MTS - I have more than I need. My plans have changed, I'm building an Aquaponic system vs. planting more tanks. The clay is in, I'll include the correct amy. of Potash for your tank foot print. I do not have Dolomite.
This is with out question the best batch I've made so far. Over a month of aging, at least 7 cycles.
A large Flat Rate box will hold 720 cu. in
And a Med will hold 440Cu In.
The math on your tank needs is L x D x 2"
>>>So a 20L would need 720 Cu. In. or 1 lg. box
a 55 would need 1152 Cu, In. or a lg & md box.
Larger are $30
Med are $18
I might have 4 Lg. size boxes total in my storage drum???
