ill be the one to tell you, no you dont. as long as you over filter the water like a refugium or a strong hob
filter, your good. im running a 36g bow front with just a hob
rated for 75g and it does WORK. i just keep up with weekly water changes and filter/media swaps as long as you follow a strict routine your golden.

true, im maybe contemplating a nano skimmer for my tank but so far everything is happy and healthy. i plan on maybe 5-6 fish tops and corals too so far its going very well.
