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.

The theory is that if the phosphates are kept low then you can have
lower chlorine levels. When I first bought PR-10000 my phosphate levels
were off the charts, the test kit didn't go that high. One quart of
PR-10000 brought them down to zero and the algae problems went away. To
solve the problem with higher chlorine levels would have actually been
more expensive because it would require that I maintain a very high
chlorine level forever, or drain and refill. Phosphate reducers treat
the cause of the illness. Chlorine treats the symptoms of the illness.
