It doesn't list B vitamins in the ingredients, so I guess not.
It is in packets, and I just read that each package is for 20G's
Any dosing recommendations fo that???
Should I take out the 2 snails I put in?
OHHH Do I take the carbon out too? Or leave it in **EDIT...the directions say to leave normal filtration
EDIT#2...I just read the pamphlet and it says it is non-toxic to invertebrates
LOL....I'll keep reading...
EDIT#3 LOL....Apparently saltwater Maracyn DOES contain B vitamins
gotta read the fine print
