Right now in our 40-gallon tank we have a 100-watt mercury vapor bulb (MVB) in a dome fixture as well as a ZooMed ReptiSun 10.0 UVB T5HO tube light (22” long). Can we make these work in a 75-gallon tank? If not will we need to get rid of these fixtures and get new or maybe just change out wattage? Would love to be able to reuse or add to what we have but understand if it just won’t work. Thanks in advance.
