Greetings to this knowledgeable community.
Thank you in advance for all your help, I have gained a great deal of knowledge in the past week from lurking and using the Pool School page.
In a couple months I will be moving into a house that has an IG, indoor plaster pool (further described in my signature) I do not yet know any of the chemical levels of the water, or the exact sizes of pumps or filters that are installed.
I do know, however, that there is a "Caribbean Clear" unit installed on the pool which appears to be a copper ion generator. I have read of SWCG systems, bromide, Bacquacil, ozone and other systems, but have come across very little information on these copper ion generator units. (1)What is the general opinion of these units today? Pros/Cons compared to other types of systems? Any input on whether I should try to get it working again or just go with chlorine, or replace it with a SWCG, or any combination of the above? Any problems I should suspect that the copper ion generator could have caused?
(2)SWCG looks very interesting to me, but I am skeptical about whether or not this will cause increased corrosion in the pool. With plaster and concrete being porous, what kind of damage could this possibly do to the rebar in the pool walls? Or the heat exchanger?
(3)Currently there is some green algae on the bottom of the pool (maybe 3 feet square) is it possible to get rid of this by shocking the pool? Would it be best to drain the pool? Ideally I would like to drain the pool and scrub but I am not sure how the well will hold up to refilling the pool.
(4)The pool is in its own room detached from the house, it has its own HVAC system, a standard roof with two small skylights, but the walls are all glass. Will I be okay not using a chlorine stabilizer?
Thanks again for all the help!
