Easy install, works great.

These adapters are very good. They fit both my FX6 and FX4. The design, with the prefilter sponge in place, I believe allows for maximum use of the whole length of the sponge. Very nice!
I like the products but had a problem with the Fluval FX6 intake tube, the adapter and large prefilter sponge being too long and reaching the bottom of my 125 gallon tank. This makes the sponge very difficult to remove for cleaning. The sponge was basically on the substrate, so even trying to remove the adapter and sponge is difficult and I don't want to risk damaging the 3D printed adapter by removing it over and over again. The intake tube for the FX6, as far as I can figure out, can be lengthened but cannot be shortened shorter than about 9 inches because of the custom fittings. I thought I could just cut it, but that only ruined it. So, I made a short intake tube out of 3/4 inch sch 40 PVC by reducing the diameter of the ends with a metal lathe (I should paint it black!). This part could be a custom 3D printed part, but I don't have a 3D printer. I have attached a couple pictures. Thanks, Dan Brown

Junk. Cracked immediately. Make sure you save your original intake so you aren't left finding a new one.

Ordered these intake adapters back in September and it’s now December 26th. Both of the intake adapters I’ve ordered have already broken at the connection point to the intake tube on my fluvals and I had trouble with them clogging all the time since it was made with a 90 degree turn. Unfortunately unlike most of the other products here, this one I can’t recommend, your better off running a spong with no adapter.

I bought this to replace the cracked intake on my Fluval 307 and to add a pre-filter to protect my shrimp and fish. The fit is perfectly snug. The built-in offset allowed me to fit a large pre-filter sponge and use the Fluval suction cup to attach the intake tube to the wall while still having enough space around the sponge for water to move. Great addition to my Fluval filter!

Always love shopping at Aquarium Co-Op!!!!

Finally an intake solution that really is easy! A 45 second change. Big fan!!

I love that the COOP has made these. I have a 307 the medium fit great. Thanks guys

This thing is a must have for fx filters. Stops so much small debris from getting into your filter!

This is a huge improvement for the fluval 407 intake. It adjusts to the size intake sponge you use and gets rid of that floating ball that plugs up in the original fluval intake. I made a prefilter sponge for it from an old, unused, medium size sponge filter. Works great. I highly recommend this intake.

Great products

Its Great fits perfect just what I was looking for

Received product as advertised, very pleased. I have never had a bad product from aquarium coop.

Works great!

Fist well and makes changing the sponge easier.

Well made and good fit.

Snapped right on the inlet tube and was used with aquarium co-op pre filter sponge. Great combo!

Excellent upgrade kit for fluval filters. The flow you get out of these vs just alipping a sponge over the factory intake is a night and day difference.

Work great. Just what I needed :)

Works perfectly

Works perfectly! A product like this has been needed for a long time. Thank you CoOP for makingit and your dilters are perfect too

It looks so much better than the one that came with my FX4 and functions way better in my opinion

Update: I took the presponge filter off to clean it and when I went to put it back on this broke. The plastic is very thin yoj can feel when trying to put the sponge filter on and off…It is also a little too long for my 55 gallon and my fancy gf got stuck under it once, luckily I was home and watching the tank so I could rescue him.

I am going to shorten the output tube even more to prevent that from happening again..

I did shorten the tube and it was better after that until it broke.

Just a biproduct of a 3D print I suppose, but this worked well for me until I went to clean it and the pipe that sticks into the top of this, wasn't careful enough and it broke the "collar" at the top where you hook the intake pipe to. I had to use HVAC tape to keep it together, but it was broken within the first time of cleaning it.

Good product

This is a well-made product, extends the reach of the suction strainer about 3 1/2 times the manufacturers. This company also sells a sponge to cover the new strainer. Or you can just buy a sponge at your local fish store.

If you have fry and baby shrimp this is the best one to buy. And ive looked everywhere. This is the best attachment for the Fluval canister filters.
