You can swim in your pool safely if:

1) The FC is above the minimum per the FC/CYA Chart and below the published SLAM level.
2) The water is clear; and
3) You can see the bottom of the deep end.

Many people here with good CYA levels run their pools in the 5-10 FC range all the time - within that range it's well below SLAM therefore safe and sanitary.

People often say they can 'see heads or tails on a coin flipped into the water'. Your pool is obviously not super deep, but that's not a terrible way to check. Fun game for any kids around to dive to fetch it too!
