Pond Boss Forums GENERAL QUESTIONS Muddy water How long does it last (treatment) ?

Since its only been 6 days, I suggest keeping those jars on the shelf and check on them for settling.

In the meantime you might want to start reading up on treatments available. This is a good document: http://baylor.agrilife.org/files/2011/05/Control_of_Clay_Turbidity_12.pdf

To get inspired, take a new quart jar of muddy water and put a pinch of alum (from the spice dept of walmart) into it and shake it up. In a few minutes it will clump up and eventually turn gin-clear.

For doing you own testing to determine quantities of additive needed, you will need to find a very accurate scale. I used a scale in a lab at work to find it took 1.1 grams of aluminum sulfate to clear a 5 gallon bucket of water. Which worked out to 165(?) pounds to acre-ft.

You will also need to estimate the acre-ft of water in your pond.

For your original question, I don't think anyone can tell you how long the treatment will last beyond "it depends". Rainman recommended a minimum of 200 lbs per ac-ft.
