Yes. Next time I plan on opening up and cleaning the filter is at least one year from now - or later if the flow rate is still strong. My filters are selected, filled and sized to aim for complete mineralization of organic waste. Eheims are famous for long cleaning intervals.capefeartarheel;2471296; said:What do you mean by a service interval?...does that mean thats the next time you will change the media?...and do a water change?
Thanks!
I do change water more often Right now - only lightly stocked - 100 gal every 2 weeks.
