Zoo Med Foam Block for 501 Turtle Filter

These prefilters are great. Nice surface area and durable. I use them on Aquaclear HOB filter intakes and Eheim 2215 intakes. Much better than the Fluval Edge prefilter, although I use the Edge Prefilter on my Edge due to space limitations.... The Zoo-Med is a larger diameter than the Fluval.

bought for replacements for filter used for turtle tanks. fits perfectly, last a long time. would recommend for turtle filters.

I had a small tank which I wanted an inconspicuous filter for. This filter fit the bill, being an outside the tank little canister filter. Easy and fast to set up .

I set up a couple shrimp tanks and barb breeding tanks; I bought this to cover the intake of my small canister filter to prevent fry and shrimplets from getting sucked up by the filter. It does wonders and doesn't reduce flow :)

Fits the canister well, and traps a lot of very small particles. Instructions should note that the capped end of the black tube (which is part of the filter and does not come with the replacement foam block) fits into the bottom of the sponge and that the open end of the same tube inserts into the pump opening in the top of the unit. This will force the water through the filter instead of allowing it to go around the filter instead. So, if you're using this foam block and find the water isn't quite as clean as you'd like, check to ensure the tube is in position properly and securely.
