Need some advice on CYA, TA, & CH

[Judodad]

Using my TF-100 Test Kit here's my readings

FC = 5.5
CC = 0.5
CH = 350
TA = 50
CYA = 20
PH = 7.8

Sounds like I need to add stabilizer and I'd like to get my CH to 300. I've never had TA that low.
Thanks in advance for your help.

I agree with most of your assesment.

1. Raise TA to 100 using baking soda

2. Recheck pH...lower if 8.0 or above

3. Raise CYA to 50 ppm

Leave CH alone....it's fine and will slowly rise.

How does your water look?

5lbs of Baking Soda will raise the TA from 50-70. Pool math is your friend. http://www.troublefreepool.com/calc.html
I wouldn't worry about CH. I run my CH at 500.
I'd bump up the CYA to 75 or so about 8 lbs.

What's your salt at?

EDIT - I overlooked your SWG....bobodaclown is correct....CYA 75. Sorry!

Water is clear, salt is 3500. I was thinking the same thing after plugging it in to the pool math calculator but I wanted to make sure I wasn't overlooking something. Thanks for the advice guys!
