 Re: water flow ?
You dont' actually "need" to move water, it just helps circulate the water around the tank keeping detritus off leaves and ferts in contact with the plants. Believe it or not, some people use NO filtration at all. Some use filters for water movement only.
In a heavily planted tank, you might need to turn the tank over 8 times per hour, or even more. But in ligthly planted tanks, you might not need anything more than what you had. Don't spend the $$ on a filter until you see that you have dead spots (no movement or detritus accumulation) in your tank.
I have seen tiny HOB filters for the JBJ 3-gal pico-tope tanks. I'm not sure who makes them or where to get them though.
