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. CHARACTERISTICS: The most efficient application of CO2 dissolution. The patented impeller design completely crushes the CO2 bubbles. Compact in size, and used externally. Durable to acidity and impact resistant. Designed to prevent CO2 gas from collecting at the top. Electricity is not required, since it uses the flow of water from the filter. Easy to clean and simple to maintain. Review: A well functioning product so far. - This diffuser works well. It doesn't seem to restrict my canister filter flow and it doesn't produce bubbles in the tank, like an air stone diffuser does. Also, it doesn't take up space inside of the tank. Review: Disappointed - Pro's Easy to hook into your canister filtering system. No leaks Con's The impeller doesn't spin with any reliability or at a consistent speed. I'm in the process of returning this item due to it not working properly. I am moving to a different product. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00RZZ7G3W | | Best Sellers Rank | #136,481 in Pet Supplies ( See Top 100 in Pet Supplies ) #666 in Aquarium Air Pump Accessories | | Brand | Aquarium Equip | | Brand Name | Aquarium Equip | | Customer Reviews | 3.4 out of 5 stars 49 Reviews | | Item Form | Liquid | | Item Weight | 0.65 Pounds | | Manufacturer | Aquarium Equip | | Manufacturer Part Number | FBA_I539 ISTA 12/16mm | | Model Number | FBA_I539 ISTA 12/16mm | | Number of Items | 1 | | Target Species | Aquatic Plants | | Unit Count | 1 Count | ## Product Details - **Brand:** Aquarium Equip - **Item Weight:** 0.65 Pounds - **Item Form:** Liquid - **Manufacturer:** Aquarium Equip ## Images ![ISTA Turbo CO2 Reactor Diffuser 12/16mm External for Aquarium Plants Atomizer ph - Image 1](https://m.media-amazon.com/images/I/71jFQHGlG9L.jpg) ![ISTA Turbo CO2 Reactor Diffuser 12/16mm External for Aquarium Plants Atomizer ph - Image 2](https://m.media-amazon.com/images/I/61TXqwTdt6L.jpg) ![ISTA Turbo CO2 Reactor Diffuser 12/16mm External for Aquarium Plants Atomizer ph - Image 3](https://m.media-amazon.com/images/I/3170-f7MpmL.jpg) ## Questions & Answers **Q: Is there a minimum psi that is needed for the diffusion to work? Will ehiem classic tubing fit this reactor?** A: Yes, the ehiem tubing will work. Are u hooking it up to the canister filter? If so it will work great! I have mine hooked up to a fluval 406 canister filter myself. I think it rated at 350 gph soooo I hope these helps. Plus make sure u get a bubble counter to. Very important!!! I think for the money the ista turbo is worth it. Plus it's very efficient!! I hope these helped. It the gph ,not psi. These is coming from a plumber to. My fluval is rated at 385 gph. I'm sure I'm losing 50 or so gph do to head pressure. It running a 75 gallon heavy planted aquarium, with a 30 gallon sump. **Q: Do I still need a co2 tank with this product** A: Pressurized CO2 works well at 20-30psi. Remember that this unit requires a water pump and will create back pressure on the CO2 line, and unless the DIY pressure is higher, will close your check valve. **Q: I'm running a 125 gallon tank with an ehiem canister (16/22 tubing).will this product work or will i need another size?** A: The reactor is made for 12/16mm tubing, 16/22mm tubing is too large for this reactor. I have mine hooked up to a recently established 55 gallon with a Eheim 2217. The outtake tubing on this Eheim model is 12/16 mm and works like a charm for this reactor. No leaks since intial setup weeks ago. **Q: Will this fit the flual 407 ribbed tubing?** A: Hi Lc, Thanks for your question, ISTA Turbo CO2 Reactor Diffuser is not suitable for flual 407 ribbed tubing. You need to replace the tubing used by flual 407 to 12/16mm. Thanks you Relax buty ## Customer Reviews ### ⭐⭐⭐⭐⭐ A well functioning product so far. *by H***N on August 7, 2020* This diffuser works well.

However it was made of cheap plastic and the blades in each one I owned always broke after a certain amount of time (months). It still served it's purpose. This next gen is made of a much better plastic thicker plastic. It screws on the top versus at the bottom like the old one. See the pictures for a comparison. I will say to buy 2 of the 12mm to 16mm hose adapters just incase. Plus it's to have and not need it versus need it and not have it. I used 3/8 ID 1/2 OD clear pvc tubing and used heat water to make the tubing soft enough to push the tubing on to the hose adapters. I am using this on a finnex 100 cannister filter. This reactor is doing a great job and navigating the C02 bubbles. The video I took shows you the bubbles in the water are from the plants pearling oxygen. 4 stars from me cause I had to get the adapters to hook it up to my filter and the fact that I had to look for a hose to use on to convert from 16mm to 12mm and then 12mm back to 16mm. If they would include the hose with the reactor than I would give a 5 even though I would have to purchase the adapter. Shipped from China took about 2 weeks. So I am thankful it was delivered as quick as it could get here. The last picture is of the old C02 Reactor that I has to use a fountain pump and keep the reactor submerged to avoid it leaking from the bottom. Also the old reactor did not have the secure hose connections that this one has. On a side note you need to push the hose on to the push fittings then turn the plastic hand nuts to the left. As it unscrews it bites on to the hose to hold it firmly in place. Worth my money. ## Frequently Bought Together - ISTA Turbo CO2 Reactor Diffuser 12/16mm External for Aquarium Plants Atomizer ph - Glass CO2 Drop Checker – CO2 Monitor Kit for Aquarium Tank – Functional and Reliable – Transparent Drop Checker, 4dkh/pH Reagent Solution and Suction Cup --- ## 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/12216779-ista-turbo-co2-reactor-diffuser-12-16mm-external-for-aquarium](https://www.desertcart.tn/products/12216779-ista-turbo-co2-reactor-diffuser-12-16mm-external-for-aquarium) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
