HOW CHEAP IS A FLOOD?

NOT A SINGLE SIPHON LOSS SINCE DESIGNED 30 YEARS AGO! NEED MORE BE SAID, YES... YOU NEED TO KNOW WHAT MAKES A SAFE AND RELIABLE PREFILTER BOX VS A CHEAP COPY WITH LESS FEATURES AND POOR DESIGN......DO NOT ACCEPT A CHEAP COPY AS IT IS NOT THE SAME...... WHAT MAY LOOK LIKE A SIMPLE COMPONENT, IT IS NOT. IT MUST BE DESIGNED TO RELIABLY FUNCTION WHEN POWER GOES OUT AND COMES BACK ON, WITHOUT FAILURE. AND NOT RELY ON ANOTHER CHEAP COMPONENT TO DO SO. WHY SPEND YOUR MONEY ON ALL THE OTHER COSTLY PRODUCTS ONLY TO PUT A WEAK LINK IN THE SYSTEM? THIS ITEM IS NOT ONLY A DEVICE TO GET WATER OUT OF YOUR AQUARIUM BUT IS A SAFETY DEVICE.

If your prefilter relies on this cheap pump you will have a flood. This is the weak link in your filter system safety, your systems integrity, and your floor/carpet/wood floor remaining dry. These cheap "lifter" pumps do fail and when they do you may have a sump OVERFLOW AND FLOOD

How about the "tubeless" prefilter boxes. These have even more problems..... The Lifereef Prefilter Siphon Box uses a siphon tube (Double prefilters use two) and the benefit of this is that the water velocity through the siphon tube vs a large siphon wall is much faster so no air bubbles get caught and no cheap going-to-fail air-lifter pump is needed. The siphon wall is so large in area compared to a siphon tube that you can never move the water fast enough to keep the air bubbles moving through and that cheap "lifter" pump is required or a tiny powerhead, and we know how reliable those are.


FEATURES OF ALL THE LIFEREEF PREFILTER SIPHON BOX DESIGNS:

Single Prefilter, Single Slimline Prefilter, Double Prefilter, and Double Slimline Prefilter


SLIMLINE VS STANDARD
The difference between the Slimline and Standard is the distance the prefilter box sticks out behind your aquarium: 3 1/4" for Slimline, 4 1/4" for Standard, that's it. Flow rates are identical for both, and of course the filter foam is narrower on the Slimline. If the Silencer is used the filter foam cannot, but most sumps have a mechanical filter section.
Prefilter Box, SingleSingle Prefilter Box The Single design is recommended for aquariums up to 48" long or flow rates up to 600 gph.

Available in a Single and Slimline version.

Flow rates up to 600 gph+ for both Standard and Slimline.

You DO NOT have to match your pump to the flow rate of the prefilter. These prefilters are self-governing meaning it will remove water at the exact same rate as you are pumping it into the aquarium. A ball valve or some other pump output control is required to adjust the pump output so as to not overpower the prefilter.

Outer box measures 6 1/2" wide x 11" tall

Inner box measures 8" wide x 8" tall x 3"

Required tank-to-wall clearance for Standard is 4"

Required tank-to-wall clearance for Slimline is 3 1/4"

Bonded on 1" male threaded output, 1" hosebarb connector supplied or request Vacuum Type connector

Spare Siphon Tubes $13.00
HIGHLY recommended to have a spare siphon or two on hand, they will easily break if dropped on the floor and the box refuses to function without this part. The siphon tubes will need cleaned so if you drop it, it's done.

Inner box measures 14" wide x 8" tall x 3"

Required tank-to-wall clearance for Standard is 4 1/4"

Required tank-to-wall clearance for Slimline is 3 1/4"

2x bonded on 1" male threaded outputs, 1" hosebarb connectors supplied. Vacuum style connectors available upon request.

Super Slim at 2"


The absolute narrowest the prefilter can be is 2".
This cannot use a filter foam nor can it use the Silencer. Only use this if your tank is 2" away from the wall and cannot be moved.

See Silencer photo below in Nano Prefilter Section. Photo of just the Silencer coming soon.

Lifereef Prefilter Silencer for Standard and Slimline
Not all installations will run silent so a Lifereef Silencer is offered for this purpose. You are welcome to order this with your prefilter box and if not needed you can send it back for a full refund (less shipping).
There are a number of factors that can cause any prefilter to make noise, or run silent, or somewhere in-between. You just never know until it is up and running, at various flow rates, plumbing runs, etc.
Nano-Prefilter for Nano-Aquariums of course!

Custom Euro-Rimmed Prefilters
Euro-rim Prefilter Boxes Custom made to fit your Euro rim tank.
Euro-style aquariums typically have a 3" to 5" wide rim. Prefilter boxes can be made to fit any rim width.
DETAIL PHOTOS , CUSTOMS, ETC

Details unique to all of the Lifereef Prefilter Boxes:

Outer box utilizes a one-piece "backbone" bent from 1/4" thick acrylic.

Nano boxes are 3/16" but still strong enough to handle the job.
The inner slotted box is locked in a vertical position and cannot be knocked out of alignment by fish, waves, or water currents.
Inner box can be adjusted up or down a full 1 1/2" and is held together with a strong nylon wingnut and bolt.
Others use a single or multiple holes with only a few settings and making adjustment difficult and the box can be knocked out of alignment which can lead to your sump flooding.
1" male threaded fitting is permanently bonded to the bottom and is forever leakproof (3/4" on nano-prefilters).
No gaskets or o-rings that can leak. Others use gaskets or o-rings which are susceptible to salt-creep and leaks.
Can also be ordered with an adapter for vacuum hose type installations.
CNC machined slots of uniform size and spacing for even water flow.

Tab on back of inner box slides in track in outer box to maintain a permanent vertical alignment.
Nylon thumbscrew allow the entire prefilter assembly to be aligned parallel to the aquarium back.
Colors available are blue, clear, and black.
Color has no affect on algae growth.
Clear only for RSM and BioCube prefilters, you can't see it so you don't need a color.
For aquariums with wide rims such as the Euro style aquariums we can fabricate any width. The one shown will fit over a 4 1/2" wide rim.

Contrary to what you have heard or been told you do not have to match a prefilter box with the pumps gph output. The prefilter will handle from a zero flow to its maximum flow rate, and anything in-between. In fact it is better to have a pump larger than you require and then using a ball valve (does not harm a pump to cut back flow) you can adjust to your liking.

Siphon tube prefilter boxes are preferable and SAFER to use than siphon tube-less boxes for several reasons. They are easier to clean, easier to maintain, easy to start, and do not require faulty check valves or unreliable secondary powerheads or "aquapump" to remove bubbles and air from the tube.

The water velocity through a siphon tube is faster than the water velocity through a tubeless design and therefore any bubbles generated flow right through a siphon tube. Bubbles do build up in the tubeless designs, that is why they have powerheads to hopefully keep them operating. These "tubeless" designs also pump air bubbles into your aquarium ruining the view.

Once started the siphon tube will ALWAYS restart and resume flowing water after a power failure or when you turn the pump back on. There is no need to restart the siphon tube.
