Hello all. I am back with a post after many years of only being a casual reader of this forum.
My pond is on the Texas gulf coast (think hot and humid!) and I've never really had a problem with too much vegetation until this year. In years past I have had some filamentous algae around the edges of the pond but that never really bothered me too much. Starting late last year I had this explosion of this growth. I think it is bottom-bearing meaning that it has roots in the bottom of the pond and therefore is throughout the water column. What is it and can I control it with tilapia? I'd rather do that than add a lot of chemical although I did treat the pond with a gallon of Cutrine Plus about a month ago but I don't think it really had an impact on this stuff.
I think I know the problem. I had an aerator going on the pond for several years but last summer it failed. I rebuilt the pump but I think when it was offline I had too much sediment build up on the diffuser and now I think it requires too much pressure to force air through the diffusers so it is ineffective. This growth took off as soon as the aerator stopped working last summer.
I also have a problem that the pond water is too clear which I guess it is clear because I have so much vegetation. I put 2 gallons of black dye in it to darken it and I am sure that it helped limit growth but this stuff grows on the surface so the black dye probably is not effective.
I am including pics of the stuff I need to eradicate.
