- App controlled automatic water changes
with built in redundancies and high quality stepper motors
that can move three times as much water as the competition
up to 32 feet vertically means reefers with bigger tanks
or filtration rooms on another floor
can finally get all the power they need
for hands-free stability.
I'm Thomas, and we're about to get hands on
with this Kamoer X2SR from its build quality and specs
to its features and the app control.
So let's dig into it.
There are a handful of auto water change systems out there
and most do a good job.
The more popular options tend to be
high quality dosing pumps paired up
with a capable aquarium controller
since they're more accurate
and carry water longer distances
than small utility pumps.
But they do have their limitations,
like their flow rate or how high or far they can pump water.
Plus they can be pretty expensive to set up
if you don't already have the controller component of it.
And then any fail safes you want to add
are all separate expenses.
Kamoer decided that repurposing a dosing pump
wasn't gonna be enough and made the purpose-built
X2 SR for tackling automatic water changes
on just about any sized home aquarium.
With a pair of larger, more powerful stepper motors,
float sensors to act as optional redundancies,
an optional built in ATO system,
plus wifi control through the Kamoer app
so that you can create your own
flexible water change schedule.
Or even just a one time water change
while also monitoring both the fresh salt water
and wastewater containers.
The specs are pretty impressive,
but before I get ahead of myself,
let's take a look at everything you get in the box.
In the box you'll find the X2 SR, the DC ATO pump,
four float sensors, four magnetic sensor mounts,
three tubing mounts, 6 meters of thick-walled
flexible tubing, 1.5 meters of clear ATO tubing,
an anti-siphon connector, the graduated cylinder
for calibration, the power supply,
some silicone grease, as well as the instruction guide.
The X2 SR here does have some stature.
Sitting it around 6.5 inches wide, 7 inches deep
and 8.75 inches tall and roughly 9 pounds,
which is no surprise when you consider
not just the metal housing,
but also those big beefy stepper motors
it uses to power the oversized dosing heads.
Those motors are capable of moving
900 milliliters per minute,
or just over 14 gallons per hour
through 3/8 inch tubing.
They're also able to move water vertically
up to 32 feet total in any combination
of pulling and pushing,
making them ideal for filtration rooms
that are not on the same floor as the display tank.
Like all stepper motors,
that power does come with a bit more noise
and these are much beefier motors.
So it is gonna be easier to hear than smaller dosing pumps.
So temper your expectations according.
But with that said, the app is incredibly flexible
and allows you to schedule at any time of the day.
So it's not too hard to just have your water
changes done when there's nobody around to hear it.
Setup is surprisingly straightforward
and the diagrams in the app
make it very easy to understand.
The tubing provided is supple and has thick walls
so it keeps its shape well.
And the dosing heads use threaded locking collars
to hold that tubing firmly in place on the heads.
And the clear tubing mounts work very nicely
to keep the tubing affixed
to panels up to 5/8 of inch thick.
I'm also pretty impressed with the float switches
and in particular, the magnetic mounts
that are included to hold them firmly in place.
The magnets themselves are completely encased in rubber,
making them waterproof,
but also provide a grippy surface
to prevent those magnets from sliding or moving around.
The ATO pump that they include is a small DC pump.
Similar to what you'll find on many other ATO setups
and is rated for 160 gallons per hour,
which should be plenty for the auto top off needs
of the majority of reefers out there.
How it works is also very easy to understand.
And just to clarify, all of those float sensors
as well as the ATO, are actually optional
and the X2 SR can operate without them.
The top pump is the drain pump
and removes the wastewater from the aquarium.
And the bottom pump is the refill pump
and adds the fresh water to the aquarium.
Both of the heads are clearly labeled with arrows
so you know which tube needs to go where.
The motors are very accurate
and can also be calibrated to ensure
they maintain that accuracy,
which is especially important
when you opt out of using those float sensors.
Speaking of which, right on the side of the unit
you'll see six ports as well as a reset button.
Starting at the top, the DC 24 volt pump port
is for the ATO pump and when in use,
will respond to the sensor plugged into liquid level.
The freshwater sensor is placed
at the bottom of the fresh saltwater bin
to notify you when it's too low.
The wastewater sensor is placed
at the top of the wastewater bin
to notify you when it is full and needs to be emptied.
The anti-overflow port is for the sensor
that's used either in the aquarium
or the sump above the water line
as a fail safe to prevent accidental overflowing.
And the DC 24 volt in is for the power supply
to provide power to the X2 SR.
There are actually two points of control for the X2 SR.
First, you've got the manual buttons on the top,
one to control each pump.
When you hold the button down,
the corresponding pump head will run until you let go.
This is really helpful for quickly priming the lines
or even for adding some fresh salt water
back to the tank manually
after you've bagged up a few fish or corals,
which is pretty convenient.
Everything else is done on the Kamoer remote app
on your smart device.
The app works well and it's pretty intuitive,
which is great to see.
I have no trouble at all finding my way around
without the manual or in-app tutorial.
The main screen will show you which sensors
you have plugged in and their current status,
as well as the status of the wastewater
and saltwater reservoirs which you can set the volumes for,
followed by the current status of the pumps
as well as the option to turn the ATO on or off.
For a reference on how to set it up physically,
you can click the information icon
at the top right hand corner to see diagrams
for both the sensors and the tubing
so that you can make sure
you've got it all set up correctly.
Under settings, you can change the name of the X2 SR
if you prefer, as well as change the pump's speed settings
which is where you'll find the option
to calibrate each of the pump heads.
Tap exchange at the bottom of the screen
and you'll be able to set the aquarium volume,
and set up a dosing schedule or a onetime water change.
The app also gives you the option
to run the heads independently
first removing water and then replacing it.
Or running both heads simultaneously
so it'll remove and replace the water at the same time,
which is actually super convenient
when you want to avoid draining the aquarium
or sump first which could cause other equipment
to become exposed to air like probes,
sensors, heaters, or pumps.
It'll also allow you to choose what days of the week
you want to perform water changes on
or set a number of days between water changes.
Then you can either choose
to build a water change schedule from scratch,
or through quick add where you can pick
the start and end times, the number of individual changes
you want to break it up into over the course of the day,
between one and 24 and the total amount of water
you want to change, either or by volume or by percentage.
You can then hit plan preview
to see the start and end time
and volumes for each point over the course of the day
and hit save to put it into action.
The app has enough flexibility
to make sure that you can get
all of the water changes your system needs completed,
while also being flexible enough
that you can schedule it when it's at least intrusive
for you and your family.
So if you have movie night on Fridays
and the tanks in the entertainment room, no problem.
Make sure the water change happens
before everyone gets home from work and school.
Is your reef aquarium in the bedroom?
No problem, schedule those water changes
during the day while you're at work.
Being able to get those frequent
and consistent water changes done automatically
without interrupting daily life is a must
for an automatic water change system.
And the X2 SR does make it really easy to accomplish.
