Id doubt it. Usually tanks are standard sizes depending the size, so the base will usually match. At least that's the case in my experience, unless your tank is just taller in profile with the same size base. It all depends on shape and weight. Bc that 30 extra gallons adds some extra weight. You might could strengthen the 150 base but again id say it all depends on the size of the base. The would not want the tank sitting on the glass alone. It would need to be supported by the frame and joint of the tank. Matching up with the stand. Otherwise. It could have a stress leak. I need a tank that large lol. Hope that helps.
Not sure you will have to check the size of both.
