So i was planning on getting a red sea reefer 250 untill i came across this at half the price the only thing is it has no sump so my question is do i really need a sump for a tank i plan on keeping a reef tank with a Moray eel 1 or 2 fish coral live/dry rock would this tank be adequate https://www.fishpetsreptiles.co.uk/...EthO7bVzMCDbBcIIL4dfDgcU7Mt2dr8EaAoj3EALw_wcB
