Cleaning FW tank

[Travis32]

I currently do water changes once a week, as I only had 5 zebra danios in my 75 gallon tank. I have been doing roughly 15-20 percent. My question is when I am doing the water changes should I be digging into my sand (substrate) as well, or just emptying water? Or should I just skim the bottom and not actually dig into the substrate? Please clarify for me. Thanks

Just skim the surface and pick up any detritus you see.

You have a lot of space in that 75!

Ever thought of adding more?

Tank just finished cycling. Yesterday I just added 6 Cory catfish, but they were really small ones. I will be filling the tank up in time
