Nano bare bottom reef tank (9 gallon)

[Vanlife-reefer]

I recently had my tank crash.

I decided to start again and this time it’s 9 gallon (35 liters).

I have 2kg (4.5 pounds) of rock and I’m going rather lightly with life stock.

I decided to go bare bottom.
What problems can I come across later?
I don’t want sand as I feel the rock itself looks way cooler and I never had bare bottom.

Please tell me your thoughts.


Btw, this tank is a permanent fixture in the RV that I live in. Yes, you read it right :)

Definitely go for it. You can always add a couple cups of sand. I love the look but it never worked out for me.
