How about brushing the pool sides and bottom during treatment? When and how often? Okay to use the SS brush?
I'm hoping some of the scale will begin lifting too. I only switched to BBB (minus the borax because of dogs drinking from pool) a couple of months ago. The scale was deposited in the past year prior to BBB, as I acid washed last fall. When doing the acid wash we didn't do the bottom too heavily as it was really thick there in some areas and I didn't want to cause any pitting in the areas that didn't have as much scale. I know from experience about pitting on horizontal surfaces (even slopes too) as I have one small pit on the top step from last years acid washing. The only way I could get the scale off of the steps without damaging the blue plaster was to use an angle grinder with a concrete disc. Took me a few hours to do the bottom step but didn't get the other two done due to an injury while doing the AW.
