Hello All. I am just about to enter my first full season as a pool owner. I acquired one of the salt water test kits as recommended on this forum. I removed the cover from my pool yesterday and got the filter running and did a thorough vacuuming of the pool. I had tested TA and it was in the 20 range added baking soda last night and this morning it tested at 70-80 and PH tested between 7.2-7.5. The CYA and FC were testing at 0. Currently, I’m using the sock method to add stabilizer to increase the CYA to be > 30 for the purpose of starting the SLAM process. However, since the water is very clear is SLAM necessary? If not, what should my next steps be?

Ancillary question. My pool came with a nature 2 cartridge installed. My research seems to show that these are not recommended by people on this forum because it introduces unwanted metals into the pool that can cause other issues. Should I remove the cartridge or is it enough to just not change it with a new one?

Add at least 5 PPM of liquid chlorine and do the Overnight Chlorine Loss Test. If you pass then no SLAM is necessary.

If you can remove the cartridge then do it.
