Lighting questions for a tall tank
I am debating on if I should go 18" or 24" tall on my next tank....(24L or 30Lx12W)
It will be low tech w/o co2 and low lights...maybe dose excel once here and there but try to keep it as simple as possible...currently I have a low tech shrimp tank and most likey I will use the plants available in my low tech tank or just get some more low light plants....
my question is that if I go with 24"...i will need to use a high wattage bulb for the light to reach down to the bottom where I will have microswords for foreground....but that means the upper tank will have higher wattage and I am afraid that will cause algae problem...what should I do? or just go with 18"? thank you
