sorry my question is not very clear i have a rondney tirnam 5500 filter and have had bacterial problems i wondered if anybody else experianced this problem
Post a picture I've never heard of one of these what sort of set up is it used on; pond freshwater trop marine or what.
Give a description of your problem as there are at least 2 forms of bacterial problem either not enough good bacteria or to much bad bacteria and whilst insufficient good bacteria can be blamed on the design of a filter and the media used to much bad bacteria in my opinion cannot as this is normally down to a failure in the maintenance regime some where i.e. insufficient water changes, over stocking, allowing the filter to clog up etc etc etc the list goes on.
