No visible algae, but 0 FC

[Ryan-Cal]

I turned off my salt cell and forgot to turn it back on for a few days (turned off Sunday or Monday, and remembered to turn it on today, Friday). There’s no visible algae. Do you think I need (a) bring up to range w liquid chlorine ASAP, (b) do a shock at SLAM level, or (c) do a full SLAM. I don’t think I have algae yet.

Yes. Take the FC up to at least 5-7 ppm (assuming you have some CYA in the water) and do an Overnight Chlorine Loss Test.

Great. Thanks. Will do.

I have 50 CYA.
