Depending on what you're trying to keep your Calcium and Alkalinity are quite elevated. I would get your calcium closer to 420-450 and some coral (ie sps) tend to be easier to keep around 7-9dKh. In your scenario pH would not be the first thing I would be looking at. What salt are you using and what are you trying to keep?I am new to hobby. Struggling to understand and get correct. So frustrating. In the last six months I’ve read probably 500 articles/posts/blogs joined several groups on Facebook and watched hundreds of youtube videos on reefkeeping. Probably gonna sound really dumb to most people that are advanced in this hobby but I’m struggling. Idk what I’m doing wrong. My alk tested 12-12.5 I tested twice with brand new salifert kit good till 2024 (Hanna alk check on order thank god) ca 550 mg 1290 but can’t get my ph over 8.0. I did a 5 gal water change hoping that helps. I have a RSM 130d.
