Another local pool store http://www.skybluepool.com/ sells Orenda
PR-10000 http://orendatech.com/products/pr-10000/ in bulk, you just
bring your own container. I bought a gallon of it for $125.

Yeah, I spoke to Ryan and he said he and his dad sell a lot of
that stuff. That store is the hardest place to find though, tucked
away in that parking lot above Vasona. I found them by accident
one day, searching for spare pool motor parts before I found "Bob".

However, it's my understanding that a phosphate remover isn't
necessary [in most cases] mainly because chlorine is enough to
keep algae in check and secondarily, because phosphate removal
comes at its own price.
