Slowly getting together a new setup. Been a few years since I've had the room for something. It's small but hoping for the best. So far I've got: 30 gallon aquarium (drilled) 28 gallon sump (commercial trash can) 1 bus tub for a possible RSWC Have fitted the parts together, currently have the tank stocked with tropical community fish. Changing over to a pair of gold fish possible. Have read the plants prefer the cooler water temps. Aquarium drains into tub, then into the trash can where a return pump sends the water back up to the aquarium. Ideally would like to run a few staggered fem clones. Possibly do a small aero garden style bonsai moms in a small veg space. Cabinet is about 2' sq. Would the mars hydro 300 be a total wast of money? Jade plant seems to like it so far. Hoping to get this winter project kick started soon.
