With KZ lets use the 50 ml bottle. at 7 drops per day= .7ml the KZ bottle would last you 71 days. at $49.99/71 days = $.70 day. Using the 100ml bottle that would last 142 days at 79.99= $.56 a day. Would definitely like to see your assumptions on how a 50ml bottle is the same as a 1000ml bottle of Acropower.

I think your math is a bit off in the sense that acropower is only dosed once per week (or you can spread that single dose throughout the week if you choose, but the total is still the same ml)
In that case, at 35 ml per week (should really only be 30 and 6 drops for a 150 gallon tank, but we'll keep it consistent with your 7 drops), the 32 oz bottle of acropower would last 189 days. At about $32 a bottle, that would be what, $0.17 per day?
