Bottom trim

Hey yawl,

I found a 150G with the bottom trim for sale for supper cheap and bought it. Is this bottom trim needed for any ki d of integrety to the tank or just for show. It is just the bottom brace that the tank sits on.

That one concerns me a bit and I wouldn't use it as is without replacing the trim (fairly easy/cheap task)..
The bottom trim isn't so much structural but it does help alleviate pressure points on the glass,etc..
I would remove it and replace its functionality with a new trim or similar..

Being blunt and having fun

I would change out the trim. It will help to even out the pressure the tank will be in when full

I would remove it. As far as pressure points are concerned I would rather have the entire bottom of the tank sitting flush as opposed to 1/2" (If that) pressure points around the tank.

Figure a gallon of water weighs 8.34 pounds.. at 150 gallons that is 1248lbs.

Lets assume the tank in question is 24"H X 72"L X 18"D. If the tank were to sit with the entire bottom flush to the stand then the 1248lbs of water would be distributed among 1296in^2. So roughly a lb of water per square inch.

If the tank were to sit on a 1/2" trim outlining the bottom of the tank about 41in^2 would take a majority of the water load.

I would not use a tank that was designed with a frame without said frame. There is a reason it was put on in the first place, and I have no desire to do a leak/stress test with 150g of saltwater in my living room.

Could it be just fine? Sure. Just not in my house.

I'll try to be nice if you try to be smarter!
I can't help that I grow older, but you can't make me grow up!

Current Tank Info: 120 mixed reef with 40b sump, ASM G2 skimmer, AI Sol Blue x 2, and a 60g Frag Tank with 100g rubbermaid sump. 2 x Kessil A360w lights, no skimmer (yet)

If it had trim, it needs the trim. I would absolutely have it replaced.
