Aquarium Advice Activist
I currently have aqua clear 402's but how long before powerheads need replacing .Mine are about 3 yrs old, used them for 2 yrs on old salt water tank. Not using then now on my fresh tank. Their in storage. Should I only need to replace the impellers occasionally or what? When I start this new tank I want to add the pre filter sponge to them, I always have a problem with them sucking up fish even when their on low.
