Tank weight?

Any idea how to find out how much a Red Sea Reefer 250 weighs?
I'm moving and the 2nd floor is the only place for the tank.
It's 55gal with 10gal sump and about 40lbs of Rock
How would I see if that is too much for a modern townhouse 2nd floor? It was built 3 years ago
 
Should be able to get shipping weight from a retailer online and then each gal of water weighs about 8lbs.

Also note that the rock and substrate is going to displace some water, but you could go for the high end and just add them all together so you know you're safe. You're probably looking at close to 800lbs in the tank's footprint, but that's some serious guessing.

I feel you, I just put a 40gal on the 2nd floor apartment I live in and I'm still listening for creeks and thumps in the floors.

It should be enough. Seriously don't quote me on this but somewhere in life I "picked up" the info that each floor has to be able to hold 1000lbs or it's not "up-to-code" or something or rather. It kinda makes sense tho. 2 Full grown adults on a king sized bed set can weigh around 1000lbs, or even a large sofa with 3 full grown adults can weigh over 800lbs easily.
 
You really should be good tho. Contact your landlord and ask them where the floor joists are in the floor plan. Then you place is ontop of the joist (but in a certain orientation to the joist that I don't recall which is) and it's going to be the safest place to put it on that floor.
 
Yeah I was thinking.. If it was close to the limit I could paint some 3/4 wood black and make the footprint a little wider
 
The extra plywood won't really do anything to distribute the load. Is the garage ceiling open so that you can see the direction of the floor joists? As long as the tank is running perpendicular to the joists, you should be fine. I would check with the landlord to make sure you aren't violating a lease agreement though.
 
yes, if renting be sure it's ok and that you have renter's insurance to cover liability.

The tank should go perpendicular to the floor joists and you have to figure out which way they go - usually if you are on a load bearing wall you should be good. Total volume of 65 gallons isn't horrific - at first I was thinking it was 250 gallons and that had me worried!

You are probably at much higher risk of damage from a leak than from the tank crashing through the floor. Make sure you don't have any leaks anywhere. Some folks use water detecting alarms from Home Depot or Lowes. They shriek like a smoke alarm, but in response to water. Could save you a problem. Salt water leaking into wood is not a good thing, so good to be on the alert.

Lastly, I'm envious - I looked at Red Sea's site and that is a great looking tank!! Have fun with it :)
 
Water weighs about 8 lbs. per gallon. With rockwork and other things etc. you need to figure about 10 lbs. per gallon. A minimal guesstimate on the weight would be roughly 650 lbs. (not including the tank itself, or the stand). And yes floor joists need to run perpendicular to the length of the tank/stand.

The problem is not so much the floor holding the weight initially, but having it sag over time.
 
Try to position the tank near where a wall is located beneath in the garage. The further away from the wall the tank is (acting as a fulcrum) the greater the moment it creates. I have a 65 gallon on top of 16" spaced 2x10 joists with 3/4" sheathing near a steel support beam and I have not noticed any sagging.
 
The flat wall is a fire wall and is right a above the garage. Think that'll be fine?

We're talking about a 55 gallon tank - it'll be fine. Probably not any heavier than a large refrigerator. Now if it was a 250 it might be a problem.
