For the last few months my tank has been perfectly clear and realy nice stocked clean not just a good place to fish but clean fresh and just awsome to be around. A few weeks ago I saw a little algea bolt up on some grass and structure. I use a fertalizer called perfect pond for 2 moths now. I'm not happy my tank is full of algea build up on top of the water near the bank and it's like a green cload in the middle of the tank, it stinks mesqietos are awfull and it makes me not want to spend time down there. What can I use to clear it back up with out harming my fish population. My tank is about 1 acre 15 ft deep.

Sorry for the bad grammer Im useing my I phone to post this.

likely linked to fertilizing, now it sounds like you need to thin the bloom and treat the matted algae too. Cutrine is an algaecide that is commonly used but proceed with caution, killing Phytoplankton blooms is probably the easiest way to kill fish. The product is not harmful to the fish but killing too much vegetation will consume too much O2 and cause massive fish kills. Additionally algae blooms can be squirrely, sometimes trying to thin the bloom will cause it to crash and sometimes it will cash on it's own with out treatment. You really should have someone come and look at it, even if you want to do the treatment yourself it's easier to talk with someone who has already learned the limits of what not to do. Hope that helps.

There may be another way...a natural and generally less expensive way to control the algae and the mosquitoes and return your pond to its "clean" looking state.

Stock about 10 pounds of Mozambique Tilapia. You will need to be patient, as it will take them some time to get it under control but you won't have to worry about them causing a fish kill, harming your fish, or other unintended negative consequences resulting from the use of artificial chemicals.

In addition, bluegills in your pond should control the mosquito lavae and if you have access to them Gambusia, aka mosquito fish, will also assist in controlling them.

My recipe is Cutrine Plus with a little bit of Diquat mixed in. Tilapia to handle it if and when it decides to return. And, it probably will try to return.

I'm not patient.
