We purchased the Marine Algae Cleaner after performing a test run on one of our slipways during summer 2018. The results were as such:
Previous jet wash regime of once every two weeks to remove green, slippy algae.
New jet wash regime (following application of Marine Algae Cleaner) of once every TEN weeks.
This was in contrast to another algae cleaner sample that I also ran a test on. The slipway that it has been used on has particularly aggressive algae growth which peaks during the summer. However since applying the cleaner (brushed in with a hard brush, post jet wash) it was eight weeks before a small area at the bottom of the slipway showed any signs of algae growth. From there upwards no growth had returned. Moving into a tenth week the slipway was then due for a clean. We have also used the product to clean the hull of our two patrol RIBs and navigation buoys which are pulled out of the water for maintenance. The results on the RIB hulls in particular was most worth it.
Overall the Marine Algae Cleaner is a great time saver and an easy to apply product.
