Mitch - it is 84" long by 36" wide by 30" tall. Plus the external overflow that adds another 6" to the length, but that is invisible except from the fishroom side.
I did a 55g water change today and am mixing up another 55g for tomorrow. I'll see about getting the nitrate down although the damage is already done unfortunately. Yes, I'm doing a 4" sand bed again. That is why there is a pallet of sand in my garage right now, awaiting the new tank. If you run a 1" sandbed, you can siphon it clean as often as you wish. Steve Weast only had one bag of sand in his beautiful reef and it was merely there for aesthetics. He would siphon out all the old sand and pour in a new bag each time he wanted to do so. In this way, his valley always had a beautiful sandy channel in the center. We tend to fill our tanks full width, where he only had a small visible section he decorated with sand.
Silicone adheres to acrylic just fine for uses like that. It's just when it has pressure on it. The rock will only have its own weight to be held up. I have used silicone against acrylic in nonpressurized applications MANY times.
I'm very impressed Marc. What are the dimensions of that MONSTER???!!!!
you can get epoxy coated magnets and just use some 2 part epoxy and glue them to the rocks. you can use standard drill bits or chip out a small area to put them. it would work great for the corners and do some rock islands. especially with the 2 sided display. (possibly see through) but, rock structures are a different blog!! (when do we get to open that one!!!)
Congrats. Looks great.
did you decide yet if you will go with a DSB with the new tank? Had a DSB in all the tanks I had so far and while I had no old tank syndrom or any crashes from a disturbed DSB.. I feel that it was not as good as it's supposed to be in dealing with phosphates or nitrates... Not sure why, could be that mine was not set properly. so I'm wondering if I should go with a SSB. Only concern is wether I should syphon the SSB or if I could leave it without having to take corals out for a weekly syphon?
Been having some corals STN and some more RTN lately and couldn't relate it to anything as all my parameters were fine with nitrates around 5. Then when I changed Nitrate testkit I got a perfect 0 even 1 day after a half full skimmer cup was accidentally dropped int eh system by a skimmer overflow. tested with a friends kit and got a nitrate reading of 40. Never imagined Nitrates to be such a silent killer as I don't see any hair alga or cyano in the tank or sump...
The magnet idea is kinda what I am thinking but magnets generally have a ferrous material that they are made from and I wouldn't want it to leach into the tank. That is why I was thinking about just using a base like http://aquaticpumpparts.com/product....6&categoryId=7 You would just have to router out a circle for the inner half to fit into and then silicone it into place. It would be a little bit of an added cost but would allow the constant adjustment we all love to have. . . don't like the rock in one place or another, Just move it. I agree that without the leather it will look weird but I am sure that another one can be found. Would have been great if Marc had gotten a few frags off of it at one point and bee able to repopulate his tank with a frag that had grown from the original. But I am sure that even with the leather it would look a little sparse with this new tank but everything will grow into it soon enough.
Even with that giant leather it would still look empty. Now there's even more real estate to add new beautiful SPS.
This thing is going to look empty without that giant leather in it. The world of reefing its opened right back up for you. You might as well just give your wallet to the fish store.
Even better, found http://www.kjmagnetics.com/proddetail.asp?prod=MMR-A-X8 which you could screw right into the rock then use another magnet or metal surface on the other side of the tank,,,
Ok first how do they mount the over flow to the side of the tank never seen one like that. Also for the rock discussion. If we are talking about a wall that wont be seen behind you could use something like http://www.kjmagnetics.com/proddetail.asp?prod=D701 Maybe embed them in a piece of acrylic, attach the flat rock to the acrylic then use other magnets on the outside of the glass to hold the rock into place..... just a thought. Its only 1/32" thick may have to use a few for bigger pieces of rock... As for the silicon not bonding to acrylic, attach acrylic rods to your sheet of acylic then drill a hole in the rock.... just brain storming... I was thinking of doing some kind of rock wall in my 55 g tank.
I mix up my own using Magnesium Chloride and Magnesium Sulfate. I'm copying Randy Holmes-Farley's Recipe #2, and I mix up a batch twice a year. It makes 1-gallon each time. I had more rock cooking forever so I really have enough, I think. I won't know until I'm stacking it... and I may add some Marco Rock after the fact.
You probably could mount the rock to acrylic but Marco Rocks suggested using silicone to attach it and acrylic does not really work to well with silicone, and I don't want to use a metal screw to try and hold it. I also want to be able to reposition a piece, maybe raise it up an inch or two or lower it down depending on what is on it and how well it has grown or is lacking growth. I also don't want to risk tearing the seals up with a piece of acrylic or eggcrate resting on them.
Marc, what product did you use to raise the mag? And I would assume that you are adding more rock than what was in the 280???
Once you get that puppy home, I'd love to see a few pics showing how they assembled that external overflow side of the tank, ie., what edge got silicone to what edge? Very interesting ........ Wonder if I could have a 400 gallon Gorilla Tank on a stand on one of the thousands of fault lines her in LA? Hmmmm, can already see an Insurance addendum needed .....
now that's a tank ...makes me want to upgrade my setup

Then it could be moved or adjusted as needed. Would be great for my tank due to 3 side viewable though one side is against a wall right now. Could you mount it to a piece of acrylic or egg crate to make a removable wall cover? Or am I not getting what you're trying to do?
