algae problems in pond

I have a terrible problem with algae in my pond this year. It has gotten so bad that today I had my helper treat the pond with 4 ounces of crystal copper sulfate. I have about a 5K or less square foot pond that is maybe three feet deep at the most and I pump fresh water into it every night. I am on a three tier electric rate system and that is when the rates are the absolute cheapest. I use a computer to control the pumping times with a dedicated 30 gpm pump in my six inch rotary drilled well. I think I will have to treat the pond multiple times to get rid of the algae, which is growing from the bottom of the pond to the surface.
Any comments are appreciated as this is the first time in 20 years I have has such a bad problem.
 
Just last week I was at a farm supply store and the owner was telling me that he'd started stocking barley straw. I asked why and he said it really helps with algae. After seeing your post just now, I Googled it:

Good luck!
 

This is what I would use in this situation as well (I own my own lake/pond herbiciding company) . It's a little less harsh on fish/tadpoles/frogs than copper for such a small area and will do the trick. They sell it in crystals as well that you can easily toss in from shore around the perimeter and get the chemical to the bottom where your problem is starting.
If you aren't concerned about fish, etc. Just up your dose of copper. 4 oz isn't enough for that size of a pond for a treatment for that much algae you are describing.
I would avoid the barley bales IMO. It does help with algae, but as it breaks down it is sucking oxygen out of the water which could cost you all other forms of life in your pond as well as turn it to look like a tea party instead of a pond.
