What if you don't have any way to vacuum without going to filter...are there any other solutions or procedures?

Hi, Jaime. You will not be able to use this product. You can use a traditional Pool Water Clarifier

What if I can't get all the phosfloc out of the pool? is it harmful to people?

A  Answered on 9/8/2016 by InyoPools Product Specialist Scott W.

I apologize for the delayed response. Yes, it is safe to swim with that in the water. If it is taking a while to collect it all up it is just because you had a lot of phosphates in the water and most time your filter can't handle it all at once so you will have to clean your filter multiple times until all of it clears up.
