the one in the first link is the more common of the two. All land crabs are brackish. They all live by the sea. My pic in particular is an asian land crab. there are thyland crabs and chris just had some HUGE red land crabs. May still be there. Very heardy scavengers. But not all that fish friendly.
If you built a pond, as a sump, you could cordon off one area with a gate of sorts and have a return pump be installed there back to the main tank. Have the main tank flow into the pond as the overflow. Easy. Just like every other system here, but a pont as a sump tank......

I will just give my warning that your system will flood, bulbs will burn out, and things will take continuous maintenance... get over it.

As long as the pond/refugium is higher then the sump you should be able to have it stay at a constant level. Just like the huge multi level systems at bird world and the aquarium. Water could flow from main tank - pond/refugium - sump this would require only one pump. You could also have it setup with the main tank to sump, and pond/refugium to sump but this would require two pumps. You would have to that the pond/refugium be higher then the sump in order to have the pond stay full.
You could also do something like Skyetone said and just use the pond as the sump. I know that my sump has a refugium in it that always stays full. Its only my pump side of the sump that water lowers in. I'm sure its that same way with 90% of the peoples sumps on this board.

I have a 50 gallon rubbermaid container (50"x30"x12"tall) that im using for a mangrove refugium. I think I'll just use that for some crabs. I can still have a sloped bank and a little island with mangrove "palm trees". I think that will have to do for now.

Make the sump your pond! (you wont need a skimmer with heavy algea growth --- if that growth is maintained and pieces that go sexual are removed)
currently my 20 gal fuge is the sole filter of my 125 (the skimmer has been curing LR for several weeks)
and my nitrates are still zero
I think a saltwater pond could be made really cool using regular pvc pond liner and agrocrete rocks for the sides with some additional sead rock.... think of the mangroves you could grow!!!
This pond would serve as your sump, your fuge, your frag growout area ect ect.

What about instead of a pond, you had a tide pool? There is a great design in my new book.....I'm thinking adding it to my seahorse tank.

I really like this idea Suzy. So what characteristics would make it a tide pool?

Oooh Oooh Oooh, if you want a tide pool talk to me. I once had to design an alternating tide pool system for a public aquarium. Basically take two tanks (like lets say two 55 gals) and have them alternate every 7 hours of one at high tide and one at low tide. This can be done with tanks side by side, or one above another. I think side by side is easier.
If you buy the equipment, I'll come over and make it for/with you.

You bet. March 10th is my next free out of the lab day. So after that day we should be good. I'll give you some plans and you can decide if you think it is worth doing.

Dan, thats a good point on the skimmer. The whole 180 will be planted with sea grasses and macroalgaes, plus i'll have the 50 gallon mangrove tank. I bet i'll be adding nutrients. Im going to use a DSB of utah sand so i'll probably need to use some fertilizer spikes or something to get it going. Im already preparing for the algae bloom that will follow

Instead of fertilizer (scary) how about a hefty fish load???
Ive found that my macro stops growing or grows very slowly when I am stingy with the feeding and fish load.
As a macro connoisseur this is somewhat unacceptable. I think macro algae is underrated in its nutrient removing capability's, and i think most refugiums are not properly lit or designed to accommodate aggressive growth.
I just removed 2-3 pounds of macro today (its at fish for you now) and I attribute this to my skimmer being on another tank. I was able to buy some nice stuff from FISH FOR YOU with the credit. My normal harvest would be less then half of this.
One point I wanted you to realize with your algae intensive setup is: Algae must be harvested regularly ( which can mean profits) and Algae must be fed (higher then normal bio-load)
IMO the nutrient removal of macro algae is simply amazing... when well lit and free from predation....

Hey Dan, if you don't mind me asking, how much store credit did you get for your macros.I have tons of chaetos I have to harvest, tryed to give them away free but no body wants them so I can as well just get some thing out of this fast growing thing.

I just had another idea....
settling .... You dug out a hole. filled it with concrete, then plan to put between 800-1000lbs on top of it. Did you compact the dirt at all before the concrete? Look at most wooden fences. Not square... No big deal, but with a fish tank that could get ugly....

Chris knows what he's doing and im not expecting any problems. The stand is solidly built and could probably hold twice the weight it needs to (1500-2000lbs)
