First off, I want to thank everyone who posts to the forums for all the knowledge you give. I have around a 3/4 acre pond where every year, it fills with algae for 3 months at a time. The past 2 years it seemed to stay all year resulting in a turnover and fish kill last year and has already turned over twice with a massive fish kill this year. So I decided to do something. I ended up purchasing a blue diamond et 120 for a great price. Buried some 3/4 inch poly pipe 160 feet to the diffuser. In the water I ziptied some 10 feet rear to the pipe and built my own pvc base and attached two vertex diffusers. So far pumping great with bo leaks. Attached are some pics. Thanks to everyone for posting on other threads.
If you pump 24/7 right off the bat it may kill fish. The toxins from the bottom come up too quick and fish can't handle that. Start slow 15min per day then slowly increase on time.
You didn't mention your depth where the disks are mounted. At about 8 feet and below the diffusers actually perform better when spaced further part than yours are. For shallow water the space you have is correct. If it isn't too hard you may want to experiment with spacing between the disks and the plume size/effectiveness
