bought 2 of the ap100 realize these are not high dollar pumps but honestly these are the loudest pumps. One is loud the other is really loud, beyond being able to use them loud. I can hear them in my bedroom and I am hard of hearing. I would not suggest buying these pumps unless your tanks are in a separate room. Mine are in the living room and unbearable. Good airflow but man the noise.
Outstanding with 2 sponges and air stones!!! Surprisingly quite great value!
I'm going with, people complaining about the noise of this unit, had faulty units.
Far quieter than any unit I've used in it's price/performance range.
I have multiples(ap-100) and have been pleased with them. They aren't silent, but neither are Tetra or most of the others in the price range. The dual output ports is a big plus for me. You can string together a few different sponges, air stones, etc. If you have enough "t" splits, air, and check valves. Mine tend to run 3 items each. One running 4 for brine shrimp hatching.
Like the title says, it moves air really well but it’s so loud it’s not even usable. I had it running a sponge on a tank upstairs and I could hear it downstairs.
