Bio Ceramic Ring is a crucial filtration medium for any aquarium setup. It efficiently removes unpleasant odors, neutralizes toxic metals, and enhances the clarity and softness of the water. DIRECTIONS Rinse thoroughly prior to use to eliminate any fine dust from handling. Place it directly into the filter chamber or inside a nylon filter bag. MAINTENANCE It is recommended to rinse it once a month using water from the aquarium. Avoid rinsing with tap water or any water that may contain chlorine; always opt for aquarium water when possible. The ceramic ring should be replaced every six months, and it's important not to change all filter media at once. Staggering the replacement of media will help maintain a stable population of beneficial bacteria.Shipping Notes

Not for side sleepers
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
These pillows are quite soft and flat, and offer very little support. I sleep on my side and can't use these pillows. I don't know why they're recommended for side sleepers.

A pillow made of extras soft lumps and clumps. Defective.
Size: Standard (Pack of 2), Style: Medium, Configuration: Pillow
This pillow should not even be sold. It's simple a super soft pillow with lumps of clumps of softness. Part of my head was even touching the mattress through the clumps. I ended up throwing it on the floor at 2 am and my head and neck hurt from it. I have never had a pillow of lumps before. I hope I can return this thing.

Super comfortable!!!!
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
They are super soft and large; they come vacuum-sealed and expand very quickly. They aren't heavy, and they are incredible for sleeping and watching TV in bed.
