Reeftanknewbe, thanks, my family is fine.
All tanks up to just after WW2 were slate bottomed. Maybe the 60s, I forget when all glass came out but it was a big relief when they did as those slate bottomed tanks were sealed with alphaltium varnish which is a type of tar I think and they leaked. I had 14 of them set up at one time. Slate bottoms were invented because years ago before homes were heated, oil lamps were placed under tanks to warm them.
