Does anyone have any recommendations for a powerhead for a 50g? The tank is going to consist of Gorgonians, Dendros, Sponges, Sun Corals, an Acan and a Ricordia Mushroom. I've looked at the Nero 5s, but they have a reputation of being fish traps. I saw the Nero 3 is coming out, supposedly with a better fish guard, but I'm not sure if 2,00gph is enough for a 50. Any recommendations are welcomed!
