I will soon be setting up a divided 10 gallon tank with a Tetra 5-15 Power Filter. This will be the first time I have ever used a filter. I know I need to baffle the filter, so I will use the tutorial for that, but how often and how much water do I need to change weekly?
I am leaving soon for USAF Basic Military Training, so I bought the larger tank and filter to make it easier for my family to care for the 2 Bettas I own. Also, I do not have enough time left to Cycle the tank, and I don't trust my family to do it themselves
