explain something to me

The reason they used slate on the old tanks was so they could heat them from underneath with oil burners. Glass won't hold up to the heat, and I'm guessing there would be problems with expansion & contraction having a flame on one side with cooler water on the other.

I have one of those old slate bottomed metal framed wonders. It's 5 feet long, holds 63 gallons. The thing weighs at least 200 pounds empty. I'm probably going to start working on resealing & cleaning up the frame in a week or so.

im saying the thing were he said that stainless stell will flex....to have a peice big enough not to flex it would way a tone i think they should make one out of stainless stell and have the bottom flat instead of only the edges holding it then it couldent flex and you would have less chances of breaking it .....i droped a rock by accident once and broke my sisters 10 gallon haha i told her the fish did it lol that was 6 years ago haha i was 12

hey tolak would be ace if you could post some pics of that slate bottmed tank, i never know they used to be made like that

I agree with the strength issues, also that engineering a tank with ALL glass sides would make weight and stresss distriubution better as the same tensile strength and 'flex' would occur on all sides. Making a more sound container than one with different components and compositions/properties .
