Filter Questions

Looking at the eheim classic 2213 for the 46 and the 2215 for the 72.

Is that enough, I want to simplify.

Thanks.

Canister filters are ideal because not only do they do a superb job of filtration, they also are somewhat adaptable with respect to water flow, and that is important. Different types of fish need differing levels of water current. Canisters have a spray bar which can be placed along the end wall with the holes directed against the end glass to allow a quieter flow down the tank--suitable for the forest fish we mainly keep--or remove the spray bar and use the spigot if a stronger flow is required--as for some species of fish that come from flowing rivers.

Eheims are in my view the cadillac of filters. They not only are enormously efficient and effective, they have been around for decades and have the proven reputation of reliability and durability. I have three Eheims, two of which have been running for more than 13 years non-stop with never an issue.

Other similarly-designed canisters are perhaps as efficient--I have one Rena XP3 and this seems to be so--but their longevity is yet to be determined because they are newer on the market. While initially they may be less expensive, if they need repair/replacement sooner the cost savings is gone.

I didn't check the tank rating for the models you mention, but always get the one rated for the tank, not larger; less sometimes works, if one needs very minial filtration/flow. But the newer models now have adjustment for flow which makes this rather pointless, so the one rated for the tank is best.

If the Eheim comes with all the necessary media, fine; mine didn't when I bought them. If they still don't, i would recommend cheaper media. The ceramic disks and biological media made by Fluval which is considerably less expensive, is basically the same thing. Here one can save with no repercussion.

Get 2215 for the 46g and 2217 for the 72g! Good luck

Thanks for the info.

I was hoping the 2213 & 2215 would be enough.

I picked up a 2213 today and it is very nice & simple.

I think this is fine. The 2213 is rated for up to 66g (US), the 2215 up to 90g. Don't know the difference in price, but 2 2213 might be sufficient, depending upon fish load intended for the 90g. But as I said, it is usually best to go with the recomended size. 2213 and 2215 work.

The 2215 wont be enough for the 72 gallon (or 75?) with only 164 gph flow rate! Better get 2217!. For my 75 gallon tank i would get 2217 or Fluval fx5.

I could care less about the flow rate, my 46 used to turn over 40x hour.
Been there done that. I brought it down to 10x and the fish are happier.
I am also willing to drop it to somewhere between 2-4x an hour.

I thought the 2217 could easily do a 125gal.

I just want to see what is really needed.

72gal 2215
46gal 2213
37gal keep HOB

or

72gal 2217
46gal 2215
37gal 2213

Thanks.

I was confused by the 2 2213.
I can try the recommended sizes.
Thank you for the advise.

Sorry, I was meaning you could get 2 filters 2213, one for each tank, as this one rated up to 66g is sufficient for a 70g if you intend smallish forest fish; if the tank is intended for large fish, say CA cichlids or a community of rift lake cichlids, I would go with the 2215 then. But it is still the filter rated for the tank so it will work fine.

One must remember than manufacturer's filter recommendations cannot take into account the variety of aquaria out there. Having live plants allows one to use less filtration because the plants are doing most of the work, and as you noted, fish in planted tanks generally prefer less water movement. It all comes with the territory.

I have the Eheim (or Rena) canisters rated to my 70g, 90g and 115g tanks, and I have no issues. I can reduce the flow impact as mentioned previously, and give the fish what they prefer. The heavy planting handles most of the filtration anyway.
