You did a really nice job with your DIY!!!
Now my 2 cents about wave boxes......lol I understand why some hobbiest like wave boxes when they first set them up....but TO ME running a wave box all day and night is no different than sticking a 800lb bear in a 10' x 10' cage. If you don't think so stand in front of your tank and do the same back and fourth movement with your head and see how you like it
If you use a wave box put it on a timer so you have different flows through out the day in lieu of 24/7 Night at the Roxbury movement
OK drugs are wearing off time to sleep.............
