Nina_W created the topic: Tetratec 2400

Needing a new cannister at a good price for a 500 liter aquarium, I decided to give the tetratec 2400 a try. It is trying to be a competitor for the Eheim 3 series (minus all the gadgetry) and Fluval FX5. My previous experience with cannisters have been with the extremely cheap, but not very powerful, dophin brand filters, and with the pen-plax cascade filters.

The decision to buy this cannister rested heavily on the need for something more reliable, powerful and quiet than the cascade was. Part of what tipped the scales towards the tetratec was the three year guarantee that it comes with - this is not simply a guarantee against factory errors, but a guarantee against any failure of any part of the system (minus the o-ring, and the hoses). Definitely worth taking note of.

Of course, mine leaked, even the replacement one. I suspect this is a design flaw.

What immediately impressed me about this filter is the staggering amount of media it holds. I could, in addition to the media it came with, fit the entirety of my old cascade's media into the filter trays. It does not give an indication on the box, but I would estimate it easily holds 30 liters of media.

The internal chamber is divided into four baskets that are simple to take out of the filter (they have a handle), and fit really well in the cannister. In general, this sleek filter creates the impression of a very professional machine.

It is also powerful, the box claims it does 2400 liters per hour, and the output is indeed impressive. There is a noticeable current throughout my aquarium, something I haven't seen with any other single cannister.

The 60 Watts used is fairly standard for a cannister appropriate to the aquarium size it is made for.

It was relatively easy to install, minus a few connection troubles. The hoses used are 30mm wide hoses (22mm inside diameter), allowing for a large water flow with lower pressure than is typical of the 25mm hoses most other filters use. The hoses are also a nice smokey colour that really dissapears against my black background - however, the two, 2m lengths of hose were not adequate for my long aquarium.

The hose clamps that attach the hoses to the cannister screws into a removable piece which means screwing in the hoses only needs to happen once ever. The removable piece connects with a lever. This is both a necessary feature (I strongly advise treating the hose connectors very gently) and a convenience. Unscrewing hoses was the most tedious and frustrating part of servicing my previous cannisters - this will now simply not be an issue anymore.

For the first time ever, I have more suction cups that was needed to affix the internal pipes securely. For very deep aquariums, the short pipe connecting to the inlet tube will be a frustration, however, its 30 cm length suits my setup perfectly.

The auto-start button only needed one or two presses to start the siphon, which filled up the cannister allowing for it to start up quickly and simply. Getting all the air out of the cannister, however, is not so quick or simple, and definitely contributes to the impression that this is a noisy filtration system.

Upon start up, the water level dropped markedly. Even taking into account the long hoses in use, which contributes to the amount of water the filter holds, I was quite impressed by this. Refilling shows that the filter, chock-full of media, still holds 30 liters of water. This is fantastic!

The biggest negative factor about this cannister is the weak pipe connectors. The first version came with a cracked hose clamp (which leaked - but it was replaced at no charge to me), the second one's elbow joint cracked and broke as well (but I could cludge a connection that is now working really well using a piece of the supplied hoses). The second negative point worth mentioning is that this cannister is as noisy as the cascade.

The biggest positive factors would surely the price and the sheer media capacity. It costs about a third of the retail price of an eheim, and about half of what it would cost me to buy an FX5 online. It absolutely eclipses any dophin or cascade regarding media capacity.

In conclusion, I would recommend this filter to anyone looking for a powerful machine that can hold bucketloads of media and doesn't mind it leaking.

Wonderful, concise review. But a canister that leaks isn't worth dime one. Where is it leaking from?

THOSE WHO REFUSE KNOWLEDGE ARE DOOMED TO FAIL.

WATER CHANGES ARE THE LIFEBLOOD OF THIS HOBBY. IF YOU DON'T BELIEVE SO OR SIMPLY DON'T FEEL LIKE DOING THEM, RE-HOME YOUR FISH, SELL YOUR AQUARIUM & FIND ANOTHER HOBBY, AS YOU WILL FAIL UTTERLY, COMPLETELY, & MISERABLY.

It leaked from the black connector that connects the hose connectors to the cannister... I know that doesn't sound very sensical. Tetra decided to have the hose connectors connect to a connector, that connects both hoses at once to the cannister. This thing can clip loose, for easy removal for maintenance (I guess). It also means you have to screw/uncrew the brittle connectors a bit less frequently - to make them last?
It leaks all around this thing's seams. A slow leak, and definitely not due to me plugging it in wrong, since I took it apart several times and tried it several times (once even done by Justin). If you read around the reviews, the first thing you find is the nose complaints, and then, on several, the same leak problem - hence design flaw.

It really is a slow leak, so for fishrooms (which the noise this thing makes places it in as well) it might not be as much of a problem? I don't know. Not on my hardwood floors or in my tank cabinet, thank you very much.

Shoot a pic; maybe Teflon tape will help?

returned the thing, now it's waiting for the filter I ordered online.

There's only so much aggravation one wants from your cannister - especially when the cheap dophin one you put on in the mean time connects up and starts in less than 5 minutes.

Copy that.....you should write an online review for this filter, like maybe on Amazon, so that maybe Tetra will correct the issue if enough people have the same problem.

Ever think about a Rena XP4? I have one, & love it!! (I got mine on sale for around $160)
