I have added 10-52-4 and the clairty is perfect but what is this? "IT" is the beginning of a filamentous algae bloom. Not a good sign! When and how did you apply the 10-52-4; and what was the water-temp at that point? The water is too clear (IMO), and fertilizing may have doused the fire with gasoline.

Perfect clarity is between 18 and 24 inches. I wouldn't add more. Like Kelly says, you have tossed gas on the fire.
70 acres? That's a whopper. Did you fertilize the whole lake? What was your goal?
It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

How much of the plant material is there ? What is your alkalinity?

Besides the lake's alkalinity, your application method (literally, "how you applied it") and the applied rate-per-acre are also critical pieces of information. As a general rule, never fertilize if there's an existing "weed problem" - unless other actions are planned or in-place to manage the weeds'/algae predictable response to the introduction of more nutrients.

If I understand correctly you added 280 lbs. of fertilizer. You also state that you added 125 tons of lime earlier. If you needed lime in a 70 acre lake (not knowing your alkalinity) I would think you would need 140 tons at a minimum. You should check your alkalinity before fertilizing a lake, if it is below 20 ppm you will only benefit weeds such as the algae mats you currently have. I will sometimes fertilize a lake with some weed growth, but it depends on the type of weed and how much. Its a judgement call that I make based on my experience, but I will almost always tell a new do-it-yourself-er to get rid of any weed growth prior to fertilizing. I can't tell from the pics how bad it is, but the water looks clear and think you will have to deal with the algae now with some algicide before you proceed. Be careful though with aquatic herbicides, as you can kill fish if not properly applied. You will also need to know your alkalinity.
