i wouldnt get get a digital and buy the underwater housing. that way you could have good pics and still use the camera else where. the cameras in the sea and sea are not that great and for around the same price you can get a nice digital.jmho
are you going to have a overflow or ho filter? if over flow get a wet/dry and skimmer. if ho get skimmer i like the The Berlin HO around $175 or CPR Bak Pak Dual Pak $200 and 2 Emperor Power filter 400 W/BIO-Wheels about $50
beginners need larger tanks because they are easier. IMHO small tanks are hard and are for more advanced(i.e people with some experience). so at least get a 29 that way it is a little easier and it only costs like $20-30 more.
i am also wondering this too. im setting up a 300g this summer and dont know what pump to get. dose anyone know? triggerfish im thinking of getting a ASM G-4 Protein Skimmer.
