If you are creative you can get a 4 foot light hood for under $130 with 2 t5 bulbs that plants love.
They had the light fitting on special for about $60 the other week and we got some paint, timber and wood shelving brackets so we now have a light hood that doubles as a shelf on top of the tank for your food and stuff.
Also their irrigation section has everything you need to make any filter pipe you will ever want. The small irrigation hose is the same size as air tubing but black so it hides better in the tank
