After researching peristaltic pumps why don't we (aquarium keepers) all use these for water changes on a regular basis? This system although it can be rather expensive seems like an ALMOST fool-proof way to conduct water changes. I've seen kits on amazon where the pump unit itself is only about $10!! What is the catch here? And the dosing units for reef systems seem to be a big thing... why don't we freshwater keepers have these!?!?! I mean the double unit on the link up above is $300 so I understand why not a lot of people have them but, seriously..
Exactly, any vessel that holds water will work. Essentially it has 2 rollers off the same pump - so it adds and removes water simultaneously. Meaning no guessing, etc. and unlike other peristaltic pumps it requires no calibration once you determine how much it removes initially.
The one I linked above is industrial, so it's proven - regular dosers have a limited lifespan and aren't designed to remove large volumes of liquid.
People on ReefCenral having been using the same pump with great success for 5 years or more.
