[AquaticLife] bio filter
You can do either. I’d try rinsing it first, in water you siphoned from the tank. NOT in fresh tap water.
If it does need to be changed, there’s a pparently a trick to it, so that you keep the bacteria you establisehd in it.
You may need to change the charcoal in the filter if you don’t need to change the filter itself.
