Working on setting up my CL find $60 300gal rubbermaid tank outside. I am researching my filtration options and was wondering what everyone preferred as far as waterfalls or fountains go. I am more than likely going to go with a Laguna 900 because of the flow rate and it only using 65 watts. So with the waterfally basically the pump would send water into the waterfall box that will be filled with scrubbies or lava rock to act as the bio filter. With the fountain I will probably just stick it in a milk crate filled with scrubbies for the filtration. The waterfall will requre alot more work but in my head it looks much nicer and will be easier to maintain rather than having to drag the crate out to clean it I can just move a piece of flagstone or whatever is covering it and clean it out. Whats everyones opinion on the matter? The pond will be getting a lot of sun so should I go ahead and install a UV filter as well or just deal with that problem when it comes along?
