Fluval filter 207 or 307

[ed gibbs]

I have a 30-35 gl tank that i will be setting up soon as a planted tank. i would like to fill it up with aprox. 40 to 50 neon and glolite tetras. I want purchase a Fluval canister filter , would the 207 be adaquit or should i go with the 307 since i would be going the 1 inch rule . Thankyou

I use a fluval 307 on my 60 gallon and  a ziss bubble filter does a great job on a 35 gallon I think the fluval 207 would be  more than adequate

I bought the 207 for my 33 gallon long. 2 months in and it seems to be doing good but I haven't ramped up the tank to a high capacity yet so I couldn’t say if a 307 would be necessary for what you want.

I have a 306 on 60gal aquarium I've been running it for 10 years now. 

The 207 will probably handle the tank and stock very well. The 307 will allow you to upgrade to a larger tank in the future (if that needs to be considered). There is a lot more room for media in 307 but it is has a higher running cost than the 207.

Sorry no straight answers from me more just thinking points to help you decide.

You can never go wrong with a larger filter. As Flumpweesel said, there is more room in the 307 for filtration media so for that reason alone it is worth the upgrade.

I use all models. 207 is fine but I always go 1 size up.You never know what the future holds. Plus if something comes up when the flow starts to slow and you can’t hit maintenance you can turn the flow up to buy some time. I’m also a fan of over filtration.  I run 107-207-307 on 20 longs depending on what I’m setting up. 29 I use a 407 because it’s guppies + others and they exponentially populate so it gives me time to grow out to take to LFS which means it gets dense in there 🤣
