Welcome to the Forum! I would Google this and see what turns up. How do you know about the phosphate and how did it get there?
thanks dr dave im sorry in your reply was the last sentence a question or should i have googled it.
I was asking how you know you have phosphate in the water and if you have any idea how it got there. Some folks are on well water. We are not mind readers...:icon_smile:
sorry .I have water test kit that test phosphate ph 7.0 amonia0 nitrate0 phosphate 10+
I have 360 gal pond with pump with 6x4 prefilter into a waterfall filter thats 16x8 will have to build biofilter just not alot of room . oh ya i have city water maybe i should test that

Once you test the city water, we will have a baseline to work from.
just tested it less than .05

I don't think you have anything to worry about. Check out this site, it has info on this and has remedies for extreme conditions. I don't think yours is extreme.

BTW, I am not big on chemicals so this site, as far as I am concerned, is for information, not product.

I'm willing to bet that ponds always have phosphates. Plants and bacteria use them to grow. I am also willing to bet that using algeacide or having any decaying plant matter releases phophates back into the water column.
Not sure on ponds but this is the case in reef tanks. If you have a die off of high phosphate consuming life such as cyano then the phosphates will go through the roof in the water column even though the levels my not have been high enough to test before the die-off
