Review on AquaClear 20 Activated Carbon Inserts 🐠 for Aquarium Filter, Replacement Media, 3-Pack - A1380 by Keegan Hillyer

This product works as described. I change mine every 30 days because they're cheap enough not to force them. Clarifies water overnight and is noticeable during use. Remember to rinse out the charcoal before putting it in the filter, otherwise your water will be full of charcoal dust. Also, be sure to remove the charcoal if you are taking medication. I will continue to buy and use this product.
