I have a 55 gal with a placo, red devil, JD, convict, and a texas. Someone just gave me a 100 gallon. Outside of tanks reads at 73" long, 19" wide, and 19 1/2 tall. I was planning on using 2 of my HOB filters with a canister filter on the 100. But the HOB filters from the 55 will not fit. The lip on the 100 gal is 1 1/4. What are the suggestions on filtration? Also, I have no lids at all. Can I just buy the crossbars and use 3 24" hoods and lights? I need some help. Any suggestions please. Thanks in advance.
