i have just finished the SLAM and ready to balance the water. I had trouble with determining the CYA with the SLAM and erred on the higher value. I'm retesting and get values between 50-80 and it's driving me mad. If I had to pick a number I would say 60 or 70. My FC is down to 6 so I feel it's close to algae problems and need to move forward.

CYA. - 60? - 60/70. -
salt no test but assume approx 4000 will test tomorrow at pool shop.
Ihave been adding a kg of buffer each day to increase TA slowly.
Im brushing every day and filter on high setting for 8 hrs.Still having trouble finding the right ORP for SWG but may need to manually turn it on to generate FC as it hasn't kicked in the last 2 days hence the drop in FC as we have had sunny days.
I am reluctant to add any CYA to get to 70 as recommended for SWG as I want to be first certain of the CYA level I have now.
CYA level ???? So target FC???
Any advise from the experts?
Should I just bump up the FC say to 9-10 either with SWG or liq ch before I get into algae problem.
i will check tomorrow morning if FC has dropped and CC raised over night.
