Tried for over an hour, would not charge.** A: I put the DE in a jar of warm water shake it up to mix it then place the filter in a large bucket that you can fill enough to submerse the filter and turn it on. Pour the de solution in and wait until the water is clear then you can use the filter in your tank. Works awesome. Make sure you have the foam ring under the filter inside the canister. **Q: what micron size does it filter? bacteria, algae, etc are too small for most filters to remove.** A: I put it in my algae bloomed tank and it fixed the problem ## Frequently Bought Together - MarineLand Magnum Polishing Internal Canister Filter, For aquariums Up To 97 Gallons, 10.5 IN (ML90770) - Marineland Micron Cartridge, Fits Magnum Canister Filters - Beaufan 4 Pack Micron Cartridge Compatible with Canister Filters & Polishing Internal Canister Filter ML90770, Compare to Part# PA0140 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/26361704-magnum-290-gph-polishing-canister-aquarium-filter-for-aquariums-up](https://www.desertcart.hr/products/26361704-magnum-290-gph-polishing-canister-aquarium-filter-for-aquariums-up) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-27*
