Got a 50 gallon aquarium, put 5 plants in and after 3 days with Quickstart added 6 Australian Rainbows. Got the Marineland C-220 Cannister filter, couple of heaters, and a plant light bulb along with the regular bulb that came in one of the 24" hoods. All is going well. Just keep getting bubbles coming out of the filter every 3-5 minutes, guess I will try some o-ring lube.
