Hey, so yesterday I got some good advice on here regarding clown fish kept dying and seemingly suffocating within a day of getting them. I restarted my rank. I got my hands on some RO water from my LFS instead of tap. I did a 95% water change and wiped down the entire tank, turned over the sand, cleaned the filter, power heads, etc. I switched from Instant Ocean Reef Cyrstals to Red Sea. I also bought a piece of cycled live rock from that LFS and put it in my tank with my old rock. It's small but it's something. I turned one of my power heads to face the surface of the water to add more surface agitation. Added Bio Spira and the salt is mixing. Tank is empty. I have Dr. Tim's One and only coming tomorrow. My question is, to speed up the cycle, can I add the Dr. Tim's tomorrow or would be pointless? My LFS said don't and leave it on the shelf until I really need it since it's a bit pricey. She also said with the biospira, cycled rock and live sand, despite the crash and huge water change, the tank should be ready for a hardy fish in about 2 weeks. I really don't want another crash. Thoughts?
