The TF100 is a modified K2006, modeled after the PS230 I used to sell. It's sold by another pool website. We recommend the straight Taylor kits. Link to the info page is in my blue signature block. It's very common for pool store test results to be all over the place.

Sounds like you've got a resurgent algae problem, and your SWCG can't keep up -- which is pretty typical.

+ Turn the SWCG off, and began dosing with 3 gallons of plain 8.25% bleach each evening. Brush after dosing, starting the 2nd evening.

+ Purchase a cheap OTO/phenol red kit, like these Walmart kits: #1 (preferred) #2

+ Test the pH and chlorine BEFORE adding the PM bleach dose. Skip if the chlorine level is DARK yellow to ORANGE. Double the dose if the chlorine level is very light yellow to clear.

+ Order the K2006 and report test levels when you have them.
