With a user-friendly assembly process, compact design, and durable materials, this reactor is perfect for both novice and experienced aquarium enthusiasts. ## Description Product Description Best way to diffuse the co2 into planted tanks. There is no co2 loss in this system. Inside the reactor, the co2 bubbles are broken down constantly until they´re completely dissolved into the water. When using regular (ceramic plates) diffusers, there is loss when the co2 bubbles reach the water surface. Directions Refer to the diagram and set up instructions printed on the box ## Features - MOST EFFICIENT: The Max Mix Reactor will dissolve 100% CO2 into the water. Patented impeller design completely eliminates the CO2 bubbles - EASY ASSEMBLY: No tools required for setting it up. Diagram set up instructions printed on side of box illustrates exact position of reactor - COMPACT: Makes it easy to fit exactly where you need it, internally or externally - DURABLE: Resistant to acidity and impact. Easy to clean and simple to maintain - Large size is designed for pumps from 250 to 500 GPH ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 0.05 x 0.05 x 0.05 cm; 9.07 g | | Item model number | 529 | | Item Form | Device | | Quantity | 1 | | Batteries required | No | | Batteries Included | No | | External Testing Certification | Não aplicável | | Item Weight | 9.07 g | ## Product Details - **Brand:** ISTA - **Item weight:** 0.02 Pounds - **Item form:** Device - **Manufacturer:** TopDawg Pet Supply - **Global Trade Identification Number:** 04719856835297 ## Images ![ISTA Gulfstream Tropical AGU00529 Max Mix Co2 Reactor for Aquarium, Large - Image 1](https://m.media-amazon.com/images/I/61xLEhSyQtL.jpg) ## Questions & Answers **Q: Got mine hooked up but the blades inside are not moving at all. CO2 just accumulates at the top. How do I get blades to rotate?** A: Sanding as described is a good idea ( I used 800 grit wet/dry). But the real problem is probably inside the water inlet tube where it enters the reactor body. Look into the water inlet tube; the opening at the reactor body should be perfectly round and there shouldn't be any plastic material protuding into the opening (it's particularly bad for propeller rotation if any excess material is protruding into the flow at the outside edge). My unit had about 10-15% of the diameter blocked at the outside edge - a small rat-tail file took care of that and the propellers-not-rotating-problem too. When reassembling the reactor, don't push the center tube assembly in tight - just far enough to mate the center tube with the water outlet. Then let screwing on the bottom cap push the center tube assembly into its final position. Both propellers should rattle freely after assembly. Good luck. **Q: Does this size reactor bring two suction cups like the smaller version?** A: Yes mine had 2. About a foot tall. Worked good. **Q: I see thats its mentioned they fit both 12/16 and 16/22mm, But I want to know if its 16/22mm with standard without an an adapter** A: The larger diameter is supported via really crappy adaptors. It will restrict flow very significantly. **Q: Will this work with an air pump instead of a canister filter?** A: this works with a canister filter, but not an air pump. ## Customer Reviews ### ⭐⭐⭐⭐⭐ THE BEST. *by Z***A on 18 February 2015* I'm using this mixer with internal pump 1600l/h, dissolve everything. ### ⭐⭐⭐⭐ Pretty good for the price, but needs some care when installing *by C***N on 27 April 2016* Pretty good for the price. Most likely will leak unless you take steps to prevent it.I created a full review, including video of how I prevented leaks and installation tips:[...] ### ⭐⭐⭐⭐ Does a good job *by J***R on 13 March 2017* I have this large size reactor on my Eheim 3000lph sump pump and still find I have very fine bubbles coming out of the return nozzle in the tank :( I'm sure my pump is well under the max rated lph this can take so it is a little disappointing.I found I had to use PTFE tape around the base else it leaked - the screw-oon base 'jumped' when tightening up hence the tape.I also put some air line and 1 way valve on the CO2 intake as I have a JBL inline injector, this is to stop a jet of water coming out the top!Lastly, I wouldn't trust using this outside of my sump for fear of leaks / flooding. On this subject the connections are just push fit with no barbs or way to ensure the hose stays put. You should in vest in some hose clamps on top of the PTFE if you get one! ## Frequently Bought Together - Gulfstream Tropical AGU00529 Ista Max Mix Co2 Reactor for Aquarium, Large - JARDLI Glass CO2 Drop Checker – CO2 Monitor Kit for Aquarium Planted Tank CO2 System (Drop Checker with Solution) --- ## 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.tn/products/63247665-ista-gulfstream-tropical-agu00529-max-mix-co2-reactor-for-aquarium](https://www.desertcart.tn/products/63247665-ista-gulfstream-tropical-agu00529-max-mix-co2-reactor-for-aquarium) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-11*
