You can go sump also but I highly recommend to drill the tank if possible cause a hob
over flow can lose siphon an Drain the the tank. I'm building a sump for my 55g upgrade instead of going back to the aquaclear that is currently on my 10g.
Sumps have lots of benefits as hiding equipment, fully customizable, more water volume, algae can grow in it if you have a fuge, you can fit a bigger skimmer, you can fit reactors in it, you can build a diy algae turf scrubber, really the possibilities are endless.
Now for the wet dry filter, there alright but the bio balls commonly found in them trap deturis an other objects that decompose. I find that a compartment filled with rubble rock, a good skimmer, filter socks, and a fuge gives everything needed for a saltwater tank
