Dear TFP community--
Forgive me, but I feel as though I need to coin a new name for the type of algae I have in my pool. It's often said that cockroaches would be the only thing to survive nuclear war, so I'm going with that for now. Last year was my 1st year of pool ownership and I didn't find TFP until about 6 or 7 weeks into the season. As a result my CYA got way out of control from using chlorine pucks - I battled problems all summer, but attributed most of them to the high CYA level. This year I was optimistic, I *thought* I knew what I was doing after reading pool school cover to cover and scouring these forums. After opening the pool, clearing out the debris, and balancing the pH (7.2), TA (70), and CH (100) I brought the CYA up to an even 30 and began the SLAM'ing process (FC = 12). I SLAM'ed & brushed & SLAM'ed & brushed for 2 weeks - there was improvement but every morning there were fresh streaks of algae in certain sections of the pool. The FC would hold overnight, and we had less than .25 CC, and had suspicions of mustard algae last year, so we decided to take it up to the mustard algae shock level (FC = 20). We held the FC at that level for 48 hours and brushed everywhere that we could brush, took the light out, scrubbed the ladders - we genuinely tried to live the spirit of the mustard algae pool school process. Thursday night, after 48 hours at FC=20 we began to let it drop back down, as it had turned pure blue cloudy and wasn't consuming any FC. I thought that we were simply into the "be patient and let the filter work" stage - then I looked at the pool this am - and there are again streaks of algae in the sections of the pool where it normally collects. I hung my head absolutely defeated by cockroach algae.
Any advice (including where to get some plutonium!) would be greatly appreciated.

FC = 14
CC < .25
pH = 7.5
