I have reef tank with 5 tangs, opened tank about 5 months already. I always change 20% water every 2 weeks, and usually pH is around 8.0 - 8.1. Today, I leave home today noon, ph is 7.9, then I added one tea sppon of pH buffer in cup of water and pout into tank. (I alway do this). when I come back at night, pH is 7.3 !!!! I have chiller and only I only added a small piece of "Sun Flower" yesterday. Why that happened? What should I do now?? I seems all livinf things are still surviving. PLEASE HELP !!!
