tide pool tank

I have a 5 gallon set up and have done saltwater aquariums before I had a 75 gallon seahorse tank. I’m wanting to do a 5 gallon saltwater tank with things. I just get off the Oregon coast so sand ocean water and then what I’m able to find in a tide pool. I’m curious if anyone has an idea of what...

Hey all, has anyone seen a tank in someones home or does anyone run a tide pool tank? Building a 48"x36"x13" tide pool frag tank. I can go into the logistics of how I'm gonna do it later but I just wanted to see how anyone else have done theres. And as always pics are always the best!
