💡 PRO TIP

The EasyClean pre-filter module can be removed and rinsed without opening the main filter 
body — do this regularly to extend the life of your Hel-X biomedia and main filter sponges. 
Rinsing in old tank water (not tap water) preserves your beneficial bacteria colony and 
keeps your biological filtration running at full capacity.
