FC going under recommended level

[Tfpoolfromthestart]

Quick question,
My FC drops below the minimum before I top it up in the evening. Is this something to be concerned about?

This can give algae a chance to get a foot in. You should target a higher FC when adding chlorine to ensure that you stay above min all the time.

Minimum +
Recent daily loss + (a seasonal moving target)
1 to 2 ppm wiggle room
-------------------------‐----------------
= trouble free pool

Min is lava. Avoid it, or being near it at all costs.

Yes

Dose to high target or even a scootch higher if need be & replenish before broaching minimum

Playing kissy face with minimum is a recipe for algae or worse
There’s no downside to having a little extra chlorine but there’s many downsides to having too little.
