Fluval Pre-Filter Media
Fluval Pre-Filter is designed to capture solid waste before they reach other media. This prevents premature clogging of finer filters and extends their life, reducing media replacements frequency. Fluval Pre-Filter consists of inert, solid ceramic rings used to trap large and medium solid particles before they clog the finer sieves of the modules above. The diversified water flow allows establishment of biological activity on the surface of the rings, adding to the overall biological action on ammonia and nitrite

I recently purchased the Fluval Pre-Filter Media (Ceramic Rings, 26.45 oz.) for my aquarium, and I am absolutely thrilled with the results. This product has significantly improved the quality of the water in my tank, and my fish seem much happier. Here’s why I’m giving it a 5-star review:1. Superior Filtration:The ceramic rings in this pre-filter media are highly effective at trapping debris and particles before they reach the main filter. It acts as an additional layer of filtration, ensuring my tank stays clean and the water quality remains high. It’s a fantastic way to prevent the main filter from becoming clogged too quickly, which helps extend its lifespan.2. Easy to Use and Maintain:The ceramic rings are simple to rinse and replace when needed, making tank maintenance a breeze. I’ve used other types of pre-filter media before, but Fluval’s product seems to be the most efficient and easiest to handle. It doesn’t require a lot of effort to keep it in good condition.3. Excellent Water Clarity:Since adding this pre-filter media, the clarity of my tank water has dramatically improved. The rings help remove smaller particles that my main filter might miss, resulting in cleaner and clearer water overall. My fish are more visible, and the tank looks so much better.4. Safe for Fish and Plants:I love that this pre-filter media is safe for my fish and aquarium plants. The ceramic rings provide a surface area for beneficial bacteria to grow, which aids in biological filtration and helps create a healthier environment for my aquatic life.5. Durable and Long-Lasting:The Fluval ceramic rings are built to last. I’ve had them in my tank for a few weeks now, and they still look as good as new. The 26.45 oz. size is perfect for my medium-sized tank, and I’m confident it will last a long time before needing a replacement.Final Thoughts:I highly recommend Fluval Pre-Filter Media to any aquarium owner looking to improve their filtration system. The extra layer of filtration helps maintain cleaner water, and the ceramic rings are long-lasting and easy to clean. It’s a simple but effective addition to any tank, and it’s made a noticeable difference in the overall water quality.🐠 Five stars without a doubt! A must-have for healthier fish and a cleaner aquarium.

Every fluval product I have owned, it always came with the bio media. Mine last a year and a half before I had to change it. Although I did not realize it is suppose to be changed once every 6 months. Will not go so long next time.

I build my own filtration systems and these in a net bag along with filters. Great value. Very dusty compared to others I've purchased but a couple of swishes in old aquarium water and they were ready to use.

Easily fills the whole tray in my cascade can filter, id say the perfect amount, any more and it won’t fit. Always use these for the first stage of filter, lasts years and years! Simple and easy to use, just place and it’ll do the job for you. Extends the life of the sponge filter and filter floss greatly so you don’t have to clean it too often

Muy buen producto !!!! , rompe las psrticulas grandes facilitando que las esponjas las atrapen con mas facilidad !!!, al momento de lavar mi filtro canister se ve toda la suciedad que igualmente atrapan, Ojo 1 esto sirve para filtros canister o bien filtros que tengan mucho espacio y se pone a la entrada del agua Ojo 2 no es filtro biologico, si bien es ceramico, no es poroso, si frotas uno contra otro da ese sonido duro como frotar piedras nornales, no como frotar corales.

Use this in my Fluval FX6 (came recommended by turtle people & I trust Fluval) for my 125 gallon turtle tank and works like a charm. Water is clear and doesn't smell horribly (I also have purigen bags with this), I change them as they break down, which is far and few in between water changes. I'm happy with these, she is happy with them. I bought 4 boxes and only needed 2 and a half to fill the baskets, if I remember correctly. I forgot, I also mixed these with the Biomax Bio Rings, another 2 boxes. Which left them slight under filled for room for purigen bags and water movement.For anyone curious, I have the mix in all 3 baskets, then two bags in the top basket and another two in the middle). So far clear water and a not so stinky turtle!
