Do you get good algal blooms ... just saying ... that if there isn't enough algae ...

My artistic touch on that graph is misleading, I am sorry...My pH actually spends time above and below neutral, but only slightly either direction. My intention for the chart was to merely show the peak later in the day. I believe my ph to be in good place.

I may be short on algae, however, since the brown color of the water subsided, after the removal of some craws, it has had a nice green color. And, the pond has had a few heavy blooms, typically early in the summer. So, I feel like the algae is there...but may be struggling with consistency. What I have very little of is submerged plant-life. Here are a couple examples of heavy green blooms...

Here is one before the craws were removed with the muddy waters that existed most of the year (secchi = 12")...

Here is a recent photo that shows the lack of muddy water with it's touch of green (secchi = 22")...

A PH modifier (like lime) might be front and center on any recommendations made.

I might be low on algae and have too much fish biomass also...pushing my ponds carrying capacity. Wouldn't the ammonia tests show that?
