Ok, so among my other builds that are in line I would like to have a minimum of a 120g FOWLR tank. This may seem like a no-brainer, but I am trying to figure out if I should even add substrate? The majority of fish that I would want to put in this tank will eat snails, crabs, shrimp, etc. so I won't have many options for cleaning up the detritus (that I can think of). I am thinking I could use CUC's and sand sifting stars, but that is about as far as my list goes off hand. Will the live rock alone be enough to seed the tank? Should I put just a very thin layer of sand? Should I just use a sand bed in a refugium? I feel like I have kinda "stumped" myself. Input PLEASE!

Well if you only go with the very little sand you may want to think twice about the sand sifting starfish, even though hermits are (lunch) for some of what your tank mates would like you can get a pretty good size clean up crew of hermits and if they do get ate well atleast your fish are happy because thats the most important part anyways right! ? Also there are urchents or some nass snails would be good for cleaning your sand substrate if you dont have much sand in there.

Myself, I gotta have some substrate. It just makes it look like the real ocean. You can always just use the old fashioned syphon hose to suck up the detrius... Just the live rock will cycle the tank... With a fowler, I think a big advantage is having the urchins. They clean so much algae. It's such a big help. I'd have a couple of them. Your tank will be dirty in no time feeding predator fish.

4" sandbed in fowlr for sure. more bacteria and more room for anaerobic bacteria.

I personally like sand...so that's what I have in my 225g FOWLR. However, many go with bare-bottom's for FO tanks. Many even go with no live rock (at least in the display). If you see many maintenance account setups or shows like "Tanked"....those that use fake coral inserts, have large bio-ball setups for bacteria. I ran into the same problem with my FOWLR and unfortunately have had to hold off on some of my favorite fish, like the Aussie Harlequin Tusk...because of the CUC. Urchins are definitely a great option if you have a glass tank. I love them for algae removal, but can't have them in my acrylic displays. Best of luck which ever way you go.
