I like this affect.
Great idea for FW
but will be ineffective for Doan
set up. Bubbles do not provide enough surface movement to properly exchange CO2

Keep in mind that most manufacturers rate their filters while empty. Once media is added and return head pressure is calculated, the flow will be reduced by as much as a third. In a SW
tank, canisters can be used effectively but the flow is inadequate and must be supplimented with PH
That said I comepletely agree on the Maxi-jets
