Thanks to the compact dimensions, it can be used both internally in the sump or externally.
The Reactor is made entirely from high quality – 100% acrylic, making it resistant to damage and discolouration.
We used a silicone seal which protects the filter against leakage. Inside the filter are sponges with a special fixture to prevent deformation of the internal sponge – it prevents also the passage of filter medium outside the filter housing (important in the case of resins or absorbers – like GFO).
Important thing is also that our media reactors are very solid and nicely made. We recommend the use of 3 Aquaforest Media, Zeo Mix, Carbon and Phosphate Minus in combination.
