i've had this idea for quite a while, i want a system that appears to have no filtration or external plumbing but standing alone on my desk. this will eventually manifest itself in a higher quality build but in the meantime i have more ideas than funds. what i'm doing is building a "zoatope" that has all the filtration in a small sump hidden by my desk. the live stock will be three bumblebee snails currently living in the sump and possibly two sexy anemone shrimp in the future. the tank is a $10 Marina Betta tank. as you can see, there is a notch out of the back which will become the "overflow". i'm planning on siliconing a nylon hose to control the path of the water and reduce splashage (why does firefox tell me that's a typo, it's totally a word). i've also fabbed an acrylic splash box where the overflow water will collect and run down a drain. i just need to drill the hole for the bulkhead and finish the silicone. for lighting, i've got five strips of LEDs (2whites and 2blues and 1UV/purple) that i'm gluing to the underside of the lid the finish produce should look like this, with the drain and plumbing blocked/hidden by my computer monitors. the back of the tray just hangs over the edge of the desk and i'll run nylon tubing into the sump. right now all i've got to move the water is an Aqualifter but i'm betting i'll need something more substantial than that... it's still all in the planning phase. let me know what you think, offer any suggestions or let me know if you see any problems.
