Installed the spray bar on my FX6 filter and noticed a big difference in water movement. My plants are thriving and the fish seem more active. Easy to attach and works well both above and below the water line.
Stewart Knox –
Great addition to my aquarium. The even water distribution helps with plant nutrient uptake and keeps the tank well-oxygenated. No issues with fit or performance after a month of use.
Carolyn Russell –
Works as expected with my FX4 filter. The oxygenation improved noticeably, especially during warmer days. Slight learning curve in positioning it correctly for optimal flow.

Perfect for a planted tank. The spray bar spreads water evenly and prevents dead spots. I’ve seen better leaf growth in my anubias and java ferns since installing it.

Solid product that fits well with my FX5. It creates a gentle current and helps with gas exchange. A little more effort is needed to adjust the height, but it’s worth it.
