In short, I let my phosphates get quite high. About a month ago, I tested a level of 7.1. Over the past month, I have started dosing with NO3PO4-X. This morning, I tested my phosphates and found them at 1.8. My question is: what should I do now that I've reached a decent level? Should I reduce my dosage and find that low maintenance dosage? For reference, I like to feed a lot, so I'm considering aiming for the lower end of the acceptable range and then continuing to feed more.
