Hi, first post for me. I've for a Clearseal 48x12x18 tank and just finished building a stand for it. I'm converting the tank from a few goldfish to a tropical set up with live plants (hence joining up here). Not sure how to go about lighting. Need to change what I have and unsure whether to get a new lid or go lidless and get something to clip to the sides of the tank. Hanging is not an option really. I'm also unsure if lidless is wise as I have mild asthma and humidity is bad and can act as a trigger for an attack so sence says not to, but as I say, it's only mild. Thought about a couple of sheets of perspex to lay flat on the top, but might go green quickly and be a pain to keep clean. Any thoughts welcome. Not an overnight project to convert but I'm getting there, still need another tank for the goldfish yet.
