Gross!!!! This filter hasn't been cleaned in over 13 years, we had to use an excavator to clean it!!!
In this video we clean a wetland filter by removing the old gravel with an excavator and replacing it with washed roadbase. This liner pond has an intake bay and a wetland filter built with Aquascape Aquablocks, Centipede and Snorkel units.
This was so severely impacted that the only answer was to remove all the top gravel with an excavator and replace it with clean gravel.
