Here we go

look good man. i would put one baffle int he MG to keep the water leve constant in there. other wise the evaporation from the tank and what not will take its tool on the MG and not just on the pump compartment.

other wise i would say why not! the wet dry part really won't be necessary just put the LR ontop of the miracle mud. you can have more inthere that way. better filtration. Good shit!!

unless the mangroves are on display i would go with some kind of macroalgae since magroves dont pull too much out of the water.

Really?I thought it depended on the species of mangrove.Like the "red" ones.
