Longer lift tube for Aquarium Co-Op Sponge filter


Recommended Posts

A longer lift tube creates more lift.


For tall/deep aquariums; the use of lift tube extensions can be used to provide a better flow pattern.
The Hydro-Lift can be used with the 1 inch high flow outlets found on the Hydro Sponge Filter. In addition, these lifts work for both air-driven or water-driven applications.

Generally, the use of lift tube extensions can be an advantage for flow patterns, but not always, especially if upper level HOB filters are used. A deep aquarium would be just fine with short lift tube combined with a "hang-on-the-back" power filter providing upper circulation.
However if the sponge filters are your primary source of filtration, I would suggest the use of lift tube extensions for deep aquariums.

You’ll want to get an accurate measurement of the outside diameter of the existing tube, then shop for tubing that matches. You may find it sold/listed as thin-wall PVC, clear rigid tubing, or others here may have other experience/suggestions. In Canada, our Big Al’s chains sell 3-foot clear rigid tubing sections in various diameters that I have used to replace or create lift tubes in the past.
