I am wonder when or how to know when to change my water in my
Azureus tank. It looks very clear and I normally have to add water to it at least one time a week. I was just wondering if I should be testing this water or changing it. My substrate is gravel with moss on top. There are pictures of the tank on my site:

Any info would be great, what type of testing would or could I do? I guess I will need to find a way to get the water out if it needs
changed...
