Hi all - great board!! I have been reading & researching for months on this board, so much to learn! Anyhow, I am a long-time marine life lover and am researching equiment for my 1st SW tank - I still have much to learn, so I won't be making any quick decisions that will cost me or any fish pain. My current dilemma is deciding on a filter - I will be starting out with a 55g FOWLR tank with an undrilled glass tank. What would be the best filter for an undrilled tank? From what I've researched here & on the web - undergravel -out, canister - not great for SW & causes probs w/protein skimmer? Wet/dry/trickle - somewhat pointless as LR provides sufficient biological filtration - less, no need for bio balls or other such media... I haven't seen too much info on the mechanical filters though... For this type of setup - any recommendations? Also would like to see if anyone has any pics of their hang-on tank setups- just how cluttered does it end up looking? Thanks!!!
