Review on 🐠 Hydor Activated Carbon Canister Filter Media – Low Ash Content for Freshwater Aquariums – Ensures Crystal Clear Water – with Mesh Bag – 100 GM Pouches – 3 Count by Ginny Fidler

I ordered this filter for my Hydor 250 canister filter and followed the instructions to fit it (above the top lip) but it didn't fit properly no matter how hard I tried. The shape of the bag didn't quite match the space remaining in the filter, making sealing difficult, and this further aggravated the bead-sized leaks already emerging from the filter. I took it off feeling like I wasted my money and ended up returning the filter itself for other leakage issues. I may have done something wrong, but it seems to me that "hydor canister carbon filter" should match the hydor canister, you know?
