Review on 🐠 Optimized Powkoo Intake Filter Sponge: Enhancing Aquarium Fish Tank Filtration with Sponge Filter Covers by Josh Whitehead

This product is absolute garbage. It looks like a piece of soft sponge that someone cut by hand with cheap scissors. Not worth the asking price. At 8.50 you would expect at least one product made from higher quality foam. If you have a long life filter, like most large tank canister filters, the air intake will suck in that sponge and block the water flow. which can damage the filter. The throttled filter is now unable to do its job, which can lead to ammonia spikes and dead fish. This filter may be good for cheaply mounted tail filters for small aquariums, but not for large filters.
