I wouldnt put it too high, but as long as it sits below the level of the top of the tank, it should continue easy siphon no matter what, and the pump will keep it going as long as its on.
Yeah, looked into it and they are having some qc issues, especially with the display and the pump. Ill hold off for a while.More bells and whistles that will fail in like 2 years or less.
True, but I never replace media in any of my filters now. Seems like most of the flow complaints were after a filter change and were fixed with fluval shipping a new unit. Same with the displays. Ill just stick with the fx line for now.Never had a QC issue with any of my G3's.....the reports I've read relate to some users saying they have a flow problem. That's almost always because they don't clean the filters correctly or often enough. The G3 has a filter system which allows you to flip out the cartridge and change it....in just a few seconds, without having to turn the filter off. I run Eheims in most of my other tanks and they are an excellent filter, until it comes to changing the media, which is messy and time consuming, and you have to re-prime the filter again after every use.
I suppose you pays your money and you takes your choice.
A 307 could work if your tank isn't overstocked. The 407 would be best though.
What you could do it use the 307 in addition to another filter like a $40 HOB filter or something.
The 307's pump is 300 gallons per hour which is exactly 4x your 75 gallon tank. But the reality is that the hose length and filter media will slow that down to 2x or 3x your tank size.
So if you use the 307, just cut the hoses to be as short as possible and get a HOB filter to go with it. The redundancy is good to have as well.
Definitely the 407 for 75 gallon unless you want to supplement the 307 with another filter. In fact you may end up adding to the 407. If you intend to stock heavily consider the FX4.
The 307 and the 407 are both the newest generation. However, the 407 has a higher gph filtration rate.
I use a 406 on my lightly stocked 75 g plus a 80 gallon sponge filter. But I see some using waaaay more filtration in a 75. But what I’m using seems to work fine. But a 307 is definitely not enough filtration for a 75. I’m using a 307 on my 40 g.
Thanks for the advice, I’ll take that into consideration!
Will the current be stronger with the FX4, I know it can be adjusted but I am planning on keeping small fish.
I’m a a big fan of the FX4, I have all of the 07 line and an FX4 and I love the water change help! It’s way easier than dumping water in the tankI am a total beginner about to set up a 75 gallon freshwater tank.
I was originally hoping to buy the Fluval 407 for my tank however the Fluval 307 are significantly discounted at my LFS.
Should I go for the 307 or stick with my original plan to buy the 407?
Whats the big difference between them if any, besides the 407 being the newer model?
Advice is greatly appreciated!

Thanks for the help.
My stocking plans are
-4x Honey Gourami
-11x Harlequin Rasboras
-9x Cherry Barbs
-1x Bolivian Ram
-9x Ottos
-7x JuliI Corys
Will the 407 handle this or should I go with the FX4 will the FX4 crest a strong current
at the end of the day I’m definitely more worried about the fish than the money.
Yes it is stronger flow so that is a consideration. Flow can usually be managed though, by experimenting with outlet location and direction and other means of baffling.
That's very light stocking for a 75. The 407 will be fine.
Unless your plans change in future.

A very good pointI am a fan of always going bigger. You never know down the road if you want to start adding more and more fish
Oh, good idea, thanks for the help!So I actually keep SA Cichlids so the flow is fine, when they were young I would point it at the surface and bounce it off some driftwood
I’m horrible at stocking but that looks like a moderate stocking plan for a 75 with most of the fish having a low bio load.Thanks for the help.

I recently added the 407 in place of an aqua clear 70 on a 45G with a fluval c4 hob that’s been running for several months.
The clarity change within 24 hours after the 407 was put in was incredible, even at 1/4 flow.
The 307 with a hob would likely be fine but either way the 7 canister series is amazing.

My 75 has 15 Tiger barbs and 7 Queen loaches (which are a smaller loach at 4-5 inches when grown). I plan to add 3-4 more tiger barbs whenever the color morph I’m waiting for comes in.
But if I were doing my tank over again, I would look more closely at the FX4.
But hopefully those with more experience will continue to chime in.

Gouramis do prefer minimal water movement but you should be able to baffle the flow. One of these might be an easy solution:
Flow Tamer FX for Fluval FX4/5/6 - Flow Tamer Bar
Is the water change help of the FX4 worthy of all the hype?I’m a a big fan of the FX4, I have all of the 07 line and an FX4 and I love the water change help! It’s way easier than dumping water in the tank
I have a FX4 on my 75 gallon and out of the box the current was way too strong. I added a 3 piece spray bar (first section shown in picture) and current much more manageable. I have 4 honey Gouramis and an Angel and they have no issues
Good point! Thanks for the adviceWhy not two 307s or a 307 and a 407? The redundancy won't hurt, and neither of those will require you to tinker much with flow in a 75. It will also allow you more points of flow. Just a thought.
