Quick background bought a home with a saltwater pool. Don't trust the pool service companies and want to take care of maintenance myself. Actually they included a free month of pool service and my numbers don't match the tag they leave on the door. Something tells me they skip out to save some money. Got my TF100 kit here are the results.
pH: purple as can be 8.0+
CYA=??? Did this test twice, could always see the black dot at the bottom of the view tube. Not exactly sure what I am supposed to see, looks like I was just adding water. Some help here?
Overall pool appearance is great, water is clear. Minor hardwater type scaling on tiles and rockwork. Cleaned some of it off with a pool stone...not sure if thats the best way.
All advice welcome!!
