Self Cleaning Betta Aquarium - Simply pour fresh water in, and dirty water is expelled through a tube and out of the tank while your fish swims happily within. There are no filters, batteries, or cords. by cecile
Make a 3D Aquarium Background
I made this background for my 120 gallon aquarium. It was actually pretty easy to make but it was very time consuming and messy. I'd definitely do it again though! It was a lot cheaper than buying a custom made background and you can make it exactly how you want it. This instructable will walk you through how to make one of these backgrounds. You can adapt this to any size tank. The materials I used are fish safe. ***Note: This is only for FRESHWATER aquarium use!!!
