Tank is shaking... What would you do?

[SPSjunky]

I recently set up a Prostar 90 V2 which is about 80 total gallon in my new-to-me house that has hardwood floors. The floors are solid, level, and in very good condition. The tank has a 36x24 footprint and I leveled the stand before putting the tank on it. The top of the tank is level as well.

When a person walks or the dogs(2 x 75lb golden marshmellow) run by the tank I can easily see the top of the taking shaking/swaying front to back and it settles out with a second or two watching from a lower angle. I wouldn't say it's extreme to the extent I'm worried about it tipping, but it's definitely noticable. The stand is the newer type that has 6 of the round feet instead of the traditional style stand that has floor contact area across the whole length of the stand.

It's enough to have me a little worried about it, and was wondering does anyone elses tank shake? Would you try relocate to a lower traffic area of the house? Does it pose a greater risk to the seams over time?

Any thoughts on it would be greatly appreciated!

I put supports under the joists to prevent this. The joists will eventually sag from the weight if you don’t support it.

My tanks do this as well and always have but only smaller tanks. My 180g and up tanks not so much. I have an IM20 in the bedroom now that the door on the stand moves enough I can hear it bumping the magnetic closer. Maybe I've just always lived in poorly constructed homes? I've never had a house built on slab, only basement or crawl space.

I would add support jacks under the floor joists around where the tank is. It will help reduce the flex in your floor. Long term movement like that will not be good for the silicone seams.

This, or put it against a load bearing wall where it is already supported.

Edited to add: this should be a small enough tank that put beside a supporting wall it should be stable, unless the house is exceptionally wobbly.

First thing I would do is recheck your leveling feet. There could be some settling and one or more may barely be contacting your floor. Next, I would check the Tank to stand to see if there were any gaps in between by using a piece of flat plastic (Thin) from a food container lid or something similar. I would also check the stand as it may be racking and need better support ( not easy to fix).

I have a prostar v2 200. The stand was wobbly at first, because the screws in the metal corner braces of the frame were ever so slightly loose. Tighten all the screws on yours and see if that makes a difference.

Thank you, that is my plan this week!
