I am ALWAYS going to want to do regular water changes and testing and all of that if I want my tank to STAY healthy.  |
Well... There are those who don't perform water changes, and some of them claim huge successes.
However a vast majority of us observe very negative results from tanks without water changes. So it's really up to the owners...what regimen to decide on, but I go with majority on this topic simply based on what can and does accumulate in our tanks and proven time after time that water changes help reduce and dilute these pathogens, waste, chemicals and minerals which can't be controlled in a closed environment (yet) when compared to 200 billion square meters of water in our oceans.
