I might be experiencing the exact problem you have experienced.
Over the past 2-3 weeks I noticed my Ricordea mushrooms have been shrinking, and down right disappearing. Yes, I said disappearing all together.
My CA, MG, and dKh are all within specks for a ULM mixed reef tank.
I have to dose with Red Sea Reef Energy A & B because mu nutrients level are very low...0.25 phosphate, and 0.125 nitrates.
I have them placed on the bottom of my tank with not much flow, because that's the recommended location for them based on what i have read across multiple sites including Live Aquaria, World Wide Corals, and Ultimate corals, ETC.
I also dose with ATI Essentials PRO to ensure adequate amount of trace elements are available in the system.
Any help/suggestion for correcting this problem will be greatly appreciated.
Other softies are doing great.
