Does this stuff really work? Our local grain elevator has a jug that had dye, suspend technology, and bio (good bacteria) all in one. Does this stuff really work, or am I better off buying everything separately? I have had runoff this past winter/spring which has given my pond a tea/coffee color. I was wondering if these blue dyes with suspend technology actually work with taking the suspended particles down to the bottom? The elevator did not have any alum either.

Thank you

I am always a little leery of "do all" cures. Like all season radials, sure they work all season, but if I'm in deep snow I want snow tires and if I'm drag or road racing, I want slicks.

Being a "tea" color, is almost always Tannin's from leaf litter. It is harmless, and can't be removed by alum, as it is not a solid.

Get some Alum in a McCormick's spice section and add some to a jar full of pond water and see what happens before spending your money....

Thank you very much for the info. I will start to research Tannin treatment. I know carbon is used to clear it, but our pond is too big for that. Will the water ever naturally clear? Right now it looks like a tea/coffee color. Is it a waste of money to even put dye in? We were at a pond seminar and the speaker told us if we put the dye in it would just mix and make an odd color then eventually go to the bottom quicker.

Tannins are normally permanent. In a fish tank the only way to take it out is water changes. It will take time and rain to remove.

Dye will change its look but will not get it out.

Thank you for the response Dono!

I did a little more research and that was kinda what I was thinking. There is a low spot of swampy woods by our pond and a lot of that water drained into the pond. We were able to eventually build a dike and keep the water from running in, but there is where the color came from. Maybe we will just add the black dye so it looks a little more appealing without turning a weird color.

Take some pics. We would like to see. Especially if you do use some dye.
