I use the 2213 with glass lily pipes and it's perfect for the 60-P. I was actually thinking about throttling back the filter since it's swaying the plants a bit too much. I can't imagine having a 2217 but I'm sure some people will say they use it.
I used a 2217 on a 60P when I had it set up. With lily pipes to control the direction and dispersal of the flow, it was perfect. I had it on full blast.
Do you already have the 2217? If yes, then just throttle it back from the outflow. In New York that's too much flow IMO. :wink: Funny comparison, I have a 2215 on a 72G. I also had a 2213 on a 46G for years.
I'm not a big flow freak, but I have one on my 60p with the lily pipe on one side angled towards the front. Full blast and it's perfect. Old school eheims slow down quite a bit after they're running for a month or two.
Glad to hear that. So long as it wasn't a bunch of "No's" from everyone ill go ahead and pick it up then. I was able to get one for $100 with everything included barely used for 2 weeks after hurricane sandy. And if it is too much I'll just throw it on the 55gal.
I'm using just a regular one. From what I've heard the poppy reduces velocity more than the regular one. ADA is also coming out with a new one that is supposed to really reduce/diffuse the velocity so you can use big filters on little tanks.
"Another factor in flow rates to consider is filter media type. Biological and chemical media often work better at a rate of 4 times an hour or less. But if the flow is less than one time per hour, perhaps due to filter material being clogged, it could deprive biological media of life-giving oxygen, possibly causing a sudden release of toxins. Mechanical media, on the other hand, performs optimally with a higher flow rate, so a good balance between the two needs to be achieved depending on the media type and amount contained in the filter."
They seem to be in agreement that these extreme flows are more or less for mechanical filtration which is more important in a large fish stocked tank and reefs to move things around more compared to a planted tank that most of the filtration once mature is in the tank and only needs a gentle flow.
For filtration, I feel that bigger is better, mostly because then you don't need to add circulation pumps to get reasonable flow to all parts of the tank. I know this is kind of backwards, but I hate clutter.
Also, bigger filters tend to need to be cleaned less often. Call me an ugly American if you want, but we are talking about fish tanks, not 1950s automobiles . . .
The only issue you might have is placing the intake pipe on the 60p since the 2217 intake is 17mm and the lily pipes tend to be longer for that size. With a 13mm ADA P-2, P-4 or P-6 outflow(much better flow characteristics than the Do!aqua counterpart) and Do!aqua 17mm VV-3 intake (bigger slits than the ADA, doesn't clog as easily) you'll be set. Deciding which outflow size to go with is going to depend on your scape. The P-6 is going to be much more dispersed than the P-2 which tends to have stronger, more directed flow. Up to you though.
