water change in a Nano?
I have an 8 Gallon tank, and I'm afraid my python hose would drain the whole tank in a second.
I tried a water change using a mason jar ...but I'm wondering if there's a better option.
Tank has a Beta, 3 Corys, and just started with pearl weed and
(adding water via mason jar, first dose really disturbed the substrate, after that I had to sink the jar and then let the water spill out gently).
