Hi all. In using bioguard strip kwik to clean our sand filter, a little got into the pool and the label on the bottle says NOT to get it in the pool. It wasn't much and a little foaming happened. I added clarifyer and put sparkle up in the filter to try to get it out. Seems to be working. My question is, "Is the pool safe to use"? Surely a pool chemical wouldn't be a health hazard would it?
