Recently I’m finding I have to clean my filter once a week as the sponge gets saturated in brown gunk which then reduces the flow of water from the filter. If I leave it more than a week the fish can be seen at the surface as if gasping for air.
The filter is a Rena Internal 70 Gph / 300 l/h
I've got a 92 litre tank, stocked with -
2 clown loaches
3 black widows
3 platies
3 mollies
1 algae eaters
I only feed once a day and water conditions are fine
Why does the sponge get saturated when it didn’t in the past?
Do I need a new/stronger filter? … and if so can I just replace the old one or do I need to run them together for a while for the bacteria to build up in the new filter?
Thanks
Paul
