Review on 🐠 Enhance Aquarium Water Quality with Fluval U Underwater Filter BioMax - A495 Replacement Filter Media by Yadira Santiago

Fluval U BioMax underwater filter works as expected with my Fluval U filters It's the largest pack I've seen so I always buy it here at Revain for the price, not the local fish shop. I have Revain Prime so I get 2 days free shipping and I don't have to pay to have my orders shipped which is great. If Fluval made them in a larger quantity I would buy these. Make sure you only remove half of the biomedium when cleaning or changing the filter to ensure you maintain adequate bacterial counts in the aquarium to keep the cycle going. Don't wash or purify your tap water or the chlorinated water will kill the beneficial bacteria, especially on the biocarriers you keep in the filter. If necessary, rinse with aquarium water. I definitely recommend these for your Fluval U underwater filter. These are the BioMax media that you use with the filter. You can also add other substances to the chamber, such as charcoal, zeo-coal, or ammonia, if needed. They are also available from Fluval and Revain. Fluval Carbon, 100g nylon bag, 3 packs Fluval Zeo-Carb, 150g, 3 packs, nylon bag Fluval Ammonia Remover, 180g nylon bag, 3 packs Make sure you are purchasing the correct BioMax biomedia. They are often mistaken for the large BioMax bio rings which do not fit or fit Fluval U-Series submersible filters.
