I'm no SIP expert -- but I stayed at a Holiday Inn once!My SIPs had a definite funky smell after last run even with running EM in there. This time around I'm trying to decide at what strength that EM should be for my rez which if filled all the way was several gallons iirc - but I normally just refresh with 2 gallons at a time here & there when I remember to check with my dipstick. Last time I topped off with 2 gal I used a full cup of activated EM but wasn't sure really how strong that would be given the bottom feed/wicking nature and the goal being both plant health/benefits and knocking down any funky odors.

But seriously folks... I've had lots of experience with root rot and GFF always helps.

Use 1 tsp /gal as a preventative or 2 tsp if you've got problems.
It will help.
