The time to get the most consistent test is winter when little plants, algae or phytoplankton is growing. When water tests are done, the water should be as consistent from test to test as possible, i.e. same plant/algae growth, etc.
How to reduce P is a book. I don't think there is ONE magic way, a multi pronged approach is required. Many plants growing and utilizing it. Both floating islands, and submerged plants. You can lock it up with Phosloc or aluminum sulfate. Tilapia dying every Fall and being removed from the pond. etc.
There are low P foods out there too..... I saw a reduction in algae growth in my pond when I switched foods. BUT, I didn't have a baseline water test done prior, so I have ho idea if there is less P. My gut says yes.
Thank you sir!
that's what I thought, several ways to reduce but not a sure thing, esp when the Tp will be taking a dirt nap soon. Where are all those DAM fish eating birds when I need them lol
