Clear green or murky water, break down sludge, and prevent algal blooms in large ponds with this bundle of products.
1 x Pond Klear Xtra and 1 x Sludge Klear
Pond Klear contains millions of beneficial bacteria that target the microscopic algae and nutrients in the pond. They clump them together and sink them to the bottom of the pond, where they can be removed via the pump and filter or digested by the bacteria.
Pond Klear Xtra treats up to 100,000L
Sludge Klear is a pond sludge remover that contains millions of beneficial bacteria. Their job is to target pond sludge, break it up, and get it to the water column. From there, your filters can catch it, and it can be physically washed away. Sludge Klear will work in ponds that don’t have filters but can take longer to work as we’re relying on bacteria alone. The bacteria are capable of working at 4°C to remove sludge and improve water clarity.
6 Sludge Klear tablets treats 30,000L
