Okay, I confess, math is not my thing. 20 gal hex minus maybe 1 0r 2 gal sand and decoration. Probably can stick to just 20 gal?Yes; dose @ 60mg/gal.
My package (from ebay with good feedback) says 40 mg is equal to 1/8 tea
I need 1200 mg (20*60)
That would be 30 1/8 tsp (1200/40) or
15 1/4 tsp or
7.5 1/2 tsp or
3.25 tsp
Do I have this correct? Edit: Ugh, I have just a hair under 3 tsp. Will this work?
