Hi -- I've been reading the site for the past few weeks and learning a great deal. Ordered my TF-100 test kit today.
I just noticed this past weekend a hint green murkiness in the pool. I've recently added the Bio-Active CYA reducer about 2 weeks ago to help get the CYA down. It was about 130 ppm and now reads 100 ppm.
Hopefully the test comes soon. In the meantime, I plan on draining the pool down a 1/3 or so and filling with fresh water to help drop the CYA prior to doing a SLAM.
