i find that the make of a tank is irrelivant cos most of us buy tanks when they'er cheap and big. tanks are expensive and we're all looking for good deals. like me i have a tiny 12Gl tank and i got that for £7.
It's not the make it's the size and the cost that matters
Most tanks sold here are made by ALL-GLASS or Oceanic. The US has a lot of manufacturers like Krislin also, but MOST LFS carry all-glass. Of all the tanks I have, I only bought like 4 of em new. I am fortunate to live in an area where fish are popular, and I've gotten many from people gettin rid of em, or yard sales
