Phosphate spike

[11f150]

I have been dosing nitrate and phosphates for a few weeks now. I decided to keep them at 7ppm and .07 ppm. They have been very stable but I tested today and my nitrates were 7.3ppm and my phosphates are .14ppm. Any idea what would cause this? I guess I could have overdosed but I normally am spot on. I am just confused and wondering if something else could have caused it. Second, could this cause any issues? Should I just let it fall naturally?

Thanks

These differences could just be normal variation in the method. In other words, these changes seem to be too small to mean anything.

Gotcha. I will keep testing and keep an eye on it. Thanks for the response.

Just updating. I haven’t dosed nitrates or phos since I created this post. Been feeding a small amount of frozen food, probably half a cube. My phos are now .25 which is concerning to me. Nitrates are 7.3. I also have a ATS running now which has been going for maybe 3 weeks but that is the only change recently. Should I do a few water changes? Seems something is putting phos out now
