure what to do next?

To be clear, this is a completely fresh fill? When did you fill it?

I started Wednesday 4/26 and it was full Friday 4/29. To clarify, this is my first full test. I did a quick FC and CYA test Friday neither registered. Added 2 gallons of 10% chlorinated bleach and 2 lbs of stabilizer then.

Ok, you want to get the CYA up in range. And use baking soda to raise the TA up to around 70ppm and then recheck the pH

 

[Jeff_O]

Ok, just tested after adding baking soda and stabilizer yesterday.

FC 4
pH 7.2
TA 80
CH n/a
CYA 40
temp 68

I'm running the pump and seems to be a little clearer today. I'll let it run overnight and check tomorrow to see how it looks. Am I missing anything?

Are you testing the CC? It is a little strange that the water is cloudy from a fresh feel. I might be inclined to raise the FC up to about 10 part per million and do the oclt test

Did you backwash the sand filter (if you have one)after installing? That could be the source of the cloudiness together with the plaster dust!

I haven't tested the CC yet. I will do that and see where it lands.

I do have a sand filter and I didn't backwash it at start up. I started it up on the filter setting. When I did that it blew a cloud of sand into the pool. There is definitely sand on the pool floor that needs to be vacuumed up. Perhaps it's getting stirred up and the source of the cloudiness?

Ah, well there you go. Sounds like dust from the sand

You can add son DE to the Sand Filter to make it clear a little bit faster, just follow the instructions.
