Hello guys , I just got my new kit tft100 and before that i was fighting a green swamp where I live in Puerto Rico, Caribbean. I gathered all the values so here they are for a 17000 gallons in ground plaster pool :
I put everything inside the cylinder of CYA reading and could see the black dot completely when filled up to the top, does that mean my reading of CYA is at 0??
I want to shock the pool to get the CC to less than 0.5 or 0 if I can but with the CYA at 0 I read in the pool calculator that if it is at 0 then i cannot go above 5ppm of FC which I already am.
Here is a picture attached of how my pool looks like right now. On the left side there is still algae color = grey that im gonna finish brushing up today and more vacuuming as it goes.

Question is what should I do now?? Can i bring my pool to shock levels of 10ppm FC to shock it and tomorrow start adding CYA/Stabilizer to 20ppm or go a little higher on the CYA/Stabilizer since I live in the tropics??
