Tetra 41002 Stay Clean Bio-Bag Medium 8 Pack - Biodegradable Fish Tank Waste Bags for Aquarium Cleaning & Maintenance | Perfect for Freshwater & Saltwater Fish Tanks

After trying just about every fish filter you can imagine I bumped on to this one this really works well you can make your own rinse it under cold water and place it in the tank very inexpensive.It's way exactly what I needed with great priceI was having a hard time keeping my tank clear purchased these and haven't had a problem since.Super easy swap out of filters. Clean tank, equals happy fishItem was what I needed, worked well. Packaging was destroyed upon arrival....items weren’t secured in the box but rather in the bag that it came in.This actually does keep the glass cleaner. Good product. Will purchase again.Great value and you can purchase a refill pack and reuse the frame. Love it!Didn’t keep tank clean at all. The one just like it from the pet store worked. These DID NOT. Do not buy
