Okay...So Im wanting to do another seahorse tank but want to make it simple. Im wanting to keep 4 H. barbouri from seahorsesource. Wanting to do some more colorful fake plants and some tonga branching rock. Along with some sand. Was thinking about doing a over rated HoB filter that I would just make sure to keep it clean. Question being any good HoB filter that are recommended? Wasnt going to run a skimmer just going to keep up on weekly water changes. This sound good? Thanks
