Will this tank destroy my floor? (And me)

[KrisReef]

Interesting idea I'll try calling around. Might be too big compared to a gun safe

The other businesses that might be able to help are the local Fish Clubs, LFS, and Hernias are us!

I don't help lift anymore cause I got too old to be reliable.

Enjoy that new tank!

excited for you!

Got my deposit on it, now just to work out the logistics to get it. Excited to document the whole process in getting it set up.

I moved a RedSea 425XL (90gal), and that dang near killed me.... I'll never do that again.

I cannot imagine trying to wrassle that thing around.

$1000 for that tank is a steal! Congrats, and good luck getting it home and safely in place!

Ask the original owner what the dry weight was. They may know since they had to have it shipped

 

[ChrisfromBrick]

KrisReef is correct about the floor. My guess is that the legs of the stand will dent and damage the flooring. Putting some plywood underneath will definitely distribute the weight. A lot of reefers hire a moving company to move the tank.

great advice here.

Also- On a slab, there no way you are crushing it unless by chance (and you have no way of knowing it is already cracked). IMO you are fine. Like the gentleman above said, distribute the weight with some plywood.

I ran it through Chatgpt and it says it is about 1700#
Here is the info
96x30x36 tank with 1" glass hoow heavy is it


To calculate the weight of a glass aquarium, you can use the following steps:

Calculation:​

1. Determine the Volume of Glass Used:
   • Tank Dimensions: 96 inches (length) x 30 inches (width) x 36 inches (height)
   • Glass Thickness: 1 inch
2. Calculate the Surface Area:
   • Front and Back Panels: 2 panels of 96 inches x 36 inches = 6,912 square inches each = 13,824 square inches total
   • Side Panels: 2 panels of 30 inches x 36 inches = 1,080 square inches each = 2,160 square inches total
   • Bottom Panel: 96 inches x 30 inches = 2,880 square inches
   • Top Bracing (if applicable): This varies, so we’ll exclude it for simplicity.
     Total Surface Area = 13,824 + 2,160 + 2,880 = 18,864 square inches
3. Calculate the Volume of Glass:
   • Volume = Surface Area x Thickness
   • Volume = 18,864 square inches x 1 inch = 18,864 cubic inches
4. Convert Volume to Cubic Feet:
   • 1 cubic foot = 1,728 cubic inches
   • Volume in Cubic Feet = 18,864 / 1,728 ≈ 10.92 cubic feet
5. Calculate the Weight of the Glass:
   • Glass weighs approximately 157 lbs per cubic foot.
   • Weight = 10.92 cubic feet x 157 lbs/cubic foot ≈ 1,713 lbs

Final Weight Estimate:​

The estimated weight of a 96x30x36 tank with 1-inch thick glass is approximately 1,713 pounds.
This estimate only includes the glass and does not account for additional weight from water, substrate, or other components of the tank setup.

I think this math is wrong because it gets confused and multiplies the long sides by 2 twice instead of once for no apparent reason which causes it to overestimate the weight by hundreds of pounds. The volume of the front panel should be 96 in L x 36 in H x 1 in = 3456 in^3 and the back panel should also be 3456 in^3. Adding those together is 6912 in^3, not 13824 in^3.

Using a density estimate for low iron glass I found online for 158 lb/ft^3 I got a volume of ~6.9 ft^3 and a weight of ~1093 lbs for the glass alone.

I told you that there are far better resources on the forum

So someone in my community is selling their 500 gallon reef tank (96x30x36), made with 1 inch thick (starphire?) glass. I've always wanted a huge tank like this and I currently have a 100 gallon, a 60 gallon, and a 50 gallon frag tank. They're getting rid of it + all the rock and equipment for $1k, so I think I'm getting quite the deal and opportunity here.

The biggest challenge is just moving it. That much glass weighs something like 1200 pounds empty, short of finding around 15 strong guys, does anyone have advice on moving a monster tank like this?

A secondary question that my wife has brought up in concern is our flooring, we have simple pergo flooring on a concrete slab, this tank will weigh something like 6000 pounds when full, does anyone have experience or know if something this heavy would crush the flooring? I was thinking of installing some sort of foam pad underneath a 1 inch thick piece of plywood and then sit the stand on top of the plywood to help evenly distribute the weight, but would that even help?

I appreciate any insight and knowledge from those more experienced! As well as any general tips for getting into a monster tank like this.

Thank you!

Are the tank seams silicone? Back in the day, in the retail trade, we’d tell folks with glass and silicone tanks greater than 200 gallons to plan for when (not if) the seam will let go. Have manufacturers found a way around that issue? For really large tanks, DOW 795 set in a mullion works well.

Thanks for the manual math solving! The previous owner said it was about 1100-1200 pounds so I think you are spot on.

I'm not 100% on the silicone, the tank has been in the previous owners home for about 12 years. I was planning once I have it drained to take a good look at it and see if there's any sort of lifting from the silicone and potentially reseal if needed.

 

[Northern Flicker]

If it needs to be resealed anyway, I wonder if it would be easier to just move it in glass panels.

Any pics of the tank??

Any pics of the tank??

Only one I got at the moment of how the other person has it.

Stand has so basically be destroyed so I'll have to end up making something new and getting creative.
