Hi,

will 36W T5 white light be sufficient for a 90L tank with valisneria and eleocharis parvula or will I need 36W x 2 ? Also I will use pressurized CO2 and EI method.

Thanks.

So its a 20gal TALL..

2 T5No on top of the tank will give you Med lighting.
1 T5Ho on top of the tank will give you Med lighting.

2 T5No 4" above the tank will give you Med lighting.
1 T5Ho 4" above the tank will give you Med lighting.
2 T5Ho 4" above the tank will give you High Ligh.

1 T5Ho 12" above the tank will give you Low lighting.
2 T5Ho 12" above the tank will give you Low lighting.
3 T5Ho 12" above the tank will give you Med Ligh.

Hope this helps

I think the best way to is 72 watts devided by 90L it will give 0.8 watts per littre. As I see from the 2010 AGA Aquascaping Contest most aquariums have lights raning from 0.6-1.2 watts per littre.

My tank is 58cm in height so at 72 watts I dont think the 0.8 watts per littre is very accurate but at least its close to what most aquascapers use.

Agree or disagree?
