starting up after winter

[costo]

I guessed on the cya since it was between readings . I added borax and bleach to shock level this am after getting test results. Thought I would test again this pm. I had thought the algae was dead but I think I may have lost some ground while we were gone. It is starting to look better but is still havin some grEen discoloration after brushing. I am still recirculating without the filter.

Also I bought chlorine tablets to float in pool while we were gone. Ingredients say trichloro-s-triazinetrione 93.6% zinc sulfate monohydrate 3.5% other ingredients 2.9% available chlorine 84%. Are these ok to float in the pool?

Also, it only turns greenish in some spots right when I brush but most of the water is cloudy /milky blue

The tabs are ok except that your CYA is already high enough and those tabs add CYA. Go ahead and leave the ones in the floater that are already there, but then don't put anymore in. You can save the tabs to use for a short time if you go out of town again this summer or upon opening next year if you need to add some CYA.

Keep your pool at shock level. Also, keep an eye on the pH since those tabs are acidic and will drive the pH down. Go ahead and put it on circulate.

Its starting to look a lot better after I stir. In fact I think the little discoloration I get is due to dirt. It quickly turns back into a cloudy/blue. Tests this am. Fc: 14.5, cc: 0.5, ph: 7.0. I see what you mean on the tabs driving the ph down cause I have been adding borax to keep it up and it keeps coming back down. I added more borax dissolved in hot water and the pucks are almost gone so hopefully that will solve this issue would it be okay to put the filter in at this point to try to clean this up? I have vacuumed a few times and gotten quite a bit of algae out. I cannot vaccuum to waste as imy vacuum is hooked up to my pump.
