Good price point for size of the order. Some of the balls had what looked like some melted edges on the outer most ring, causing those particular balls to be more prone to interlocking, but overall they balls don't interlock from pouring or otherwise normal manipulation. ### ⭐⭐⭐⭐⭐ Got more than ordered great value! *by A***N on Reviewed in the United States on November 22, 2015* I ordered 400 of these and got a lot more than that. I used these in my wet dry box and they perform Great. About 350 or so fit into my box. If you use bio balls make sure you preflter heavily. ### ⭐⭐⭐⭐ Four Stars *by A***R on Reviewed in the United States on December 9, 2015* Work great however they are very expensive I will be looking for an alternative because of price --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/12040585-matenix-300-count-aquarium-filter-accessory-1-25-cubic-feet](https://www.desertcart.hr/products/12040585-matenix-300-count-aquarium-filter-accessory-1-25-cubic-feet) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-16*
