Review on 🌊 Active Aqua Air Pump AAPA3.2L by Hydrofarm - 1 Outlet, 2W, 3.2 L/Min, White by David Guerrero

I bought this unit to replace the exact same air pump that has been running nonstop for the past 1 year. The capacity of the old pump was reduced so much that the bubble flow was about 25% of the original capacity. I give this pump 4 stars based on its overall performance over a 12 month period. If it had taken longer I would have rated it higher. However, the power is more than enough for my 4 gallon hydro tubs. The attached diffuser is a medium sized 2 inch cylindrical diffuser. The stone is heavy enough to prevent it from floating.
