Numbers after partial drain and refill

[dravenone]

Below are my previous numbers and required a partial drain and fill.
Before drain and fill
FC 5
CC 0.5
PH 7.2
TA 100
CH 550
CYA 100+ Still don't reach first line on test

I guesstimate I changed about 75%, which I still feel guilty about being in drought town CA. So now I present my new numbers for your review.......
After drain and fill
FC 2.5 (floaters are out of the pool and I added 6% bleach! But I need to double for my CYA)
CC 0
PH 7.5
TA 130
CH 300
CYA 70 (looks like I had a ton of this stuff)

Great, your numbers are looking much better!

A CYA of 70 is acceptable, even though we recommend getting it down to 50 if you can. The only thing you need to do is raise your FC level, as you already know.

Do you backwash your filter? You'll see that 70 slowly drop over the year....I ran with 70 one season and it slowly came down from water replacement.

Make sure you keep that FC up at the proper level!

Great job

I could not have done it without everyone's advice and all the great info on this site. Now I will be going SWG in a couple weeks, I believe my CYA of 70 should be good for salt?

Here's an article on water balance for SWGs if you haven't already seen it:
