Why is this so much more expensive on Amazon than anywhere else?

Actually it's almost $6 cheaper than the pool store I go to.

Does this help with Well water issues?

This will help with cloudy water in a swimming pool. If you used well water to fill your pool there are many things go that could be in your water from minerals to metals that could cause issues when you simply adding chemicals. If you are struggling with well water in a pool I would suggest finding a local bioguard dealer and bring in a water sample for testing. If you are struggling with water in a well, this is not the product for you.

How long must you run pump/filter after adding this to the water?

I have a 35,000gal in ground pool and use this product about once a week. I have the pump running 24/7 to filter, chlorinate and operate the skimmer. I also have a separate hot tub that may be what you are asking about, as far as that, a regular couple of cycles should be fine. Like 15mins to 30mins.

Can this be used with baquacil?

Baquacil is biguanide product and after lots of research this product does work with it. I have a baquacil pool and it does work as advertised.
