Okay, I've read Rainman's threads here but I can be a little dense, so I figured I'd ask that 'stupid question'.

Here is a pic representative of the water my pond; it is roughly 0.4 surface acres, currently 10.5' max depth (7' average depth), with 1.5' or so until full pool/bottom of overflow.

I believe a big reason for the 'chocolate milk' is the drought we had right after the pond was dug last summer, making ground cover nearly impossible to establish, so when it rains the watershed picks up all the exposed dirt and clay on the ground and takes it into the water. After 3-4 days of no rain the water *slightly* clears...visibility is <6".

I put grass seed out around 3 weeks ago, and it is starting to grow in the warming, wet spring; I anticipate in another 3-4 weeks I'll have solid cover nearly all the way around the pond which will hopefully help minimize dirty water. I've also thought about doing some rip-rap around part of the eastern bank for erosion considerations.

As grass does its thing, I'd like to work toward getting the water cleared up some. I don't want gin clear but better color and visibility than muddy would be ideal. I've read about broadcasting alum and powdered lime (individually, in a water slurry), but suppose I need a little more clarity (pun intended) on this process. I'd like to apply from the shore if possible and I have a 1/2hp transfer pump that should throw pretty close to the middle of the pond.

Pond has 400 3-5" panfish and 10lb FHM in it, and there is a single 9" aerator disc about 24" off the bottom in 10.5' of water.

I should probably do the 'bucket tests' to confirm how much alum is needed, and get some sort of pH and/or alkaline test kit...but if my math is correct I've got roughly 3 acre-feet of water. Based on Rainman's original post, am I correct in thinking 200lb alum and 100lb lime would likely work for an initial treatment?

Property is in Clark County, IN so hopefully I wouldn't have TOO much trouble sourcing these from a farm store.

Greatly appreciate the advice and insight!
