"Great filter for small tanks with all of the adjustments in all the right places."

— Alexandra

"I was really excited about finding a small Fluval filter. I have the U1s and they work well in my larger tanks. I was hoping to get these nano-filters for some tinier tanks to upgrade them, since the water flow was a selling point, and the current ones I have are weak in that department. I haven’t..."

Bottom Line

Consider alternatives if noise and vibration are a concern. It may be suitable for larger tanks but avoid for smaller or more sensitive setups. Effective filtration and customizable settings are balanced by extreme noise and vibration, especially at lower flow rates.
