Water Change fact vs fiction
Calling all Gurus, Wannabes, and PT Enthusiasts....
Everyone seems to have a different philosophy on water changes, some weekly, some monthly, and some people even every few months. I believe the Tom Barr approach was only every few months, merely with top offs in between. In my case, I do not test water parameters nor do i inject CO2; with low light and a dirt substrate. I have been doing water changes every month and a half about and haven't had any noticeable algea or other issues.
What are your takes on how often to do a water change? how much water to change out? and the logic behind your methods. Thanks guys.
