Clear, but no chlorine???

Absolutely don't know how to do that!

Is there a valve for the "extra" line? If so, we can tell you how.

[mary jo]

i was never told about an extra valve- was told not to worry about the extra hole…..I have 3 "T" valves. I turn off 2 when vacuuming.
(I probably need to review pool terminology)

[FormerBromineUser]

When vacuuming, you leave on the skimmer valve. You apparently close the main drain. What changes when you close the third one?

As long as it has pool water flowing through it, I wouldn't worry about it.

So continue to keep the pool at shock level- 30- and see what happens to the CC.

btw: the skimmers again have a very thin line of sticky, greasy, black stuff around the waterline. I was going to wet a cloth with chlorine and wipe. Never had this before last Sunday.

The shock seems to be working, I wouldn't stop now. Like PoolDoc said - clean that goo off while you can.

I occasionally get the same black goo in the skimmers. I just clean it off when I notice it. It's been happening for years, but I've never notice a negative impact on the pool from it.
