**Updated** Vase Nano Tank

Previously, I posted a video of nano tank I made for a few ghost shrimp with an under gravel filter with a PVC elbow sticking out for bubbles.

Today, I updated the tank by removing the extra pipe so the bubbles come straight out of the substrate. The under ground filter is still under the substrate, but it now has a sleeker, lower profile design.

Let me know which you like more in the comments.
