🐠 Premium 4 inch Honeycomb Design Filter Sock - Ideal for Aquariums, Ponds, Sumps/Overflows Review

They filter excellently, almost well. 130 gallon tank with Oscars pushing maybe 800 gallons an hour needs to be changed at least 1 time a day they catch it all easy to clean and dry.

Used for a 120 gallon reef aquarium and I've tried different socks to see which ones work best and they've certainly performed a lot better than the ones I got them on very easy to clean and works great.

These filter socks are awesome! I can't understand what people are saying about swimming. Mine go straight into the swamp they're destined for. Outperforms everything else. I'm buying more today.

I love that they are way better than what comes with Red Sea 170 but the only reason I gave it 4 stars is because because it doesn't fit well and doesn't fit I don't wash up in the Red Sea 170 sock making It's like I financially increase my jar stash every time I change socks and my stash stays full so it's a heavy little guy. I don't want to be sketchy, I just don't want one day my reserve to be messed up and emptied and veiled.

I use 2 of these in a 70 gallon mixed reef tank and so far they are superior to felt. Crystal clear water and a lifespan of about 5-6 days before needing to be replaced. I would give it five stars but as some have mentioned the 4 inch ring is too small and the toe floats. ***Not all made it, maybe it's quality control, but I can handle it.

The 4 inch plastic filter sock rings won't fit in my sump, actually two sumps that work in a 40 gallon and 120 gallon reef aquarium system. The sumps are made by Reef Aquatic Systems and these socks float constantly without getting stuck in rings. It was necessary to weigh them down with 8 ounces of debris to hold them in place. I reported this issue to Revain and have been a member since 2007 and this is my first negative post. Again, don't waste your money on this poor quality product.
