I have an Aquaclear 50 on my 29 gal freshwater tank. I added a pre-filter after one of my Mystery Snails got stuck on the intake. The pre-filter seems to plug pretty quickly. Is it ok to rinse it in tap water? The filter has sponge, ammonia reducing, and bio elements in it. I squeezed it out a few time in tank water, but it plugged again in 3 days. Thanks.
