i dont have a favorite but i have one that i would never recommend... The Simple Guide To Marine Aquariums, probably great information, back in 1990.... It just that its the old fashion way of doing things (undergravel, bio-balls, crushed coral, PC lighting is second best, 3-5 wpg for corals, didnt say much about live rock, just said "aquascaping" and they recomended that you use foam blocks as the aquascape to make it look like rock, just an overall oldfashion book).
