This is a video of my FOWLRFC Tank (fish only with live rock and faux coral):
I was able to use various ways to keep nitrate and phosphate down with refugium, sugar addition, reactor and high flow. As a result algae on artificial coral are kept at very low level.
The tank never had water change since setup almost two years ago, and the artificial coral were never removed for cleaning.
For those of you who don't have the resources to do a real reef, yet want to have the closest reef tank experience, there is hope.
And many efforts were made to keep the tank super quiet if you noticed.
