The sound of that makes me nervous. I would try to look online assuming you don't have the box to how much weight it holds and then you can calculate it that way. Each gallon of water is apx 10 pounds so you need a stand that can hold 450 pounds. I wouldn't risk it unless you do the research... you could have a huge problem to clean up!

No it will not hold the weight.
It might for a while,but eventually the legs will buckle,and you will have a huge mess.

I am not sure what you are saying. If you are looking to put 45 gallons where 30 gallons should be, I say no. Water has tremendous weight. You are talking about a 50% increase here. Please explain further.

that extra 15 gallons is an extra 125 pounds. I cant tell you if you stand can hold the extra weight or not without inspecting it.

I have a 22 gallon Tank on a table I bought from Target 15 years ago. That I put together myself. Its a basic no nothing table. The Tank itself is offset and goes over 2 inches each side of the table top.
The table is a side table or telephone stand as I purchased it.
I have had the 22 gallon tank on the table for over 10 mos and not had any issues. My fiance has a much bigger tank on a similar wood table and has had no problems either. He has a 50 gallon tank. I think most important is the stability of the stand more so than anything. If you feel that the stand is not solid to begin with then you may have a problem.

I would go to the Manufacturer Site of the Tank Stand and see if they have conditions within their products first.
First and Foremost you want to protect your Fish, so that's where I would start with the Manufacturer.

should be perfectly fine. cast iron is very durable and strong. i have a stand just like the one you are talking about that had a 38 gallon aquarium on it for 3 years with no issues, and one of the customers at the aquarium store i work at has had a 45 on the same stand for 5 years now with no problems.

It may be obvious, but besides the water's weight you need to factor in the weight of the gravel, rocks, decor & equipment. For safety's sake, it's better to use stands that are rated for weights well within your total aquarium weight. Since it's supposed to be able to take 2 tanks, it should be safe enough but note some cheap manufacturers don't really bother with stringent safety & stress-testing checks.
At least you're using a proper aquarium stand. Many people who just use some form of ordinary wooden furniture realise the furniture starts to buckle under the weight after some time. For really large tanks, it's essential to have a stand that is properly rated for that tank size and also to make sure that your flooring can take the weight. Imagine living in an apartment and waking up to find your tank has taken the most direct route down to your neighbour below!

sorry but i would not even try to put it on if it holds it will be upset

I won't say yes or no but we are talking iron here right?

And 1 tank or 2? just a 45 or 30 on bottom 45 on top?

If one 45 on a cast iron stand, ya no problem I think

If 2 tanksI think your biggest problem is the transfer of the load to the floor.

is this tank going in your basement on concrete or your bedroom? I like flat bottom stands that can spread the weight ot evenly across the bottom.

with water & gravel your at 1000 pounds which is transfered onto four 1 inch steel peg legs.

this enough pounds per square inch to be worried about I think .

As silly as it sounds call a welder and for $50 bucks he can weld a flat bottom and tell you for sure if it will hold that much weight.


I think you want to sleep easy on this one. This going wrong on a top floor of a house is easliy $5,000 in water damage and crushed floor.

Surfs up!!!

i think i have the stand you are talking about and i think not.
it's also not worth the risk
