Thanks for the replies. I think I sent the wrong link for the bromine tablets. I am 99% sure that it was brominating tablets (at walmart). The link I sent looks similar, but I was looking for bromine specifically and Im really pretty sure thats what I bought and put in the pool (x3). Thanks for looking up my pool, its cool(and sort of creepy at the same time) you can do that on google maps (that picture was taken the day of my birthday last year). I do have steps in the lower left corner of the pool in the shallow end. does that effect if I can drain down to the deep end?

So Im pretty sure it was bromine tablets. So my options are try a foamy algaecide and maybe something like yellow out. I found pink treat which seems to be just really bromine. http://www.swimpool.com/PinkPoolAlgae-pinktreat.htm. We also have been having to add water every week because its been so hot. If I had to add it up its probably been maybe 2ft of water loss that may have brought the cya down some (havn't checked it recently)
