Ok, so I read one thing on back of filter box, and another I hear from others suggestions...wanted to clear things up!
For filters...how long do you normally keep each one before changing it? Or dose it just depend on the brand? I heard someone say dont ever throw it away because it houses important bacteria, and to just swoosh in old water to "clean" when it over flows, and filter wants to come out.
Is it usually a good month before filters "overflow & spill out of case"? Or again just depend on type. Before I returned last tanks for bigger better one...couldn't really tell if / when my Whisper filter was bad at all.
