I think common sense plays a big role here. **Q: I would like to know the measurements of the tank that are not very obvious to me. There are more non-tank divisions** A: This kit is designed to be used with the standard 10 and 20 Gallon tanks. They should be measured with the Aqueon Tanks. 10 Gallon tanks measures "LxWxH" (20"x10"x12"). Other size options are for the 20 Gallon Tall/High (24"x12"x16") and the 20 Gallon Long (30"x12"x12"). **Q: I just received my kit for the 20 gallon long. Are there any instructions or guidelines?** A: No. Just follow the pictures. Wait! Can't really see them, huh? Getting a one-star review for lack of simple instructions. Nice clean cuts on the acrylic though. I bought one off of Ebay that had very clear and detailed instructions. It' on a piece of paper, and they just make copies. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by D***X on 6 March 2026* ### ⭐⭐⭐⭐ Almost perfect... *by A***R on 27 January 2022* ### ⭐⭐⭐⭐⭐ These dividers are great and fits perfectly. *by D***C on 5 October 2024* ## Frequently Bought Together - Bubblefin Aquarium Sump Refugium DIY Kit for Protein Skimmer Sump - Chamber dividers (20 Gallon Long) - Aqueon Silicone Sealant Clear 3 Ounces - Bubblefin Pre Sump Filter Sock Holder 4" with 2 x Filter Bags --- ## 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.us/products/189585178-aquarium-sump-refugium-diy-kit-for-portein-skimmer-sump-chamber](https://www.desertcart.us/products/189585178-aquarium-sump-refugium-diy-kit-for-portein-skimmer-sump-chamber) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-19*
