Ok, so i have been searching the forum looking for answers but cant really find them. I am new to the forum and ponds. The house I bought has a pond I think it 1/2 acre (180 length x 90 at widest point). You can fill the pond at one end, the middle, and then the widest point (at this spot it fills from the bottom). It is about 12-15 feet deep. The previous owner had a fountain type aerator, however that recently broke off. Should i just replace that or build my own system with diffusers, something like rc51? I have attached a picture of the pond so you can get an idea of the shape. Any help would be greatly appreciated.
