You guys have got me reading about sumps now.
So basically 70% of what they tell you at LFS is nonsense.
I was under the impression that lots of water changes will kill your fish. But I guess if you have a cycled tank. Meaning a cycled filter then you can do it.
I have a 200l plastic tank outside which I'm not using maybe I can build something with that.
Am I understanding correctly that the point of having a sump and why it is good. Is that you have "more water" in your tank.
Yes to everything you stated.
Always remember to add a Dechlorinator such as Seachem Prime or Seachem Safe.
