Granites in
Glad I did it
Man, that looks almost identical to the granite I used in my stand!
Copycat
(of course, yours is a bit bigger. )As far as granite polishing, mine's been in place for about a year and a half and the granite still looks great. Haven't needed to reseal the other countertops yet either.
Love the metal stand, too. That's one of the few thing I would change if I did my tank over. Wood just takes up too much valuable real estate.
Glad to hear you were able to find enough help to get the tank inside yesterday. I couldn't make it on such short notice....

Metal stands are like Catamarans. They have great initial stability. :lol: As long as they are properly executed they can be a great space saver for sure, but not a terribly good idea in an area where earthquakes are common. Of course in FL, it's more important that the stand doesn't float away!

Wood has a lot more give & take. Believe me, when you are in a quake and watch the floor of your house undulate like an ocean wave, you learn about these things. Metal has great initial stability/strength but when force beyond its capability is applied, metal gives way in a catastrophic manner.
Take bleachers for instance. They are rated for a certain lbs. per square foot or inch but we see them collapse quite often around the world. That's because at some point they get too much weight and motion on them and they buckle. Wood tends to have much greater flexibility and resistance to catastrophic failure. If I was an engineer I would be able to give you the scientific side of what I am trying to explain. Many people still use metal stands in quake areas but I wouldn't. They believe that metal stands are stronger but that is not necessarily the case.
The point is moot in your case since you are not in a quake area and I am envious of all the room you will have under your stand. To hold the weight of that slab, the tank, rock, & water, you would need 4 x 4 wood post construction and there would be very little room under the tank. You certainly would not be able to put that giant sump under it. You made a great choice for your application for sure.

Looks Great! Really like the granite, nice touch.
Is your rock already curing? What are you going to go with? It will take a few show pieces to fill that monster up

wood may be more flexible but it is not stronger. if properly engineered, the right size, metal is superior.
they don't build bridges out of wood anymore. can you imagine the Golden Gate Bridge made of wood? even in houses here in Los Angeles when a big span or an area to carry heavy weight is wanted steel is used.
how about all those high rises in downtown Los Angeles. they are made of steel frames and they do move in a quake. couldn't be made of wood.
my house remodel is using several steel beams integrated with the wooden structure to do things that wood can't. one of those things is support the new tank, over 7,000 pounds.

Oh I hear ya. I am not in any way saying wood is better than steel for a lot of applications but there certainly is a difference in the way wood and metal react to stresses. The Golden Gate bridge is indeed made of steel, suspended from wires. High rises are also made with cement and steel cores, but are engineered to move in a quake. Many of them are on rollers or pads to help absorb quake forces. If a high rise was made of just steel set in a cement pad as many envision, it would have a fairly high probability of catastrophic failure in a quake.
My tank weighs about 14,000 lbs. and it's on wood. But, there is not much room under it and in fact I only have a couple of blowers mounted below it. However, the wood is only as good as its fasteners in the event of a quake. Your steel beams will have better fasteners and nyvp's stand is welded together so that could be considered better fasteners too. I am happy with the wood but I sure could use the space under the tank! :lol:

this is na interesting system to say the least. im glad i found the thread.
couple of thoughts. i use to run a geo thermal loup for my 180g tank. there was 2 problems with that. if i didnt run it all the time the water would go stale in it and stink. and if i did run it all the time my tank would go down to 70 deg. and to put heaters in there would cost a fortune to run and maintain 2000g of system water. my recomendation would be to make and install a diy heat exchanger between the cystern and the system. i know you said you didnt want ot do it this way but it would save you alot fo money in energy costs. florida is like a giant underground river. the water flows from one side of the state to the other. the ground temp will always be the same because of that. i think i rember some one saying that 4 ft below the ground the temp is 70-72 deg. if you ran your tank at that temp everything would be dead.
also you dont want to turn over that much water an hour. the tank would drop below optimal temps and same effect. dead fisn and corals. if you ran 500-700g an hour through a diy titanimum heat exchanger then you could turn it on and off with a controller and use a lot smaller pump to run the system. also sealing that big of a container and then pressurizing it to gravity feed it from the skimmer to the sump is not the best either. those poly tanks cant take the pressure on the lids. that is if your using a poly tank with a big lid on it.
also it would save a ton of money on water changes. to do a 10% water change on 2000g vs 1100g would be about $50 a month savings.
also the skimmer would need to be twice as big to process all that water. you need to run about 75% total system volume through your skimmer. the difference in skimmers is alot. you would nee a skimmer like bill wan has to run a 2000g system. now with a 1000g system an 18" skimmer with 1 dart pump will handle that. the difference is half the wattage. its aprox 175 watts vs 350 watts. that would be about $.75-$1 a day running cost difference in the 2 skimmers.
the tank and stand are awesome! i love the granite work. i have a piece of black silestone i thought about doing the same thing with. now i can throw that idea out the window seeing its not an original idea any more. lol
these are just some thoughts. take them with a grain of salt. its your tank and your the one who is paying for that beautiful thing. not me. :lol:
