Hi Satt;

If you're not happy with it, then that's different. We need to work out a way to transition without making a mess, and without having your pool go through an unusable period. Since you have stains, we need to shift your pool into a stain-lifting mode, and then after we get the metal into solution (in the pool water), we take it all back out, but on the filter and not the sides of your pool. I think we can help you do this, and it won't be terribly hard or expensive, but it will require some attention to detail.

1. Go ahead and get the K2006. It is NOT the same, and you will need it. It's also NOT the same as the K2005, which is NOT what you need.
2. Tell me what tests you have in the BlueDevil -- we may be able to use it for some things. Is the chlorine test DPD (turns red) or OTO (turns yellow). We can use the OTO.
3. Make a list of chemicals you have -- if we can use any of them, let's do that, rather than buying new. (Also, it's usually the best way to dispose of them.) But, I need EXACT mfg and label names, and also any chemical ingredients listed.
4. Tell me what kind, and size of filter you have, and whether you normally use a time clock or run 24/7.
5. Does your pool have a deep end? How deep? (We need to calculate gallons.)
6. Are you swimming yet? If not, when do you want to start?
7. Do you have ANY equipment besides the pump, filter, and copper unit? If so, what?
8. What surface do you have in your pool - vinyl, fiberglass, plaster, Diamond brite, etc?
