Stuck with Caribbean Clear

[dont1ab]

We have an inground plaster pool, 40,000 gallons (painted surface) that has a Caribbean Clear system. I am trying to convince my husband that we need to use chlorine regularly - he insists that we are supposed to "shock" the pool with Oxone and only need to put one gallon of bleach a week in the pool.

Currently the water is tinged green and a bit cloudy. I keep fighting rising pH - we need to add muriatic acid nearly every 3 days. Every time we add chlorine, the green water gets closer to the blue it should be, but it doesn't last...

The numbers:
pH 8.0+
TA 100
CH 280
Chlorine (all tests) 0
CYA 0
Copper 0.2

Added 3/4 gal of muriatic acid and 2.5 gal of 12% chlorine this afternoon just before the storms.

Thank you for the forum and for your advice :)

With copper, you'd better get your pH down, sooner rather than later. Also adding a lot of chlorine can cause the copper to come out and stain things. The only thing I know that you can safely use to help is polyquat algaecide (http://www.poolsolutions.com/gd/polyquat.html) plus low levels of copper.

Of course, your pool still won't be sanitized. (I guess you know we don't recommend coppper-based 'sanitation' systems?)

I am not a fan of the copper system, my husband bought the "snake oil" years ago - I can't convince him to forget it, however we are beginning to use chlorine to measurable levels :) Thanks for the advice on the polyquat, will give it a try!

I am hoping in the fall or spring to re-plumb our pump system to get rid of a few leaks, and maybe that copper boondoggle in the process...
