i just ordered a new 135 tank, stand, canopy and glass top (finally). i ordered it from the place in tennesse. the canopy and stand come unfinished but i dont think that will be to hard to do. i have been waiting forever to get the money for it ( yay for birthday present from fiance). now down to bussiness, i have never had a canopy on a tank. how much sealant is needed to do the canopy inside. is there a special kind or can you just use regular laquar?
