RE: Aquatic Plants Digest V3 #815

Kelly Beard is looking for a pump which will allow her to refill her tanks
from water stored in garbage cans.

I use Rubbermaid "Ruffneck" (67 L) storage containers to hold my R/O water
prior to my water changes. To get the water from the containers into my
tanks, I have an Eheim 1060 pump connected to a length of tubing. It works
nicely and is a lot easier and faster than hauling buckets of water. By
placing the pump into the tank, I can also pump old water out of the
aquarium as well. The "ease of use" of a setup such as this means that I am
a lot less likely to skip a water change due to lack of time or energy.

For really long run lengths, internal friction within the tubing will have
an effect on the volume of water which such a system can move in a given
amount of time, but I have found that the Eheim unit which I use is more
than capable of doing the job. Any increase in head pressure on the Eheim
units will just reduce the flow volume, not damage the pump mechanism. Eheim
makes a number of models, of varying capacities, and yes, they can be
expensive. But they last practically forever and Daleco currently has a sale
on all in-stock Eheim merchandise (35% off) so it might be a thought to
check them out.
