Eheim 2213, 2215, or 2217 on 20G long?

This is TPT, you will probably get told that you need two 2217's.

For some reason that myth abounds here.

One 2213 on that tank would be more than plenty.

xmas_one is right: 2 x 2217 will be a good start.

I have a 2213 on a 29g and it's plenty of flow. Remember, you can use use the spraybar on the back or front wall, or cut it a little shorter to fit the shorter side wall. Plus you can drill holes extra holes in the bar. Lots of ways to control the direction and amount of flow to prevent dead spots.

I've got a 2232 on my 20L. It has a nice amount of flow, although I wish it was a touch higher. It's just got the regular output, no spray bar, and the circle of current just barely makes it around the tank. My tank is fairly heavily planted with a moderate sized, branchy piece of wood.

The 2232 is rated just below the 2213:
2211-60gph
2232-106gph
2213-116gph
2215-164gph

So, I would recommend the 2213 as it would probably be perfect in my setup. If you'll have more or less blocking the current then you can go up or down accordingly.

2213 definitely should be enough filtration. If you're going to be using it to also inject CO2, it may or may not be enough flow, though- depending on your setup.

+1. If you putting anything inline I would go with the 2215. The 2213 is a little weak for a 20 long IMO.

I used a 2215 even without inline stuff. 2217 is my recommendation. Future usage and ability to inline stuff, plus you can always dial it back. I've always had issues with the flow in my 20L before upgrading to a strong pump for my wet/dry. No issues since.

thanks for the replies everyone, i have no plans in the near future for anything inline, my CO2 diffuser is the atomic+ from Green Leaf,

i just want to make 100% sure im getting the best filter i can before i shell out the money, i dont mind getting the 2217 if i have to, i just dont want to create a vortex in the tank with so much flow haha.

im leaning towards the 2215 right now, but maybe you guys will steer me another way?

Another consideration is cosmetic: hose size is 1/2" on 2215 and 5/8" on 2217. Your in-line atomizer is also one of those 2 sizes.

The flow is adjustable on either Eheim: going one size up on the filter then what you think you need us likely to save you money in the long run.

Another consideration is that 2215 does not come with media baskets which will prove to be rather useful. I'm not sure on 2217.

No media baskets on 2217s, either.

Get eheim pro 2224 nearly same flow rate with 2217. Have a flow control where you can control the flow rate. That what I got for my 20G. Also come with media basket.

2213 works for me on my 20 long. It is mostly open with dwarf hair grass however. I have some "hills" in mine and I recently installed and am trying a spray bar. Using the spray bar has given me noticeably better flow over the terrain the way I have it setup. I have it at one aimed upwards to create surface turbulence along the top and a back flow is created along bottom back to the intake.

2213 . Drilled out the spray bar on mine some to cut turbulence , didn't want the fish thinking they were being flushed .

I have one 2215 on my 20 long and it is plenty. Have the spraybar on one end and a powerhead at the other to get the water going in a nice circular motion around the tank and my water is crystal clear. I see no reason to need anymore than a 2215. I even have the valve close 1/3 of the way because it was a little too powerful

I have a 2211 on a 20 long and its just enough. If I was going through a heater inline or reactor I would need a 13 or 15.

I have a 20l as well, and I am also growing hc. I presently have a aquaclear 50, hydor nano 240, and paintball co2. The co2 gets spread out pretty well, but its just to much equipment in the tank. Im trying to figure out which eheim to go with right now. I was debating between the 2211, and 2213. Im probably gonna go with an inline reactor, and glass lily pipes. I decided on the 2213, but wont get mine for about a week. We should compare, and see what works better. Our setup sounds similar

Yup. Important to separate one's need to see flow in the tank from what constitutes proper filtration. Slower flow in a canister tends to make for better biological filtration. You want a washing machine, add some powerheads.

Off subject, but besides the media that comes with the eheim cansiter. What other media do you need?

Generally (the two I have) they come with all the media you need to start unless you have something specific you want to try.
