Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Algae in a New Pond

I have a newly excavated 1.25 acre pond that has recently filled with some rain run-off. The pond itself was excavated 5-12' deep and up until recently was muddy and very unproductive. Our daytime and nightime temps here in CA have been mostly in the low 60's to high 40's until this week where we got into the 70's.

With the expected lack of productivity of the new pond, the muddy water and relatively low temps, I was shocked to see that I've got quite a bit of algae starting to pop up. It appears that the algae is growing on the bottom and floating up to the top? Not sure what kind.

My questions are...Is this normal, given the conditions and stage of the pond? Is something that I need to address? If so, how would you recommend addressing it?

I've recently put in the FHM and gambusia and will be putting in RES and BG soon.

I'd like to hear what the folks in the know have to say about this.

Thanks,
DD

Sound like you might have Filamentous Algae

From Aquaplant:

Filamentous algae are single algae cells that form long visible chains, threads, or filaments. These filaments intertwine forming a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae floats to the surface forming large mats, which are commonly referred to as "Pond scums." There are many species of filamentous algae and often more than one species will be present at the same time in the pond.

Does this look familiar?


Or this?

Yeah, I thought it was filamentous algae, but wasn't sure.

I just thought that this stuff was more typical of clear ponds during warmer months?

I'm getting some early algae with that 70 degree temps. Take a photo and post if you can, would help a lot.

I just got a report that my pond is in the 2nd year of early FA. It is in SW Miss., but it has been quite cold there. Dont know what's up. Last year I just had to keep raking as it released and floated, the wind pushed it to the shore.

I'd take a photo but the wind blew it up against the side.

Hopefully it doesn't get too bad.
