Ok so for months I was fighting a losing battle. Never figured out why my corals were slowly dying after 6 years. Now my rock has this stringy thick algae which im thinking now is dinos or maybe some form of Cyano
. It started growing on my corals except for my 27 head torch coral which I have moved to a QT tank for holding. So I'm taking the rock out and discarding it. Honestly I never liked real Reef rock. Just was too dense so I'm not tooo mad. I was wondering do you guys think I need to change the sand bed. I have ALOT of life in my sand and keep it rather clean with every water change. Should i just take the rock out and give the sand a good siphoning then water change or just get rid of everything. I really love this Tropic Eden Reef Flakes. Any Advice?
