I think of jumping from the 55 gallon I have now to a 300 gallon Rubbermaid container someone said in another thread they sold at Tractor Supply Co., upgrading sometime by the end of the year. I lost the link though, but when I checked the price a month ago they went for about $190 at my local store. I'm thinking of putting it in the porch or in the backyard. More sun shines in the backyard though, so I'm pretty much opting for the porch.
What would be a good filter for a habitat this size? Thanks for anything.
