ISTA Filter Accessories Editorial Review
The ISTA I-539 External Reactor appears to be a popular choice for those looking to add CO2 to their aquariums. The product has been positively received by many customers, who say that it is easy to install and works effectively. However, there have been some concerns about the water flow rate and the need to interrupt the canister hose. Some customers have also had trouble with the reactor filling up with CO2 too quickly. It's worth noting that the product does not come with any tubing, so customers will need to purchase this separately.
