Chemical Help

I have an old ammonia test kit and it showed 1ppm in my pool water. I just tested chlorine several hours after adding 2 lbs of old shock I had, several pucks in the skimmer and 4 gal of bleach yielded FC of 14 and surprising CC of 2.
I double checked it in another area of the pool and got FC 13 and CC 3. Does that sound right? I am new to this type of testing but following the procedure for 10ml.

Where in the pool is the best to get the water sample?

I wouldn't worry about it. There are only two options: you can drain, clean and refill; or you can chlorinate till it's gone. Unless you are asking the question, "Should I drain the pool?", the question, "Exactly how much ammonia is there?" isn't really relevant.

A variation between FC=13 and FC=14 is certainly within the error range of that test . . . so it may not be an actual difference. But, depending on circulation patterns in your pool, it may not be an error. In that case, the 'best place' to get a sample, depends on which part of the pool you want to measure!

Are you thinking about draining and refilling? (Keep in mind, this is not really an option with a vinyl pool.) If not, just chlorinate till it's gone.

Mine is a vinyl pool and the liner is about 6 years old. I would hope not to drain now, although we will need a liner in the next few years because ours is wrinkled in the bottom of the shallow end and not looking so great in the deep end from shock lying at the bottom.

A quick check this morning had a FC of 10.5 but CC was up to 6 again. Does that sound right? Am I going in the right direction?? Would it be cost effective to do the liner now?? Cost of refill is $250 plus for me.

New liner installed can go over $1,000 . . . and this is NOT the best time of year to go after one. The pool business has picked up, compared to last year, so the guys that didn't go belly up 2 years ago, are really busy. If you go after a new liner now, you'll be at the bottom of the list, and might not swim till July. Plus, when you pull a liner, there are often OTHER repairs that have to be done.

If you're OK with all that, go for it. Otherwise, keep chlorinating. But, do raise the pH with borax.

If you can wait until January/February to buy the new liner, the places (at least down here) often offer really good discounts on"last year's models" because the new liner patterns are published around March. I don't know if it's possible to install one in January in your climate, but you might could at least get the contract signed and get on the list for when the weather warms up--and save yourself some money that way. My new (discounted model) liner cost around $3K a couple of years ago, installed.

FC went down and CC went up to 5 FCC and 8cc. I am putting in 3 gal of beach at night and morning. I will check levels later today and will post.

Sounds pretty normal, for an ammonia filled pool. But, you'd be better off putting in 6 gallons at night, and skipping the AM dose. That way, all the chlorine you lose, will be lost converting ammonia, rather than losing some to sunlight.
