Setting up a 2.5g long. How do I filter?
I have an AC30 that would be sufficient. However, will it be too powerful. The tank is 5"Hx18"Lx7"D. So it is a relatively shallow tank. If its too powerful it'll disturb the substrate. Id like to stick to a HOB. Will the AC30 work?
If the only tool you carry is a hammer, everything starts to look like a nail.
