lighting for a 92 bowfront corner

i currently have a 36 inch 25watt bulb but i dont know the exact brand bc it was one i bought with the tank...the light is good but i find it doesnt reach the the back of the tank like i want it..whats the best brand and size to go with? sooner or later i might go with a two buld ballast.

Try using an aquq glo with a power glo bulbs and you will find the right light you are serching for. I have them on all my tanks and it looks amazing. Nice and bright with very little dark areas in the tank. Only dark spots in my tank is where I have the rockwork. Makes the colors of your fish come alive!!!!! Plants thrive and become really big and healthy. Try this out and find out for yourself.
