I have been trying to get info on when to change them and what not. Will leaving them to long build up nitrates and other harmfull stuff? How often does everyone change there media, and also is carbon needed?
Good morning NY...
I can only tell you what I've been doing with my large tanks. I change a minimum of half the water in my tanks weekly, so I don't use a lot of filtration. I don't need expensive filters just filtering tank water that's already clean.
Large and frequent water changes will do much more than carbon to maintain water quality, so I don't use it.
I use pads for the mechanical and biofiltration. The dense padding keeps the tank water crystal clear and is heavy enough to reuse by just rinsing it in old tank water. I use multiple pads and change one every couple of weeks. I don't need to change that often, but I do.
The key to a healthy tank is the water change. By flushing large quantities of clean, treated water through your tank, you guarantee the fish and plants have a clean, stable environment all the time. By following my water change routine religiously, I no longer need to test the water in my tanks, because there isn't time for toxins to build up before the next large water change.
As always, this is just one waterkeeper's opinion.
