Ok so someone got out of the hobby and gave me a 120 gallon tank, stand, and wet/dry filter. My question is: should I keep the filter he gave me or buy a sump? It is an Eshopps 300 Trickle filter with dual overflow. I'm planning on transferring all of my current coral, fish, etc. to this so I'm planning on a full reef for the 120. Would this filter be ok? Here's a pic of the filter I have now!
