What to adjust first?

[itodd]

I have my pool setup now. I've added chlorine and cynauric acid. This is my second year with the pool. Last year I set it up late in the summer and didn't get too much time with it.

Below are the results of my TF-100 testing kit for my 4600 gallon Ultra Frame Intex Pool with SWG and 2500 gallon/hr pump.

FC: 2.5
CC: 0.5
TC: 3.0
TA: 60
CH: 40
CYA: 70

PH: ??

The pH is below 6.8 so I know I need to get that up.

What do I focus on first??

I focused on getting my pH, FC, and CYA right first. Until CYA was where I wanted it, I of course was adding bleach each day as it lost it quick in the sunlight. That FC level is low for that CYA value too, so get FC up quick. Even though you have a SWG, you can still supplement with bleach. Did you see the table in Pool School, showing FC to CYA levels?

I'd get that pH back into range, then check again on the rest.

What FC level do you think I should be trying to reach?

PH first (soon!). After that raise FC, which is too low.

With CYA at 70, the normal FC range is 5 to 10.

I added some bleach and soda ash. I will recheck the levels tomorrow.

Okay here are the newest numbers:

FC: 4
CC: 0
TC: 4
TA: 90
CH: 60
CYA: 60

PH: closer to 6.8 than prior day.

Going to add more soda ash to get the pH up. Any other suggestions?

Here are the results of my latest test:

FC: 11
CC: 0.5
TC: 11.5
TA: 100
CH: 50
CYA: 60

PH: 7.5

Any suggestions or are my levels good at this point? I realize the chlorine is high but that will drop. Do I need to add some more cynauric acid??

For your SWG your CYA level sound be in the 70-80 range.

What's the salt reading? If you're chlorinating by jug, CYA is actually a bit high. If you're using the SWG, and it's been at least a week since you added CYA, then you need a teensy bit more.

The salt reading is 3130. I was thinking I needed to increase the CYA a little. I'm always a little iffy when doing the CYA test (do I see the dot or do I not see the dot is always the question). The CYA has been in for a week now. I'm chlorinating with the SWG now. I started with bleach but now just the SWG. I will test the CYA again and then add some if I get 60 (using the pool calculator to determine how much).
