My tank was 75gal, and used zeovit system for 3 months. Fortunately, the PO4 in my tank now is mainly at 0.03~0.04ppm (tested by Hanna). At 6/17, I started to drop Spur2 in my tank. This is my first time to drop Spur2 and I used 75% of commented quantity. After 48 hours, most of my corals were OK, the color did not fade out, however. Only a small sps looks not health, those hydras did not come out almost 3 days. Is it normal?? How can I avoid such situation when I using Spur2? Thanks!
我魚缸是75加侖(約300L), 用Zeovit 3個月了, 目前PO4維持在0.03-0.04. 6/17第一次用建議量的75%加Spur2. 48小時後. 大部分的珊瑚情況正常,也沒什麼退色是真的. 但是有一顆小的SPS卻顯的不是很健康. 水螅體已經3天不出來了. 這是正常的嗎? 再加Spur2時應如何避免?
