My 10 gallon nanotank has been struggling with high phosphate (Hanna checker: 0.32-0.90ppm) And I have been using elimiphos rapid over the past few months. I started with 1ml per day and gradually increased to 6ml per day (I have added 6ml every day for a week I know it’s a lot). However, with...

I am dosing for the first time for alkalinity and started at 7.9 but went to 9.5 which is well over the recommended 1.4 daily increase. Will this damage the reef? If so, do I need to do a water change to correct or will it be okay, just don’t dose anymore ?
