I am also not an expert on heaters, but I can only afford one per tank (times 6, soon to be nine tanks, and I'm broke
) A lot of people will tell you 5 wpg
is good (or is that 5 wpg
of light for planted tanks?). Anyway, my theory is that the larger the tank is, the less wpg
you need, because the tank is not loosing heat to the air. A smaller tank will need more wpg
because it is loosing heat faster than a larger tank due to more surface area per volume of water.
