DP2500

Got this to help keep water circulated in my aquarium so it runs constantly and works great. Makes zero noise and moves the water well. Love the size too!

I dropped 1 star for Noise Level , It is fairly quiet but noticeable.. more of just a hum which is acceptable to me.. but not totally whisper quiet. I have it in a 75gal tank using it to pump water up about 3ft and into a 5 gallon diy canister filter. I have it turned all the way up and connected to 5/8" hose and it cleared my murky tank up in about 2 days.. ( my previous $300 name brand canister filter pump failed and I procrastinated for several months.. so water looked like dank pond water.. couldnt see in the tank.. making it spooky to feed this 15pound dinosaur.. ( snapper ) I will be happy if it lasts over 3 months.. because my expensive filter didnt last that long.. so I likely will go DIY from now on.. rather than waste hundreds on fancy filters with expensive replacement components and filter elements.. I could buy one of these for every month of the year and still not spend as much as the average canister filter setup..

Hose not included - Heads up, this pump has an unusual non-standard nozzle that does not match anything in a Home Depot. A 1/4 inch airline is too small but a 3/8 inch hose is too large. It needs a latex hose to be able to stretch over its non-barbed nozzle. I boiled water and melted a hose enough to jam it over the nozzle to be able to use the pump. Functionally it works to pump steady water into my recirculating vase aquarium about 1ft above water level and should have enough power for 2 feet if you're using a 5 gal bucket (next project). I recommend buying a pump that comes with a hose.

good quality

This is the second pump we have bought to replace the original pump for a watering fountain for our cats. The first replacement was bought over 6 years ago. We barely have to turn the pump knob up past the lowest setting to get good flow without it splashing out. It works very well for a replacement and a lot less in cost than buying a replacement from the water fountain company or a new fountain! I HIGHLY recommend these pumps for replacements. Just make sure you take it completely apart to clean it when you clean the fountain, and check your pump setting before plugging back in. Too high of a setting will make water splash out. FYI: (It can get cat hair inside and get pretty gooped up. For the health of your cat(s), clean it properly. Make sure you take it completely apart to clean it when you clean the fountain, and check your pump setting before plugging back in. Too high of a setting will make water splash out. The back only had one piece to remove, clean, rinse, let dry and replace. The front has3 pieces. The cap, the middle piece which helps keeping the knob from being turned past the high and low positions and the magnetic ‘fan’ looking piece. I remove all pieces, wash in hot soapy water, dry and reassemble, checking the position of the arrow before reassembling the entire waterbowl.)

Well, I bought the DP-2500 (550gph) pump. and it worked well for 2 months. I went out today, and it wasn't pumping although it was running. I pulled it out and the impellor broke in half. There was no debris in the pump at all.. weird... The sad part, the pump documentation that came with it said 12 month warranty, and the website listed uniclife.com doesn't exist, and there is no way to get ahold of anyone from UnicLife... Amazon says my 30 day window ran out.. So, I guess I'm screwed, and it's back to Tetra for me for a higher price.. I was gonna stock on these, but not now.

The Uniclife 80 GPH Submersible Water Pump, aye, it’s a wee beast that promises a lot but delivers in fits and starts. On the one hand, it gets the water moving, keeps the little tank or fountain from stagnating, and for that, ye cannae fault it entirely. It’s compact, easy enough to shove into place, and on the quiet side if ye’re lucky. But—and there’s always a but—it’s temperamental. Sometimes it hums along fine, other times it sputters like a drunken Glaswegian on a Friday night. The flow isn’t always consistent, and the longevity of the motor leaves ye wonderin’ how long it’ll last before it coughs its last. Three stars, because it’s serviceable for small setups and gets the basic job done, but ye’re takin’ a gamble on reliability. Not a disaster, but not the kind of pump ye brag about either.

Used the 550 GPH as a replacement pump in my inflatable spa. The pumps are known to have impeller failures and mine finally stopped working completely after 13 months of ownership. Manufacturer will not sell just the broken pump. They will only sell a whole new pump/heater/air pump as a fully assembled housing for 10x the cost of this pump. Time will tell how long this replacement will last, but if it gets anywhere near a year I'd be quite pleased.
