Which Finnex fixture would be a better option for a 10g without CO2 - 20" Fugeray or 18" Ray II? I am new to this - and I want to plan on not doing CO2 on this tank (pressurized or DIY). Carbon dosing (Excel, otherwise), however, is definitely an option.
^Definitely. Since it sounds like the FugeRay itself might be more than enough light, and it is a little cheaper - I am more than happy with that. I was worried that it wasn't going to be enough.
I was just asking about the plant cover - because I hanging the light where I want to use it will be difficult, and I was going to try to go lidless on my rimless tank. But, I might need to modify that.
Even with floaters, you may have to dampen the light of the FugeRay a bit if you aren't running pressurized CO2.
If you want to go rimless, there are several things you can do to cut down your light levels. From window screen to theatrical filters. All can be easily attached to the fixture and can be easily removed without causing damage.
