Nice man, you have to love that shimmer effect from Kessil! You’ll have to show us some up to date pictures of how the tanks look now.
So basically I have a small pump in each tank, but because of their elevation difference and slight tube length difference, water flows out of my display tank slightly faster than it flows in. I start by pumping water into my display until it's as high as I feel comfortable with, then I plug in the other pump so they run at the same time. I sit near the tank and let it keep going until I hear the return flow start to "spray" on the surface if the water. This is also my excuse to oxygen scrub the corals each day. I normally do all of this after feeding them. I love working on my tank and staring at it for half the day so I enjoy being able to interact with it daily. I only have to test one tank after exchanging the water for a bit
