I tried to do a search if and couldn't come up with anything. Has anyone who has a pond with tannin stained water had any luck with dying their pond with aquashade or do the tannins affect the color of the dye? My pond is 1/8 acre and 10 ft deep in a heavily wooded area with no weeds as the pond is 90% shaded through out the day. Water was clear after ice out until the spring rains came and filled it back up. I am not crazy about the brown color but don't want to end up with even worse color by adding a blue dye and having the tannins make it an even darker brown.

Pond dye is acidic I believe , often called acid blue or acid yellow. Tannic water is acidic also. If you have acidic water then it could effect water quality. Do you know your alkalinity or ph ?

I have not tested the water, I wasn't aware they affected ph, I will have to test it and maybe apply lime. Would that balance out the acidity if dye was added?

Sorry to jump in here... ewest, are you saying adding pond dye changes the ph? If so, is there an average of how much it changes?

Without actually testing the water, my gut feeling is that you'll never notice the change in pH. The amount of dye that goes in a pond is so insignificant compared to the whole volume of water in the pond that I doubt you'd see a change.

A little goes a LONG ways!!

Dye vol not enough to change ph measurably. But high acid content in tannic water may effect the way the dye works.
