I have been testing my phosphate levels in my tank for the last few months with a Hanna Checker and it always reads about .72 -.78 Some other water has been tested to make sure the checker is working and its getting .05 in that tank.
My issue it I do not have alot of algae, my corals are growing like mad and have great color.
I did have some bubble algae but it has decreased down to a few small patches.
Can the Hanna checker be reading something else in the water?
