- Hey, it's Thomas here.
Today we are going to ban filter socks
from a reefing routine with this here,
Klir Di-4 drop-in automatic fleece roller,
and that's right,
No more washing filter socks every two to three days
and getting a bunch of bristle worm shrapnel
stuck in your fingers
or throwing them in the washing machine
and worrying about any residual soap sud
from making its way into your socks
and then wreaking havoc on your tanks.
And I mean like filter socks, not sock socks.
You know what I mean.
Filter socks have been a staple in our hobby
for a really good reason.
They trap all of that physical waste,
as soon as it enters the sump,
so we can get it the heck out of there.
The thing is, cleaning filter socks just sucks,
so they don't end up getting cleaned
nearly as often as they should,
which should be, based on our testing,
about every three days,
meaning all of that crud just ends up sitting in the water,
and it ends up breaking down anyways,
which is why automatic fleece rollers
have been steadily gaining in popularity.
The thing is, not everybody wants to do
hefty modifications to their existing sumps
to incorporate a traditional-style fleece roller
or have to go buy an entirely new sump
that already has one incorporated.
And then there's people who are doing DIY sumps
made out of like simple glass aquariums.
They'd probably like a solution too.
Klir has a fantastic solution
with their Di or drop-in automatic fleece rollers.
They're designed to fit right into
your sump's existing filter-sock section,
or if you want to make your own DIY sump,
you can even pick up a stand
that includes a quiet water-entry system
to make life even easier.
They include a quiet and robust motor,
optical water-level sensor and controller
to automatically remove that waste
as the fleece gets clogged up,
plus they include a carbon filter to absorb any smells,
which is very much appreciated.
Also, you can now hook them up to your HYDROS controller
if you have one,
which will help you eliminate the power adapter,
give you a new, more adjustable magnetic water level sensor,
and also give you more control
over how the Klir is gonna operate for your system,
so you can dial it in perfectly.
In the box, you'll find
the Klir fleece roller main housing,
the controller, the motor,
the optical sensor, the power supply,
25 yards of 50-micron filter fleece,
the large gray fresh fleece spindle,
the small white waste spindle,
two vent tubes, and two optional adapter plates.
Klir's drop-in fleece roller comes in two sizes,
a four-inch model and a seven-inch model designed to fit
most four-inch and seven-inch filter sock brackets.
We'll be focusing on the four-inch in this video,
but just about all the features will also apply
to the seven-inch model as well.
First, you'll want to be sure
to check the dimensions of your current sump,
just to make certain that it's going to be a good fit.
Measure the filter sock bracket first.
The four-inch model comes with three interchangeable plates
to fit 3.85-inch, 4-inch, and 4.25-inch diameter holders.
The four-inch is pre-installed on the Klir
and will be the one that most reefers
are gonna end up using.
You'll also need roughly 8-1/2 inches of space
below the sock holder,
which should be easy to accommodate
since most sumps are designed for socks longer than that.
Above the sock holder, you'll need an opening
with roughly 4.2 inches by 4.2 inches of clearance
and the filter sock tray will need to be able
to accommodate at least 1-1/2 inches of water depth
in order to trigger that optical sensor.
If your current sump meets those measurements,
you're good to go with the Di-4.
Now, if you have a sump
that does not have a filter sock tray,
for example, a DIY sump made out of glass aquarium,
Klir has a great water-entry system
that you can drop right in,
and not only does it hold the fleece roller,
but it also gives you fittings to attach your plumbing to
as well as a flow diverter,
so you can dial in how much of that water
goes through the fleece roller as it enters the sump.
Now, contrary to what you might assume,
the number of Klir Di-4s you will need
isn't based on how many sock holders you have.
It's actually based on the flow rate of your aquarium.
Each Di-4 is rated for up to 750 gallons per hour of flow,
so if your system is pushing 750 gallons per hour or less
through the sump, then you'll only need one,
and the extra sock holders, if you have any,
can be covered with the Klir diverter caps.
The caps also allow you to dial in
how much water you'd like to bypass the Klir
if you prefer not to cap them off completely.
If you run more than 750 gallons per hour,
you can run a pair of Klir Di-4s
linked to a single controller and optical sensor
in a mother-child configuration,
where the second unit operates off the same sensor
as the first.
How these fleece rollers work is actually really simple.
Water is going to enter the filter sock tray,
then go around, down, and inside the center of the Klir.
Then it'll flow out through the sides of the fleece,
which is gonna trap all that dirt and debris,
the uneaten food and fish poop,
just like a filter sock would.
As it gets saturated with all of that junk,
the water level's gonna rise up above the sock tray,
triggering the optical sensor.
The motor is then gonna turn the fleece,
removing the filthy fleece out of the water,
and replacing it with fresh fleece,
preventing any of that junk from breaking down in the water
and causing excess nutrients to build up,
like filter socks do when you forget to change them
after a few days or a few weeks.
No judgment here.
They absolutely suck to clean.
I totally get it.
Something totally new for Klir's drop-in fleece rollers
is their ability to be hooked up
to CoralVue's HYDROS controller.
You will need to pick up an adapter
to attach the Klir to one of the HYDROS drive ports,
which will in turn eliminate the Klir power adapter,
which is great.
You'll also want to grab yourself
a HYDROS magnetic water-level sensor
to replace the Klir's standard optical sensor.
Once you've done that, you can use your HYDROS
to control your Klir while also unlocking
a variety of extra options.
For example, the water-level sensor gives you
the ability to adjust the water depth
that triggers the motor,
which can help mitigate false readings in splashy sumps.
You can also adjust the minimum and maximum
on and off times of the motor
to dial it in perfectly to your systems,
so you use just the right amount of fleece every time.
On that note, when it does come time to replace the fleece,
you can pick up a brand-new 25-yard roll
of four-inch wide 50-micron fleece,
which also includes a new spindle for just about 14 bucks.
And depending on the size of your system,
how much livestock you have, and how heavily you feed,
it will generally last the average reefer
anywhere from one month all the way
up to three months or more.
So if you're ready to ditch the socks without the DIY hassle
and the Klir drop-in fleece roller
matches your reefing mantra,
you can pick one up for yourself by clicking right here.
