I've been wanting to try dwarf puffers for a few years and finally decided to go for it. For the last five years I've been all saltwater but shut down my last aquarium almost a year ago in preparation for moving out of my parents house. I still haven't found a decent house yet and I'm starting to have fish withdrawals... I couldn't take it any more and decided I could set up a fluval edge shrimp tank, that would be easy enough to move. When I went to Petco to get one though, the $1 per gallon sale was on... and I figured a 20 gallon could be drained and carried out... and I could finally get a couple puffers...
Being in saltwater and having sumps on all my tanks spoiled me and now I can't bear cluttering up the tank with equipment which is why I'm installing a false back where the heater, filter media, and circulation pump will go. For the divider I'm trying this 1/4" thick HDPE sheet
which will be siliconed in place 4" from the back of the tank. I did a mock up with cardboard to see if my hands would fit back there and make sure I had the overflow height right.
When the sheet arrived I marked out where to cut it and used a jigsaw to cut from each side toward the center, then drilled holes in the middle to separate the two pieces.
Some filing and sanding cleaned up the edges and I glued it into the aquarium with silicone two days ago. It's outside now full of water to see if there's any leaks, better not be. For the circulation pump I'll be trying a maxi-jet 1200 shooting water back to the tank through a Hydor Flo deflector
. That's a neat little device that uses water power to rotate the output around for better water motion. I need to run to town and pick up a fitting to connect it with the maxi-jet and ball valve, then I can see where I need to drill the hole in the false wall. Hoping I can get that installed and fill the tank up tonight!
