Hi this is my first post here: great site! Just used my new tf100 kit today & here are the results - fc-7.5 ,cc - 0, tc - 7.5, ph - 7.5, t/a 140 , ch - 40, cya - 60, temp 80f. I initially shocked with 24 gallons bleach 6%. I added 1qt leslies algae control on the 5th day after running the pump 24/7 to clear the green water up. 2 days later used 2.5 pounds leslie chlor brite which i have 40 pounds of for the season. I am using 3 3" tabs leslies in my offline chlorinator at full. I need advice for the next step since algae spots r forming in various areas of the floor around the pool. thanks in advance. Btw pool is a fox lazy l approx 25k i believe,fox sand filter which i changed the sand last season, hayward 1hp pump.

Your CYA is already getting up to where shocking is going to be difficult. Stop using that chlor-brite and those pucks if they have CYA, which I think they do.
And it's time to shock, the right way. It's not a one-time blast, but a process.

Welcome to TFP! 
Leslie's Chlor-Brite is Dichlor where for every 10 ppm Free Chlorine (FC) it also increases Cyanuric Acid (CYA) by 9 ppm. The tablets are Trichlor where for every 10 ppm FC they also increase CYA by 6 ppm.
