I dose one every night. Hence the 3 jug rotation. But i have a 55gal with 20gal sump. They are one gallon jugs, and i put 2 heathly spoons of mrs wages lime and fill it up with RO/DI, let site overnight, then drip. Works great for me. How often you dose would depend on your tanks needs.
Dude, im talkin all gas, shiftin gears, not a break light in site!!!!!! Ya really got to watch out for the crazy ones. Caught her in a lie, I stopped in the middle of the road, got out, and left. Really cant stand liers
