How many G5s?

[adamf83]

I’ve settled on the EcoTech Radion G5 lights as an upgrade to my tank, but I’m not sure on how many I’d need.

My tank dimensions are:

Width: 80cm
Height: 50cm
Depth:35cm

It’s a Fluval Roma 125 - https://charterhouse-aquatics.com/s.../fluval-roma-led-125-aquarium-and-cabinet-oak

A single XR30w or multiple XR15w?

Any advice appreciated.

You could get away with a single xr15 depending on what you are planning on growing. Any idea as to what coral you are aiming for?

Not 100% decided on sps or lps yet... I have a few soft coral which are doing ok, but I suspect could be doing better with better lighting.

If SPS with heavy acropora, then double up any manufacturers recommendation. If mixed, then what they recommend is mostly fine until stuff gets large, then shadowing is a huge issue and most add in some T5s in a hybrid type of deal.
