so a regular HOB filter that uses inserts (basically a bio wheel with no wheel) is okay? Also i was thinking about it and I realized i might be able to build one cheaper than buying one (a tank i mean). So i came up with the following dimensions 16x16x30 which would give me about 40 gallons would this be more ideal (i had hight in mind).

Also i love on the jersey shore (basically 10 minutes tops away from the ocean) zipcode is 07755.

Another thing i saw (on this forum) a lot about making real rocks out of cement and sand or crushed coral but I'm really confused, could i make a structure out of PVC with places for the sea horses to hang off of and then cover it in this cement sand mixture and use that as part of my "needed live rock". sorry if that is a stupid question i was just thinking about how to have the needed rock with out busting my wallet.
