When to admit defeat and start over?

[BigDave]

Not failed, but maybe losing. Get back on it. Persistence is key.

So, given our new numbers above, is there anything else we need do but get the FC to 15 and keep cleaning the filter?

Couple of things:
1) 1 gallon of 8.25% bleach SHOULD add about 12ppm of FC to your pool
2) When you measure your FC and CC, use the 10ml line and not the 25ml line. You'll use up your reagents too fast and the .5 measure for each drop is more than accurate enough.
3) When measuring CYA do it the same way every time. I hold it at waist level and face into the sun. Then I spill the solution back into the squeeze bottle and do it again, at least once, sometimes twice, using the same solution until I'm satisfied I've gotten a good reading. The scale on the side is a log scale so halfway between 30 and 40 is NOT 35, it's less. Your guessing at "38" but it may be lower if it's not right on the "40" line.
4) If your FC is 3 and you add a gallon of 8.25% bleach to your pool you'll be (nominally) at 15.
5) You need to check and adjust your FC level at least 2x/day, preferably 3x until what you are fighting is dead. You CAN go a bit higher but may bleach the pool a bit.

Thanks, this helps a lot.
Will report back in a few days.
Hopefully with good news.

Only one tweak to the good advice Carl gave you. When you test CYA, you want the sun at your back.

Thanks, Watermom.

In order to get a definitive answer, I asked the Director of Education @ Taylor Technologies, Wayne Ivusich, and he was gracious enough to pass along this bit of information:

"the "correct" way to test for anything (not just CYA but for all the other tests, especially color-matching) is to NOT face the Sun. The Sun will alter you eyes' ability to match colors. The Sun should be behind you or on your shoulders. Never face the Sun. If it's an overcast day then it kinda doesn't matter!"

You might want to put that in a sticky as Taylor's Instruction Manual doesn't address it.

I don't know if we'll ever get our pool clear, but I'm certainly enjoying all the conversations about it.
There's some nice people in this business.

Honestly, if you're not clear yet, you may want to consider draining, refilling, and then following the SSR (http://pool9.net/ssr/)

I've ofter said in the past that pools are not that hard, but that they aren't forgiving, either. That's doubly true with the soft-side pools, like the Intex. With the seriously undersized pumps and filters that can just barely keep up with a normal, there's simply no extra capacity for cleaning a mess.

If you have a cartridge filter, do make sure you get the Unicel cartridges, before you start up. Those seem to make quite a bit of difference.
