DIY canister filter for nano
I'd like to get your input on an idea I've had. I'd like to add some extra bio filtration in my 12g nano but don't have any idea how I could manage to build a sump with a tank like that that's already setup and almost a year old.
I tried to buy a canister filter off ebay but that didn't work out too well. I was going to fill it with live rock and I thought that would also give the water a little more movment as well as provide a little extra filtration.
So here's my horrible little drawing
