If your buying if from a pool supplier out of a big tank it’s all the same.
@florida_condo_cleani Do you always use 50/50 on tile? I got tired of hitting the same areas 10 times before they came clean. I’ve bumped up the strength significantly over the years.
50/50 is the max we use more often it’s 60/40 60 water and 40 chem. You shouldn’t have to do more than one coat and then some touch up . On most roofs . You probably need to find a different chem supplier. Most small pool stores don’t go through chem fast enough for it to stay fresh . If they get less than one shipment a week find another.
The store I use has so much traffic they have 7 chlorine stations. They definitely blow through some SH. It’s 10.5% though, maybe that’s an issue. All the pool stores around me are the same.
I cant imagine even 4% needed more than 2 passes
They are no good for roof cleaning. Only walking on dry metal roof
Not sure if y’all have this supplier but in Texas we ABC supplies and they distribute them there
