I inherited a tank and would like to change the lights

Well after that the lobster proby is gonna do a better job on clean up the battle field at the end =p. This is just for laugh and back to the topic. I would suggest trade in a pair of ur clown and the lobster in this case to ur LFS for in-store credit for future.

As for lighting, you can even consider the zetlight nano, few of the ppl I kno did that and mod 2 of those into their canopy and works fine. They are also the sponsor for 3reef. I think for a small tank like yours,don't really need to spent a lot.
