I have two large aquariums (125 & 150 gallons) I am going to convert into vivs. Neither has a lid or top currently. I would like help/ ideas / pictures on your lids and viv tops. How do you construct them. Are they mostly screen, or screen / glass combos or wood ? How high up are the lights from the top of the tanks ? Etc Etc... I assume I could build a lid/ top frame out of wood and cover the open area with screen. Im not sure how much should be open air/ screen versus sealed/ solid covered. For vivs this big Im assuming 4' lights would be the best bet. Any help (photos are great) on lid/ tank top construction is appreciated.
