I was typing this as chem geek and you were typing. The absolute best thing you can do for your pool is to get that expensive, "sure to give you stains" Nature 2 out of your system. I used ionization from late 80's until last year. I'm very "intimate" with the dreaded copper staining and probably the only time my pool was really safe was after the weekly shocking dose of chlorine. I suppose that one could avoid eventual copper staining but the challenges keeping system just at the right balance to avoid the stains are immense. The long, slow EXPENSIVE treatment I'm doing on my pool now is partially for copper staining. The copper stains were deposited from summer of 08 through summer of 09 after a major acid wash in 08. They may never totally go away and this 14 year old, but still in good shape (except for the copper stains) plaster has had three acid washes and I'm not willing to risk the damage another acid wash would cause.ethany said:I read that keeping the ph lower will help with staining (7.0-7.2) I have a saltwater gen. and the BBB method for swg says to keep ph between 7.5-7.6
If I kept it on the low side,would it damage the swg or other equip.?
That's encouraging. Be sure to test out different areas of staining. Vit C tabs didn't do anything on my copper stains but most of them were under white scale stained by iron and as the scale is releasing the stains are becoming more evident. My plaster is blue so it is easy to see the blue plaster emerge as the scale lifts. Although my staining is too spread and extensive to spot treat I ordered five lbs of Jack's Stain and Scale treatment. I'm going to put some in a sock and hang down at a staining point. If it does anything I might use the Jack's Stain and Scale treatment once the weather cools down and the dogs aren't as interested in swimming. That's when I did the AA treatment last year but the water was so cool it took a lot longer than usual.ethany said:I have spot treated with a vitamin c tablet and it instantaneously dissolved the stain,so I am hoping it would work for the rest of the pool.
I see. You have a very small window. If your water temps are pretty high now it may only take a day or two but then you have to up the chlorine slowly or else the metals will fall back out. Don't skimp on sequestrant and algaecide but be sure that the algaecide does not have any copper it it; many do.ethany said:I live in NJ and it is still very warm here, last couple days it cooled down to high 70s to low 80s. Next week it will be in the high 80s so I hope I can complete the treatment before it gets too hot.
I need to close the pool early this year because I have to plant grass seed and since the cover needs to be spread out across the yard it becomes a problem.
Is the Duoclear not able to be pressurized with the mineral cartridge removed? That's what you seem to be indicating. That's how the Nature 2 Express functions.chem geek said:Since the cartridge is apparently "replaceable", why not just remove it? Why wait until it gets used up since it will just continue to add metal ions to the water increasing the risk of staining.
