I put filter floss under the sponges to prevent sand from falling to the bottom. Used pool filtration sand and branched off from my primary pump with a valve to adjust water flow. I don't use the included pump but I don't see why you cant. Works great for me! **Q: Is the pump that it comes with a submersible or not** A: I'm confused how any pump that's not submerged would even work? That's kind of the point of the pump, to be submerged in water so that it pumps into the media... **Q: What are the exact internal diameter of the hoses?** A: From what I can measure, its 7/16 in. inner diameter and 1/2 in. outer diameter **Q: What size tubing I can use for the aquatop Mr 20 to replace the clear tubing that came with it with a black tube ?** A: 7/16 inch inner diameter, 1/2 inch outer diameter ## Frequently Bought Together - Aquatop Media Reactor, 95 GPH – Up-Flow Filtration for Water Treatment – 10-75 Gal – Adjustable Water Pump Included – Reliable Filtration System - Kolar Labs GFO Bayoxide E33 Phosphate Remover – for Freshwater and Saltwater Aquariums, Reef Tanks, Promotes Coral Health (454g) - Marineland Black Diamond Premium Activated Carbon, Filter Media For Aquariums, 40 Ounces --- ## 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.sg/products/2956419-mr-20-media-reactor-95-gph-up-flow-filtration-system](https://www.desertcart.sg/products/2956419-mr-20-media-reactor-95-gph-up-flow-filtration-system) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-20*
