Watermom - I'm really, REALLY, new to this testing stuff, so please bear with me (after you finish laughing).

I started this morning at 7 am; I vacuumed then backwashed; I added 1 quart of bleach which resulted in the following levels: FC - 5; TC - 5; CC - 0; and pH 7.8.

At 2:30 I added another quart of bleach and got the same levels.

The little measuring container has two ports; one labeled Cl Br, and the other labeled pH.

The Cl - Br side looks like this:

Cl Br
5 10
3 6
2 4
1 2
.5 1

The pH side:

pH
8.2
7.8
7.5
7.2
6.8

My question is: How do I measure 10pmm and 20pmm if it's not marked on my container? The kit I got from Leslie Pools cost $47. Is there another kind of measuring container with higher levels on it? Am I making any sense?

Thanks for your patience...perhaps we should move my posts to kiddy/remedial?
