Acid treatment, but no circulate

Evan, would that be like Jack's Pink Stuff? They have so many products, it's confusing...

Let me back peddle a little bit. I finally did the the vitamin C test correctly this time, and it did in fact remove the staining after about 10-15 minutes. This was a relief, as the staining is fairly light, but does cover probably 85% of the pool. This "epiphany" reminded me of the first year of the pool, the PB had to come out and clear a clogged drain (sponge left from construction). His weight (diving) belt had a tear in it---about 3 days later I noticed little balls in my pool, that left behind red rust stains. Could this have been the source of the iron? We're on city water, and the quality seems to be quite good...
