So I have a 10g nano tank that has been doing great until recently. I have a small mushroom garden in it that is thriving and a medium green kenya tree that is doing great. The only problem I am having is that my frogspawn will not open. I just tested my calcium and alk and they are high. Calcium is at 500ppm and alk is at 10.2. How do i lower them both? Also is this why the frogspawn wont open?
