Clear, but no chlorine???

Can you reduce the flow to your returns and increase the flow at this extra line? If so, do it for an hour or so to really force the shock level water in there. You would do the same thing for other water features: fountains, slides, etc. periodically, and especially at high CL levels.

Absolutely don't know how to do that!

[FormerBromineUser]

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?

[BigDave]

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.
