Its not usually the gear you buy to run the tank that fails, its normally the owners lack of knowledge that causes the majority of problems.
Tetra make some great filters, i have two big externals myself that im very impressed with, now i've used them, i wouldnt go back to the Fluval range of canisters.
Personally rate tetras external filters highly, way above rena and fluval, although I have never used any of their air pumps, internals or heaters, so can't comment there,
Any pictures of these Tetra filters? You guys must get a very different Tetra filter (or Fluval filter) than we get over here if you like them more than Fluvals.
It looks like the Marineland C-series canister, which I can't stand. But it looks like it could be different enough to not have the issues I have seen. Either way I haven't used one so can't say much.
wow that's one powerful filter i used a bubble filter since i breeded fish in my 10 gallon and now i'm going to breed some more, maybe cory cats or platies but that's a big filter, gunna look into it more!
I guess since i posted two filters, that im saying the Tetratec is 3 times bigger than the fluval i posted about....no? Or am i getting the wrong end of the stick so to speak ?
