Any advice on how to get my brown pond (looks muddy/cloudy) clearer? It has been established for approximately 5 years. I can add dye to change the color but the water still isn't clear. 1/4 acre pond- 10 ft deep in the middle.

there was a whole tiktok series of a guy doing this exact same thing and ppl crowdsourced and told him how to do it. His pond went from cloudy muck brown to almost a blue lagoon. Maybe try searching for it on there.

Powdered Gypsum is the way to go if you know for a fact the mud particles are suspended and its not catfish stirring up mud at bottom. You can get it from feed stores. I did this with my 1 acre pond that is roughly 15-20' deep at deepest point and it came out great. If I remember correctly, I spend roughly $1,000 in product and just dump it in my prop wash and made my way around my pond slowly. Took around 2 weeks to fully see effects but I had a clear view 15-20" deep.

Add a sack of lime (powder) to your pond
Example - for my pond I utilize a small boat with trolling motor and distribute the lime by hand all over the pond until the sack is empty. Then continue with my trolling motor making circles, figure 8's around the pond for mixing action.
The lime will cause the suspended solids in the water column to settle, hence clarifying the water to some degree.

Also, if it is brown turbidity, there's only two causes.

1: Already mentioned, wildlife/livestock constantly stirring up the bottom

2: Muddy runoff and nearby erosion in the drainage basin.

For #2, you want a healthy amount of grass/plant growth all around the pond, except on the dam, you want grass/weeds but nothing shrubby or woody (roots will destroy your dam).

How about some pics of your pond?

The dye is only to prevent algae blooms by diminishing the amount of sunlight that can penetrate through the water column. With your turbidity, you don't need dye, the water is already cloudy with clay particles. If at some point you do get your water crystal clear, that's when you'd look at dyes to prevent the algae getting out of control.

Let's do a water swap. My pond is so clear the bass just look at me fishing and laugh.

We use AG lime sprayed directly off of flat bed trailer with a hose. Takes hours but it’s kinda satisfying. It’ll end up clearing our whole pond. About 1-1.25 acres in size. Now our pond is clear enough grasses grow and we use pond dye to knock that back. The AG lime lasts a few years and we do have mallards that stir it up quite a bit. Have never seen ag lime kill fish but copper sulfate will kill fry.

Also, make sure its POWDERED gypsum, not pelletized.


This. Gypsum is the safest coagulant to use as it will not alter the water chemistry other than increasing water hardness which is not an issue.

Alum (Aluminum sulfate) is the most effective turbidity coagulant but there is potential danger in dropping water pH to low (too acid) unless the pond water has sufficient alkalinity (buffering capacity).

It’s also important to note that there are different types “lime” - agricultural limestone (calcium carbonate), slaked lime (calcium hydroxide) & burnt lime or quick lime (calcium oxide). Slaked lime and burnt lime should rarely be used in fish pond management has they can increase water pH to levels that can kill fish. Agricultural limestone is the product of choice, but the least effective product for coagulating turbidity and “clearing” up ponds. Agricultural limestone has very low water solubility.
