Fish Aficionado
I agree, the 2800k bulb I have is pretty red, and I am liking to get another tube (2 total) of like a 11,000k bulb to even it out. So will have my 2800K bulb, and then around a 11,000K bulb. But like aaronnorth said, go for a K rating of around 6,000-11,000K.so if you don't go above 2wpg then you don't have to add anything to help them grow? or?
going above 2wpg needs CO2, and heavy fertilisation.
medium lighting (ie 1.5wpg) doesnt need CO2, but it will need fertilisation
low lighting (1WPG) wont need CO2, and possibly no fertilisers. Maybe an addition of a fert once a week will do as generally the fish will provide everything.
Go for a kelvin between 6000-11 000k
I am saying a bit higher than FHM simply because i feel that 2800k is to red/ pink unless you have 2 tubes, so you can mix it with a white tube (8000k) to balance it out.
Also, the daimeter ('T' rating) can knock the wpg guideline way off the charts. 1wpg of T5 will be similar to having 2wpg of T8. Due to T5 giving more watts per square inch. T5's also penetrate deeper into the water column.
Well written response aaronnorth!

. though I do have one question. Why is the tank so empty? as in, the water level? It seems awful low?
