Hi,
I will have my 75g tank mid September so I need now to choose all the material.
In freshwater, I remembered we needed to respect a ration W/g but I didn’t find anything for saltwater.
What models do you advise me? Redsea 90/115, Maxspect, Popbloom?
I need something to put with arm on the tank.
I saw some Maxspect Ethereal 130W but I read somewhere they stop producing them?
To answer this question accurately, you need to provide the footprint of the tank (LxW) and also the depth of the tank.
When considering lighting for a tank, there are two things that are important; power and spread. it isn't enough to light the tank, but to light it with proper power at the bottom of the tank.
