Just noticed it on Dr. F&S. Says it treats 40k gallons. Regular 2L Prime bottles say 20k gallons. The seachem site says it's more concentrate, do you believe it? Or is it just marketing since overdosing is ok with prime. The price (on Dr. F&S) is better than regular prime which makes me wonder. Thoughts? Opinions?
