Sand vs no sand?

[Leach29]

Thank you everyone for your replies.

Great to hear everyone's views, and thoughts.

Maintenance is going to be an issue for me, I was hoping to keep it as simple as possible. I am having it in wall with a fish room and my space is limited being able to syphon some spots due to framing ect. I will take pics and show everyone when I get my build thread going. It concerns me that I will have many dead spots.

If I have run refugium that would help with the water quality ?
