How Many Mitras??

Hi,

Im new to Ghl products and I’m considering the Mitras LX 7206 for the Peninsula build I’m planning. Unfortunately there is not much in the way of reviews out there and Id like to get it right first time accounting for longevity.

The proposed tank build is - Length: 140cm, Width: 75cm, Height: 62cm
How many would it need for mixed reef?

I have considered:
a)2x LX7206 horizontal
b)3x LX7206 perpendicular
c)2x LX7206 perpendicular & 1x LX7204 I the centre

Thanks
