Aquatop NP-302 Aquarium Submersible Pump

Wonderful little pump with a lot of power for its size. I bought to replace the air pump that came with my "HB-210: Finnex External HOB Refugium / Breeder Box + Air Pump" and this worked great. I have this pumping into the refuge and I have to turn it down slightly as if I turn it up full it tends to leak over the edge and into the tank from the side rather than the correct exit but that is also as I have about 10 lbs of live sand and rock rubble as well as each chamber is full of macro algae. I feel it had made a great little refuge on my 20 gallon nano tank and works superb for us as we cannot put a sump on this tank. One down side is sometimes the suction cups come off the tank but that could either be something I have in the tank or I have red slime algae blooms sometimes that could be causing this. Also very easy to clean, has worked perfect for about 2.5 months now with being run 24/7.

Works great in my homemade sous vide! It has ample volume, compact size, and, does't seem to be affected by the warmer water. Just keep the filter clean!

I bought this pump for a replacement to my original water pump that was in my " Fantasy Fountain". ( for those of you that don't know what a Fantasy Fountain is, get your mind out of the gutter-it's not what you're thinking. It's a watering can with a clear tube that connects to a spigot and it appears that the spigot is "floating" in the air. The water is pumped up through the clear tube, and cascades down the outside of the clear tubing from the spigot, thus making it appear as though the faucet is turned on and filling up the watering can do a web search if this is confusing, They're really cool.) Anyhoo.... this pump is better than the original! It seems to have more power than the original one did, and it runs super quiet, so the only thing you hear is the water "running" and not the sound of the pump. You have to be careful that it stays fully immersed, as you do with any submersible water pump, or the motor will burn out, so just check your water levels periodically, and you'll be fine. Highly recommend this little guy -you won't be disappointed!

I had to use silicone RTV glue to make my tubing fit, but I'm an engineer so it wasnt that hard, I was just hoping I could attach the fittings and be done. The flow valve works well but the suction cup feet sucks too hard and the glass pulls them off.

I bought this for a little swamp cooler project and it's been working just as advertised. I'll be buying another for a small fountain project. For the money I can't imagine a better option.
