400 miles! thats crazy! As for being a nice beach, it may look nice but the water is teeming with stingrays, sharks and jellyfish.I've just been through all 16 pages. You, sir, are the DIY king! I was particularly impressed with the realism of the fake rock wall on this newer version of the tank.
BTW, that is one beautiful beach! Coming from a landlocked state 400 miles from the closest ocean, I am green with envy! Good luck with the new crabs!
