I tried adding CYA to the skimmer, and it bogged down my system. My CYA level was very low, and my pool is roughly 17k-18k gal.

It's 6 days now, and it's still not all dissolved, it keeps returning to my pool, but less and less each time I push it down the main drain.

I took a reading yesterday (after 5 days) and it's approx CYA = 30, maybe less. The sample got VERY cloudy, but I still thought I could see the dot just a little bit.

FC and TC = 5.5 (I added 1.4 gal of bleach today, and tested 3-4hrs later, which is enough time for my pool to turn over, or very close).

pH = 7.4
TA = 70 (gotta get some baking soda)

The water is otherwise fantastic. Have been swimming and enjoying it. Occasionally I'll see tiny hint of green in one or two spots on the wall just below the surface, but it brushes right off.

So assuming those numbers are right:

How much more CYA do I need to put in (if any) and:

How much bleach or cal hypo should I use as a chlorinator and HOW OFTEN?
