Today my pond looks like this. In a few days, it won't have all that stuff floating on top. It cycles back and forth. It will look good for 2 to 3 weeks and then slowly a film develops until it get thick like it is here. Is it due to sunny/cloudy weather? I know the water level has sure dropped since July. You see that conduit pipe, at the end of may, that's where my water was up to. That's where we stood to feed fish.

I'm not an expert but it could be an excess of nutrients. If you don't have any weeds or something to hold nutrients something has to use them, and that something is going to be algae.

if that is FA (filamentous algae) as it appears, it will sink after rain has hit it. I "think" it is because the rain knocks some of the air out of it so it sinks again. It will come back up in a couple of days, though, at it respires gases.

When I put the Tilapia in back in May, It really helped, do you think FA is growing faster than they can eat?

Dam Farm that's nasty.... lol

Do you have a air system in your pond? Doesn't look like it but just asking to make sure. I had a lot of this stuff too when I first got my pond. It took a couple years but here is what I did.

1. Got a air system up and running to help with my ponds D.O. and toxic junk on the bottom of my pond.

2. Started to put beneficial bacterial in my pond twice a year. Around May and July or August. I know some don't believe in this but combined with my air and think it has done a great job for me. I use a product called C-flo it comes in 8 disc's per package for 1 acre. I put 2 of these in a year.

3. I always use at least 2 gallons of Aqua shade one gallon around end of April first of May and then a second gallon to help maintain it. Once you put the initial amount in for your pond your supposed to help maintain it each month with a boost of AQ my pond is 1 acre so it's easy to figure out it's based on 1 acre on the jug. I believe it's 1 acre 4 foot deep and that's where most of my issue are from 1 to 4 foot or so.

Now I'm not saying any one of these things I do is the best it's just what I do and I now have no algae issues anymore. "Knock on wood" Like I said it may take a year or 2 but it worked for me.

Good Luck

Thank you RC.

No, I don't have an air system.
