Yes Bonnie, I agree it has seemed that every time we think we're getting close another big AZ dust storm will blow in, and start sucking up all your chlorine. Only this time that AZ dust has been hidden algae.
.
I saw another comment in a post yesterday where they kept getting close to passing OCLT only to again not pass over and over, and their problem was again hidden algae behind their light. I've seen this multiple times with ladders too. Once they got the algae cleaned out, they passed OCLT the same night. It's crazy how just a little hidden algae can cause a person so many problems.
That's why it's so important to focus on all those little spots because more often then not that's where the problem will be. (I know you all don't have a ladder, or removable steps, but anywhere that stuff can hide in i.e. lights, returns, skimmers, removable steps, ladders, etc. it certainly will hide in there, and set up home, IF the chlorine level has ever been allowed to drop below the minimum for their CYA level to allow it to grow.
There's no doubt in my mind that you will get yours cleaned out too. Also when he's got the hose in there tell him to spray around every opening in the pool that he sees that there could be algae hiding in ie) return, drains, skimmer, lights, etc. If it's hiding in one spot it could definitely be hiding in several.
Just stick with it, and I promise you it will get out of there. I'm so proud of you guys though. You and Rusty are working so hard, and have done, and are doing an excellent job at trying to eliminate this problem. Our goal is for you to be able to enjoy your pool, and be able to easily, and quickly Maintain it, without having to deal with recurring algae over, and over again, and I know that's your goal as well.
Once it's all cleaned out Maintaining your chlorine levels 1-2ppm above the minimum for your CYA level, At all times, never allowing it to drop below Minimum, will be the key to helping prevent a reoccurrence in the future.

Keep up the great job. Have a wonderful day.
