8" Weighted Air Stone / Disc Diffuser
These 8" weighted air stones / disc diffusers are ideal for use in koi ponds, water gardens and natural ponds. They produce fine bubbles which maximizes surface area and contact time ini the water column, with very lilttle back pressure. Made from aluminum oxide, these air stone diffusers are extremely durable, long lasting and can be repeatedly cleaned as necessary. The low profile design helps them 'diapear' in the bottom of the pond and the flat bottom design prevents them from sinking into the muck in natural ponds. These airaeration discs can be used for Aquascape Pro Air 20 & 60 Aerators, but can also be used with any medium / large air pumps.
