I bought a rimless 90g (36"X24"X24") Miracles tank from a fellow reefer and i would like to put a canopy on it. I like the rimless look but i want to have less evaporation and to be able to put the fish i want in it(i already have lots of jumpers). If had ordered a custom tank, it would not have been rimless but this one was the dimensions i wanted and the price was right.
So if i make the canopy as light as possible, can it cause problems for my tank?
