Stand Wobbling

My metal (some some type of metal) stand that sits a 38 gallon on top and 35 gallon on the bottom I have a question about. Im probably worrying over it to much but I notice if one of my cats accidental knock onto the tank the whole stand and stand will vibrate. It sounds worse then it really is, they dont topple or anything and they stop after a second or so. I dont notice any rust, bowed legs to indicate weakness or anything.

But, is there a way to tell if the stand is holding to much weight?

Static weight is not an issue, once it starts moving there are all sorts of dynamic loads applied and the stand may not be designed for much of those.

Your best bet would be to cross brace the rear to make the whole assembly more rigid. Easier said than done on a metal stand though so the best thing may be to just brace it against the wall so that it can't start moving. That's the key, don't let it start.

Im worried about putting it against the wall because the outlet is right there. It only really moves with one of the cats accidental knocks into it and it only wobbles for a second. It just made me nervous because I really dont want 50 gallons all over my floor even though its tile. This is the stand and where it sits now. Theres no where else I can put it....unless I do some serious moving and rewiring of the TV cables etc In a period of 1 weeks I would say it gets knocked maybe twice....I have yet to have my dog fly into it but I think he knows I would kill him if he touched it lol

An easy method would be to attach lengths of 2x4's against the wall horizontally, stacked to come out to the rear edge of the stand at the top. The 2x4's would extend past the stand on both sides to let you screw them to wall studs for support (lag bolts would be best but not necessarily needed as it does not need to support the weight, I like to overdo this sort of thing). Ideally the stand would be tight against the 2x4 "ledger" and you would use "L" brackets to attach the stand to this. This assembly would hold the stand stationary in two directions.

The trouble is that if the stand, being metal, keeps rocking it stresses the welded joints and they could eventually fail with catastrophic results for the glass tanks and fish.

He is dead on! a few years ago my buddy had his 80gal on a metal stand with a 29gal under. The stand was made to hold 2 tansk ofc and he had it for MANY years. about 2 years ago he noticed his stand if pushed on(or if you bumped the tank) would move a bit.. but not enough for him to be to alarmed. One day when he got off work he noticed his hole front porch wet.. when he opened his front door there layed his 80g and 29gal in pieces and 109gallons of water throughout his house. Whe we looked over his stadn we seen it finally gave out and collapsed sideways and forward. his welds begane to weaking untill it just failed.
I would keep a VERY close eye on the stand and would deff have to +1 some sort of brace system... If it was me i may opt to just build a hole new stand out of wood... but thats me :P

This has just turned me off fish completely. I rent, and the owner who is also family said the wall behind where the tank is, is cement with wood paneling and insulation. She doesnt want holes put into her walls and the tank is to heavy to put upstairs. The stand does not get knocked around much and I checked over the welds and they all appear fine.

I think I may just rehome my fish, sell the tanks and not bother. Just keep the 5.5 gallons and thats it. I have no one to build me a wood stand I will look and see if petsmart carries anything I can get cheap wood wise but if not I just dont have the skills or money to hire someone to make it so the stand doesnt fail.

Sorry to be the bearer of potentially bad news. It's one of those things that may never happen but really sucks if it does. I saw those stands when I was looking at tanks originally and decided to go with a "wood" stand, sort of an ikea affair that you put together yourself for less than $100... for one tank. They can allow for a little movement without the issue of metal fatigue.

There are easy setups that don't take any serious skills to put together. Some nice cedar finished 2x4's can easily be made up to hold one tank reasonably inexpensively, no reason it can't be setup for two. Just do a search for "DIY tank stand" here or ask for some stand ideas, strong and cheap. I've seen at least one recently.

Even if I could come up with the money to do so, it wouldnt be for another month or so. I am not sure what I could buy that could possibly hold a tank. Would a dresser be fine? Solid wood is expensive where are you finding that for under $100.....

At the fish shop. It was a simple single tank stand with two doors and a shelf underneath for a 30" tank. I think it was $80 but may have been on sale. I noted in the tank manufacturer's warranty that it stated it had to be on a stand designed specifically for aquariums. Something perhaps few know. I'd send a shot but its lights out here now.

Okay, should it be okay for a month maybe 2 months while I look around and see what I can dig up? I can only do one tank at a time so when I find one for a 40 gallon, should I move the 35 to the top or keep it on the bottom part of the stand? I will call my local fish store to see what I come up with I can also check walmart but I think their stands were for 5 and 10 gals
