I’m still learning and was wondering about pH levels. I Was doing my weekly water change and everything in my 10 gallon nano reef tank is going well. All my fish, corals, and inverts are healthy. All my levels are normal (ammonia 0 / nitrite 0 / nitrate 10/ Phosphate 0.1 / Ca 440 / dKh 9 (161 ppm KH) except my pH is showing 8.8. Is is something to be worried about or try to adjust down closer to 8.2? Or since the tank is functioning fine let it ride? Thanks
