WOW! Can we take it down to defcon 2 in this thread guys?
I know Matt and he is never 'snarky' on purpose. He is very knowledgeable and just trying to help.
Let's keep this simple. Go to walmart and you can get a 10 watt flouresent bulb in the aquarium section for $5. They are super slinder and fit even my 2.5 gallon tank.
Moss balls, IMO, are totally useless and a waste of money. With fast growing viney type plants, like hornwart, you not only get good algae control, but you can make frequent cuttings to stick in the gravel other places and make new plants. Cheap and effective.
