## Customer Reviews

### ⭐⭐⭐⭐⭐ Highly recommended. Great flow rate. Sturdy construction. Some noise.
*by D***N on March 16, 2019*

I purchased this pump to do automatic water changes on a saltwater tank, with the water reservoir located in the basement.The pump does make some noise (probably wouldn't want it in a living area) but it has worked well so far. Peristaltic pumps all tend to be noisy but this one's a tad louder than lower flow ones I've used in the past.This thing has a great flow rate for a peristaltic pump! The pump motor is pretty good sized and and head seems very sturdy. Other, less expensive peristaltic pumps I've used in the past have had a flimsier head that flexes/wobbles sightly as the rollers spin, but this one is rock solid. No longevity concerns.Highly recommended for those without noise concerns. I will update my review if I have any issues down the road.

### ⭐⭐⭐⭐ ball bearings but PLASTIC rollers
*by M***N on November 16, 2019*

wasn't a problem for me but might be for someone else - the rollers are plastic

### ⭐⭐⭐⭐⭐ Works great.  Good build quality.
*by I***E on June 19, 2019*

Bought this as an ATO Pump for my aquarium. It is connected to a standard 12v power supply plugged into the ATO’s relay switch (Smart AWC/ATO). It is currently pumping water effectively 5’ down, 60’ under my house, then back up 5’.I imagine you can vary the ml’s but for my case that wasn’t really important. I would guess several hundred ml’s a minute based on comparing to my other dosing pumps (which do dose precise set amounts).Any dosing pump will be loud at this flow rate and this one is no exception. At full speed you wouldn’t want it in the same room or even room adjacent.The build quality makes the Neptune DOS pumps look like a joke. Very sturdy metal roller and heads would make this ideal for an automatic water changing system.
