Asking this because I am curious.....
Someone recently blessed me with a full box of Pro 3 Eheim sponges which consists of a piece of blue and 4 pieces of white sponges.
Happened to look behind the box and there was a chart stating the intervals of when we should change the sponges and filter media.
The chart stated that we should change two thirds of the Substrat Pro,Bio Mech and Mech Pro every 12 months.
I have been running my Pro 3 for 2 years and Ecco Pro 300 for 1 year.Never replaced anything on those 2 units except the Mech Pro for Seachem Matrix and monthly change of white sponges.
Is it really necessary to change two thirds of the filter media every 12 months?
