The 2217 has a 16/22mm intake and a 12/16mm output. Or, 5/8" / 7/8" intake and 1/2" / 5/8" output.

I don't know if there are Lily Pipe kits for the 2217. You may have to purchase the parts separately.

I have a Lily Pipe kit for a 2217 that I am not using. I don't know if I will use it any time soon. I had to put this aquarium set up on hold.

Thanks Leftc! Are you looking to sell?

I have a 2217 on my 40 gallon breeder. The planting is dense, so I decided I needed more circulation and added a 250 gph powerhead. Filter output, inlet, and power head are arranged to produce a circular pattern of flow (gyre) in the tank, as per Niko.

This has been set up for about a year, and works perfectly.

Thanks Michael! I'm trying to keep as little things as possible in the tank, hopefully I don't pass the plant density threshold! I'm in talks with a local glass shop to custom blow some lily pipes if they aren't too expensive.

You are very welcome! I might sell them.

I'm using a 2028 right now that uses 16/22mm tubing on both the intake and the output. In order for me to use them, I need to reduce the output to 12/16mm. I have the parts to do it, but I have good flow right now with what I am using (Eheim's installation kits 1 and 2). Also, I have a glass top over the aquarium. I can't use this top with the output Lily Pipe.

Hi Michael

Is your circular flow clockwise or counterclockwise?

What powerhead did you add?

I haven't seen any of niko's posts about a circular flow. Do you have any links?

Thanks! Sorry 'bout all the questions.

Hi Left C,

The circulation in my tank is clockwise, but that doesn't matter. It is set up that way because it was easier to hide the equipment on the right side of the tank.

The powerhead is a generic submersible fountain pump, the kind with suction cup feet on the bottom. It sticks to the glass on the left side so that the flow is directed along the back glass to the right.

The discussion about flow, gyre, and circulation is at http://www.aquaticplantcentral.com/f...iltration.html It's a long read, but worth it!

Thank you very much for the response, Michael.

I have my 40 breeder set up to flow in a counterclockwise direction. I have my intake and spraybar on the left side. This is the way that was shown how to set it up in an Eheim filter manual. It is not because of the Coriolis Effect.

I've added a small Rio 50 powerhead to the right side. Its feet are on its backside. It is placed on the right side pane blowing toward the left side. It flows about 60 gph or thereabouts. It is actually enough to cause the water to flow in a counterclockwise direction all by itself. This surprised me! With it turned off, I still get a counterclockwise flow from the intake and spraybar.

Thank you for the link. I'll be glad to read it.
