The sheet drain method is tricky -- I need to get with Al and work up a guide to doing that, step by step. Do it wrong, and you can end up wasting a lot of water. Meanwhile:

#1 - Get a FAS-DPD testkit, if you don't have one, ASAP. Amazon link in my sig (wait a day, if the Amazon seller isn't "Amato Ind", other sellers sometimes ship the wrong kit.)

#2 - Buy some sodium bromide pool treatment:

and add a dose -- that will quickly create a free bromine residual that will kill algae. But it will increase your chlorine consumption, because bromine cannot be stabilized. Add 1/2 label dose, and wait 24 hours. Finish the does if the 1/2 dose is not enough.

#3 - Get a CHEAP OTO & phenol red test kit, and maintain DARK YELLOW chlorine levels.

#4 - Once you get the Taylor kit, maintain 10 ppm + the bromide.

. . . more later.
