Any suggestions on a website i can find a good deal on glass tops and light setup for my 125 (72x18)...and im a lil confused with the tank and all being im new to this but theres 3 holes in the top of the tank where im guessin tops go and what do i look for exactly to get the correct setup for me, i could always go back to my lfs which said they could get me the lights and glass tops for $117, im just tryin to learn more and understand this...haha, thanks
