I am trying to decide between a 1 year old Elos Mini 20g tank and stand only (no sump, skimmer & return pump) or a new 50g SC Aquarium plug & play system (tank,stand, sump, return pump & skimmer). The Elos provides the aesthetics value that I'm looking for in a nano reef and may be easier for wife approval, however the SC aquarium gives more volume and less additional pieces to purchase. What do you see as the pluses/minuses of each, if pricing is equal?
