Kamoer Peristaltic FX-STP2 Dosing Pump, Updated for 2020

0

The Kamoer Peristaltic Dosing Pump has been updated for 2020 and is already in stock at authorized dealers in the US.

The now retired FX-STP dosing pump has been aptly replaced by the FX-STP2 to kick off a new decade of reefing. Built specifically for aquarium applications, the Kamoer FX-STP2 WiFi Continuous-Duty Peristaltic Dosing Pump is designed for dosing up to 24 hours a day, seven days a week. Like is predecessor,  the FX-STP2 has an adjustable flow rate dial so you can fine tune dosing fluids, aquarium supplements or effluent from a calcium reactor. The peristaltic pump will dose as small as 1 mL per minute and up to 120 mL per minute. What sets this pump apart from others is its ability to change the flow while running. The FX-STP2 WiFi is perfect for gradual, automatic water changes, sulfur denitrators, Kalkwasser reactors, and calcium reactors.

The original FX-STP dominated the peristaltic pump market in 2018 & 2019 and was considered by many to be the best continuous-duty peristaltic dosing pump on the market to date. The FX-STP2 WiFi is the second-generation of this popular dosing pump. Kamoer has expanded upon the popular features that include; quiet operation, compact size, and reliable performance.

New Features Included in the FX-STP2:

Wireless Control with Your Mobile Device

The first generation of the FX-STP Doser was controlled by turning the adjustment knob on the front of the unit. While this easy onboard control remains, you’ll now have the ability to control and monitor your FX-STP WiFi remotely using a free Kamoer Remote app that can be downloaded to Android and Apple (iOS) devices. From the app, you can see how much you are dosing, adjust dosages, check how much fluid is remaining, and more. All that is needed is a compatible mobile device and a WiFi connection.

The original FX-STP had an LCD screen to make calibration and adjustments easy. However, since the display is always on, screen life may diminish prematurely and leave you with a dark screen. Kamoer wisely added a screensaver to the FX-STP2 which dramatically increases the life expectancy of the screen. Coupled with the fact that most users will use the WiFi mobile app for status updates and fine-tuning, premature screen failure is now all but eliminated.

The FX-STP version 1 had a colorful Kamoer logo splashed across the front. The new WiFi model has a more subtle all-black variation of the company logo, which is more complementary to the industrial black and silver exterior of the doser. Kamoer also simplified the area around the adjustment knob.  They traded “Min” and “Max” text for a cleaner “-” and “+” and swapped the directional arrow for a more universally recognized volume control symbol.

Most automatic dosing pumps in the aquarium hobby are designed for intermittent use as is the case with less robust dosing pumps using DC brush-driven motors. In these sorts of low-volume applications, the doser is really only capable of running for a few minutes or maybe an hour per day at the most. Rather than occasional starts and stops, the FX-STP2 is built to run continuously for more demanding applications like feeding a calcium reactor, Kalk reactor, or for performing automatic water changes. The FX-STPs WiFi uses a high-precision stepper motor for amazingly accurate dosing no matter the rate of dosing.

Features:

  • Suitable for all sorts of continuous dosing applications
  • Ideal for feeding calcium reactors, Kalk reactors, and bio-denitrators
  • The perfect pump for building an automatic water change system
  • Memory Backup—your settings will be saved and restored if/when power lost
  • An onboard LCD display shows current pump status including flow rate and WiFi connectivity
  • Near-silent operation
  • High-precision stepper motor driver
  • Adjustable flow rate setting from 1 to 120ml/min
  • Easy to calibrate
  • Easy to replace tubing
  • Small, compact, and built tough
  • There is a downloadable quick-start guide plus a pump tutorial built into the app

The #1 Feed Pump for Calcium Reactors: Highest Rated & Most Reliable!

If you find yourself constantly having to tune your calcium reactor then you are not alone. Personally, I have used at least 5 different calcium reactors over the years and none of them would work well without the use of a peristaltic dosing pump. Other than occasionally replacing of the tubing and recalibrating to maintain accurate dosing, this is a “set it and forget it” type of solution—which is why reef hobbyists around the world love using a peristaltic dosing pump with their bio denitrator reactor and/or calcium reactor.
