So, I'm not sure if this is the right section of the forum, but here goes....
I've been using Jack's Magic Blue as my sequestrant of choice. I'm using BBB with an LQ with my water chemistry maintained in the following range:
I use sequestrant because I filled the pool with my well water and use this same water (un softened) to replenish. I know that there is iron in the water, but don't know how much at this point....I plan to have my fill water and pool water tested at the PS for iron this weekend, if I can get over there. My question is this, are there less expensive sequestrants that will work just as well for my iron issue and that won't sequester my calcium?
