I have a 3,000 gallon pond with plants, waterfall and fountain and recently lost 8 fish that were added about 8 weeks ago. They were doing great and growing. I noticed the water was becoming murky so I tested the water and the only issue I saw was the ammonia was just barely registering. I bought ammo lock and dosed the pond. The water is still murky and I’m unsure what’s causing that and the fish to die. Any help would be great. Thankscurrent water conditionthese fish died two days after they gathered at the waterfall and didn’t move from there. Two days after that the water became murky like the picture above.
