New Guy From New Orleans Area!

Hope you get to feeling better soon! Get that CYA up asap. It could take a week to show up on your test so do not test it immediately. Add about 50-60% of what is called for and test in about 5-7 days. Then run the numbers again on the pool calc and add the final amount and test again after a week.
 
Well back to the pool!

So the 17th I added 90oz of 8.25% and 64oz of CYA.

It actually called for 80oz of CYA, all I had was 64oz.

On the 18th I got another 4lb jug of CYA and added another pound. It also called for 194oz of baking soda. That just seamed like a lot so I only added 64oz.

Today the 19th I did some testing again

4-19-15 Time:1545 Pool Temp:78*
pH = 7.2
FC = 5
CC = Less than .5
TC = Adding FC & CC = <5.5
CH = 225
TA = 60
CYA = 40-50 At 50 I could still see it but it was cloudy, at 40 I couldn't see it at all.

Pool Math says to add 17oz of washing soda to raise pH but it also says to add 141oz of Baking Soda to increase TA but doesn't Baking Soda also raise pH?

CH appears to be dropping off with all this rain we been having. Is that ok?

Go ahead and add more baking soda. You pH won't go up. Its actually sitting pretty right now. Once you get your TA in line with the baking soda, your pH will become stable n not drift wildly below 7.2.

And for a fun little tidbit you may or may not know... The pucks that add CYA, will also make your pH drop because it's acidic.

So the 19th I added 8Lbs of Baking Soda and let the pump run all night. Yesterday I didn't do a full round of test just a Yellow and Red Chlorine and pH thing. Chlorine looked to be about 4-5 and pH was 7.2.

Today I did a quick test on a few things

Water Temp 78*
FC = 2.5
CC = <.5
TC = <3?
TA = 110
CYA = Didnt Test
CH = Didn't Test

Added 34oz of 8.25% Bleach and that's it! It seams that my Chlorine is lasting a little longer than what I had been reading it should. Does that me that with my CYA at the correct level the sun isn't burning it and if there isn't anything to kill it's lasting longer?

It's also said that I don't need to do a Chlorine drop test every day. How else am I going to know what to add if I don't know an exact number. The yellow color drops seam to be more of a judgment call and almost a guess.

I use my fas DpD test more than the yellow drop test because of accuracy. It would not hurt you to do it either. I personally like that there is no guessing. I probably use the yellow test less the 5 times a swim season.

Yes, that is what it means.
 
Well I must say that this isn't so bad at all after actually doing this method for a few weeks. Now I just need to learn what my pool wants and when its wants it and that will make it even easier.

In the beginning when you are getting the pool straight it seams like you go through a good bit of testing products. Can you buy the testing products by themselves without purchasing the entire kit? If so where do I get them from?

Im sure as I continue to do this I will have other questions so I appreciate all the help from you guys and gals!

Thanks.

By the end of summer if not sooner, you'll be able to predict with accuracy what your pool needs before you even test. You're probably getting pretty comfortable with that already. Good job man! You may encounter the problem of people not believing you when you tell them how little you do to keep your pool so nice.
 
Hows is everybody doing?

Just a little update and a few more questions.

4-24-15
I did not test the pool at all but did add 16oz of 8.25% Bleach due to expected rain. It only rained a tiny bit.

4-25-15
Rain hard for a few hours

4-26-15
Did a complete round of testing.

Time = 1400
Temp = 77*
pH = 7.8
FC = 2.25
CC = Less Than .5
TC = Less Than 2.75
CH = 200
TA = 100
CYA = 39

Once I got to work I reentered the test results into PoolMath again to confirm I did everything correctly and it turns out I didn't. I put 2.5 for FC when it should have been 2.25. I will add the bleach(4oz) I shorted it once I get off in the morning.

I also had a judgment call on the CYA, it was between 36-40. So in PoolMath i put 39. It said to add 2oz of CYA. I just put 38 in PoolMath and it says 4oz. If its a judgment call, will 2-3oz not enough CYA or 2-3oz to much CYA better? When testing CYA do i make it completely impossible to see the black dot or to the point of only seeing a slight shadow of the dot ok?

pH seamed to have climbed up some to 7.8(wife thinks it may be closer to 8) is this due to the rain? PoolMath says to add 14oz of 31.45% - 20% Baume' Mariatic Acid im assuming this is to lower the pH. Is it needed or a few days without rain will lower it, we don't plan to swim in the pool until maybe next weekend.

The CH also seams to be dropping off, PoolMath says to add 133oz of calcium chloride. IIRC it was said that CH isn't important in a vinyl liner pool.

If it rains. to lower the water level will running the pump to waste, back flush the filter? I don't believe it does i just want to make sure.

Call your Cya 40, and round to the nearest 10 up if you think its between numbers.

Don't worry about the CH. It's perfect where it is in Your pool. Being its vinyl/AG, it will be ok. If I recall, you had some Cal-Hypo on hand. You can use that some for Chlorine and it will add some CH for you.

Any rain influenced pH came from aeration, and your TA. Adjust pH accordingly, don't focus on TA.

Get the FC UP as a priority when you run through testing. This, and pH afterward should always be your focus.
 
Ok. First, how are you getting 2.25 fc? That's very precise unless it's an average of tests. Second, why are you keeping your fc below the bare minimum? If cya is 39, you should target 5 and be at 3fc for the minimum. Your 4oz shot glass of bleach is still gonna leave you .5 ppm below the minimum. On the cya test, the dot completely disappears at the correct reading. Your ph climbed because of aeration from the rain. It won't go down on its own. Calcium is not important for a vinyl pool. If you set the valve to waste, it bypasses the filter.

Call your Cya 40, and round to the nearest 10 up if you think its between numbers. Ok well I already added 2oz and will keep it where its at. I wont add the other 2oz tomorrow. Thanks

Don't worry about the CH. It's perfect where it is in Your pool. Being its vinyl/AG, it will be ok. If I recall, you had some Cal-Hypo on hand. You can use that some for Chlorine and it will add some CH for you. The range from what I have read is 0-350 and mines at a 200. If you saying not to worry about it why would I need to put Cal-Hypo in it? At what level should I throw some Cal-Hypo in it?

Get the FC UP as a priority when you run through testing. This, and pH afterward should always be your focus. As soon and I finished testing I put 36oz of 8.25% Bleach in it.

Ok. First, how are you getting 2.25 fc? That's very precise unless it's an average of tests.
At 4 drops of R-871 the sample was clearish with a red tint, at 5 drops it was crystal clear so I called it 4.5 drops

Second, why are you keeping your fc below the bare minimum? If cya is 39, you should target 5 and be at 3fc for the minimum. Your 4oz shot glass of bleach is still gonna leave you .5 ppm below the minimum.
I am using PoolMath to tell me what I need to add to the pool. PoolMath said target is 4 and told me to put 40oz of 8.25% Bleach with my FC level at 2.25. As I said above I accidently put 2.5 in as my FC level and PoolMath told me to put 34oz of 8.25% Bleach, I put a 36oz in it. When I noticed this mistake I changed the input on PoolMath and it said to add 40oz not 34oz. So tomorrow when I get off work I was going to add the 4oz of 8.25% Bleach I shorted it today.

On the cya test, the dot completely disappears at the correct reading. Thanks

Your ph climbed because of aeration from the rain. It won't go down on its own. Thanks, I will add the acid in the morning!
