What I've done in the past is find a used light strip on craigslist and just used two. Hopefully something like that will work for you on this odd shaped tank.I am trying to do this project however i ran in to some problems. My 72 gallon bow front tank has only one hood about 28 inch in length. The plan was to put in four 26w 6500 bulbs inside the hood.
The problem I ran in to is that the bulbs are just to big. Any of the bulbs after 15w become to wide to fit in the hood with out touching plastic. I want to try growing real plants in the tank but with only four 15w bulbs in a 72g tank i believe that light would not be adequate. I could build a new hood for the back area of the tank however it would be complicated and very time consuming. Plus running a table saw and everything in my apartment is a pain. Anyone have any ideas?
You can try higher wattage, or use two light strips. On my 75g, I went out and bought those cheap walmart strip lights and retrofitted those. Works great.I did this on a 48" long fixture and put daylight 14 watts bulbs for my 100 gal and still looks dark. I may need to change the bulbs to higher wattage. I may get some at the website mentioned on the beginning of this threat.
