I am an old customer of Fukai I bought their service twice. The first product I bought around 5-6 years ago is their composite timber decking and trellis they distribute. The brand is called thenewwood. It has been around 5-6 years since the trellis and decking job is done and its quality is just as new as before. The second time, I bought anti-algae from them and magically after dropping the chemical in my pond, the algae did not grow and it lasted for 2 years. Very satisfied with Fukai.
