I kinda have the same question as him. I planned on building a wet/dry system myself for under my tank. Would just a plain old sump be more beneficial? Havea protein skimmer, should be here so0n
Thanks
A sump gives you an easy way to increase the total water volume of your system, and also provides for an out the way place to run heaters, skimmers and the like. Since they generally have a very high turnover rate this make s for the ideal location for FW top offs and anything being dosed to the system.

The addition of a refugium and some marco algae creates a biological filter and offers a safe haven for raising other fauna.

A wet/dry will work, for a limited amount of time, they are good for removing ammonia and some other harmful stuff from the water, but it will fill with junk removed from the water quickly and the mdeia will become a huge source for nitrates that will pour back into your system. A sump/refuge is a better route to go.
