Eheim 2217 flow in a 30 Gallon

Hello all,

I am wanting to upgrade my Eheim 2213 to a 2217 model for my 30 gallon long planted aquarium. I know that this may seem like overkill given that the 2217 has a high flow rate. In order to combat this, I was going to extend the spray bar across a majority of the length of my tank to reduce the speed of the flow. I have slow moving Asian fish that I don't want to bother, but at the same time, I want a healthier aquarium and no powerheads in the tank. Would a Eheim 2217 on a 30 gallon be too much, or would a long spray bar be enough to spread out the flow more and allow me to have fish such as Honey Gourami? I'll also note that I'll have a Rex Grigg's CO2 reactor attached to my filter.

Just go for it and don't worry about extending the spray bar unless you absolutely want to. You can adjust the flow of the filter at the double taps.
^ exactly. And if you want to add inline stuff like a heater, reactor, etc. You will have plenty of flow.

Sounds good! It'll be nice to finally take the powerhead and CO2 lining out of the tank. Less equipment!
