Here is my pond"s state about a week ago. I can't see the tiles on the bottom which is about 4 feet down. I put finer sand in the barrel filters. I've been vacuuming the bottom about once every 4 days.
I just put the UV light from my other pond in the skimmer that goes up to the fountain in the apartments. I also added more plants in the fountain because the water is getting really warm. This may be part of my algae problem.
This is another picture from my laguna set-up and the water is crystal clear. This is without the UV.
After two days with the UV in the skimmer my pool is looking much better. I'll get some pictures tomorrow.
