Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Anyone know what to do about FA

My pond needs fertilizing because it is clear all the way to the bottom. I fertilized last year but I never got a bloom. All I got out of it was lime green FA. Over the winter I stocked 10 carp.

This year I have fertilized once and the FA is already coming back. I don't really like the idea of chemicals because I understand it is only a temp fix. Then I read that the carp will only eat FA if they have no other plants to feed on. I feel like the clear water is contributing to the algae formation but I am afraid to fertilize too much because it will promote more FA.

I never knew having a nice pond was so difficult. Anybody have any suggestions??

Thanks

Have you had your water tested? What is the PH, alkalinity, etc? I'm not a pro but I think I remember reading to get a bloom you need a minimum alkalinity of 40 PPM?

If it is legal in your state, stock Tilapia at the rate of 40# per surface acre to help control the FA.

You will have to use chemicals to whack the FA before stocking the Tilapia or else they will not be able to eat the existing FA AND keep up with the new crop of FA.

Boatman, I was recently at a GA pond that has gin clear water also. His submerged plant life keeps his fish thriving. I am guessing your pond is in the northern GA mountain pine tree area. You will likely need to add 8 tom/acre of AG Lime to your water and watershed. Pine Trees create acidic soils and the pH will need to be raised to unlock the fertilizer and start a beneficial bloom.

There are also "Liquid Lime" products that are pricey compared to crushed ag lime, but can be perfect if it isn't possible to get a lime spreader truck near your pond.
