The Fluval G Series Hydrotech is here…
// November 19th, 2009 // Equipment Reviews, Filtration, Fluval G Series Canister Filter
The latest ‘must have’ addition to the fish room is the new Fluval G- Series filter. We recently aquired a new G-6 model for an independant technical review in our fish room.
This compact little unit is rated for superior filtration performance on a 160 gallon (600 L) at a flow rate of 265 gph (1000 L/hr). It offers the traditional mechanical and biological filtration that all fishkeepers know and love, in addition to chemical filtration, with the ability to remove nuisance compounds like nitrates and phosphates. Of particular interest is an onboard processor and sensor array that measures conductivity and temperature of the system water, storing up to 48 days worth of historical data for trending purposes. The liquid crystal display also includes counters to advise when it is time to perform maintenance on the chemical, mechanical or biological filter media.
Fluval claims that the bio-media requires maintenance at six month intervals and packages it deep inside the highly compact, low power consumption enclosure. The chemical and mechanical filter media is easily removed from access wells located on the top of the unit, eliminating the need to dismantle the filter and disrupt the bio-media. All in all the G Series looks impressive and recently there has been a lot marketing hype on the internet and the trade show circuit. Fluval has been ‘talking the the talk ‘as the next generation in aquarium filter technology- but does it ‘walk the walk?’
Over the next couple of days Sanderling will be putting this product through it’s paces, first with a documentation and set up review and then in the days and weeks that follow, we’ll measure performance, maintainability and post comments from other users. Make sure you check back on a regular basis as we drive what looks like a thoroughbred filter around the performance track !

Sanderling,
Great to finally see some hands-on information from an actual user.
I’m ready to put some money down myself, but am waiting for that extra little push before making the leap.
What size tank will you be using it on ?
One of the things of particular interest to me are the hoses and barb attachment diameters. I’ve read all the literature via PDF and it is not documented. I would like to put a Hydor ETH 300 on the output of a Fluval G6 on my 55 gallon.
I think the Hydor uses a 5/8” (16 mm) i.d. hose/barb and suspect the G6 may be similar to the Fluval 405, which is 17 mm.
*Can you please measure the hose i.d., o.d. and barb max. o.d. ?
Thanks and hurry,
Ron
Hi Ron,
The hose I measured has an internal diameter of 16mm, a wall thickness of 2 mm and an outer diameter of 24mm. The filter comes with a single length of hose, 3m long that you can fit to your specific requirements. Unlike earlier Fluval hoses, this one is a smooth walled material similar to PVC but more supple. You need to be careful to ensure that you trim it with little or no slack or it is prone to kinking, particularly on the suction side.
Jonathan
Jonathan,
Great info.
Can you verify the measurements though, they seem to be conflicting ?
Wouldn’t a 16 mm hose with 2 mm wall have a 20 mm o.d. ?

My engineering instincts overtook my dollars and sense today and I went out and purchased my own G6 from the LFS (Kee’s in Shelby Twp. MI offering generous incentives).
Using my trusty digital calipers I measured the new smooth gray tubing as follows:
I.D. = 16 mm (0.625″ = 5/8″)
O.D. = 21 mm (0.825″)
Wall = 2.5 mm (0.100″)
This I.D. should lend itself in perfect alignment with the Hydor ETH 300 in-line heater (according to their only available spec.=5/8″) !
The staff at Kee’s also made mention of the protrusion on the back rear motor housing that could be a future connection point for an add-on probe, computer connection and/or possible heater attachment, all apparent speculation or alluding by Fluval trainers.
I have just purchased a g6. For all its new technoligy i was very dissapointed with the way the aquastop valves pipe linkage, which when installing in a cupboard below the tank (which should be the easiest of places) the valve comes straight up which means that the pipes comes through the holes on the back of cabinate at the highest point possible, and are then forced to do a complete right angle to connect with the aquqvalve, this of course completely kinks the hose and is not acceptable. Quite simply the pipe conectors on valve need to be angled towards the back of filter (cabinate) instead of being straight up. I have had to remove a section of the cladding on rear of cabinate so tha i can push the filter all the way back allmost to the wall. This then allows the pipes to enter filter without kinking! My cabinate has 50cm inside height the filter is 32cm high so even with 18cm clearance for pipes and valve the pipe still kinks. I am dissapointed with the g6 for this reason after all it is a £350 filter and i would not expect one of the steps of installation to be so troublesome. Fluval realy should rethink either the type of piping they use or the design of the top of the aquavalve. I would like to replace my piece of tank rear cladding. But with current pipe and valve this i cannot do without kinking the pipes.
I had a similar issue and had to push the filter all the way to the back of the cabinet to allow the hoses to travel up behind the tank. However, I was very pleased that the hose i.d. is a standard 5/8″ and with some common fittings can be re-routed if desired or an inline heater can easily be added without the problem of using the Fluval accordian hose.
