I have a corner tank and it is a big PITA to light. I am trying to think of other options maybe a smaller light towards the back and then the longer one up front. The sides is what is the difficult part to deal with I have thought about begging my son to make special legs for it but he deals mostly with metals and I know what salt does to metal. I am glad I set it up as a SW
instead of an African biotope. I had everything but the fish for the biotope and changed my mind. The light I was going to use for the planted tank has the wrong spectrum for a SW
tank so I tucked that away for another tank or if I change my mind on this one. Filtering is another big problem, and is water flow.
Right now a month into my corner tank I would have to say it is worth the hassle.
1 rule is go as big as possible more options and less problems. I started with an 8 gallon nano and have the corner tank which I think is either a 40 or 45 gallon. I love my nano but top offs and maintainance is twice what the bigger tank is.
