Yes I seem to need some advice. I apologize for bringing up a bromine question but I can't really find any other place to go. The pool was opened about three weeks ago. after being open about a week the pool went from a nice blue to green but clear water. I immediately suspected a lack of bromine. I emptied out the bromine canister myself and confirmed that water is at least flowing into the canister. I reloaded the canister with Bromine and then put some tablets in the skimmers and ran the pool continuously for a couple days. This seemed to restore the normal water color. Unfortunately at the time my new Taylor kit had not arrived so I was flying blind. This was on a sunday, the following thursday I had the water tested at Leslies, the results were Bromine 1 ppm, pH 8.0. TA 100 ppm, Dissolved Solids 700, calcium 200 ppm, and phosphates 1000 ppm. The pool company came and "inspected and flushed" the Bromine Cannister the following saturday, told us it was ok, and left a nice bill behind. My taylor kit came the same day and on Sunday (last sunday) I tested the water using the kit with the following results Bromine 0.5 ppm, pH 8.0, TA 160 ppm,calcium 280 ppm. I then tested again today and the Bromine is down even lower, i'm just guessing .25 or less ppm, everything else is the same as monday. Obviously there is something wrong, my question is is it definitely the delivery device for the Bromine that is not working (despite the pool company's claim that they checked it and it is fine) or could there be something going on chemically with the pool water. I'm starting to see a little black (I think) algae pop up which I've brushed and treated with polyquat. I'm just getting nervous that a full algae bloom is not far of given the low Bromine. I was hoping that Leslie's would give results for individual metals rather than TDS but I think i'm going to risk it and start shocking with choline to try to get the bromine levels back up. Any thoughts?

The pool is a 36,000 gallon in ground gunnite/plaster with DE filter. Test kit is Taylor K2006

Anyone know of a reputable pool company in Northeast MA?
