Can I just say how absolutely amazing this thing is!!! Super easy to build and install! Make sure you use distilled water to fill it for clear water/no residue. 
The remote allows you to change to ample amounts of colors. You can fade colors slowly or even strobe light the colors. So many options. You can adjust the bubbles by turning knobs at bottom. Looks sooo good at the end of my hallway and a definite statement piece in my house. Everyone loves this when they see it!
