Copper in water - ok to use bleach?

[Sully]

You need to hold your Shock value (25 ppm) until the pool is crystal clear. Adding chlorine everyday, 2, or 3 times a day to maintain 25 ppm. After you pool is able to maintain chlorine level ( dropping 1 or 2 ppm a day is ok) you can let it drift down to 8 - 15 ppm and maintain it at the level, adding chlorine everyday as necessary. IF you maintain the pool at these levels, there is no need for a weekly shock.

You need to get a good drop-based test kit, (strips do not cut it) whether the 5 way HTH kit from Walmart or the kit through this site. 5 minutes a day for testing and adding bleach is all you will need.

OK, thanks for that explanation. I understand; except for one detail. My pool is crystal clear and has been all summer. I saw green algae on the skimmer last week, but I brush it every day and have not seen anymore since. I'll do as you say and keep a constant check on it.

Can we swim in a pool with 8-15 ppm chlorine?

Thanks again!

With a CYA that high, yes, you can swim in it--it would be the same as swimming in a pool with lower chlorine and CYA, proportionally.

Thanks, Janet! I wish the pool stores in my area had as good an understanding of CYA as you guys do. I appreciate the help!
