I feel like I was experiencing, and to some degree still am experiencing much of what you have so eloquently expressed above. My primary reef tank is 150 gallons with an assortment of high-end equipment including: 4 radion lights, neptune dosing pump, trident (calc, alk, and mag monitoring), ato, etc.
LPS coral, for the most part have done ok over the past 2 years, with some mysteriously fading into oblivion and some merely existing. I have more time to spend with the tank due to this pandemic and have found that patience, coupled with basic equipment monitoring (hoses, lines, connections, salt creep, etc.) are leading to success. Just last night, after seeing a steady decline in my ALK levels despite dosing increases, I discovered my Neptune Dos had become unplugged (even though the light still comes on) and my line to the dual reactors were clogged. These are things that I just assumed worked and had neglected. I fixed them and am moving on.
Just 2 weeks ago my monti, a red digi, and a couple of other SPS took a turn for the worse. I watched parameters made some small adjustments and am seeing some veritable improvement in the montis and digi - even some of my long forgotten zoas/palys have started to resurface. Like you, I grabbed a couple more sps and watching nervously.
You have a nice setup and are seemingly knowledgable. Take your time and make sure those key parameters are where you want them to be before grabbing too many more coral. I don't know if you want to take the plunge, but it might be worth grabbing a trident if you can - I am finally enjoying my own.
Happy reefing and thank you for this post!!
Thank you so much for the kind words. It's always a happy and sad feeling to see others experiencing issues I am. All too often, the posts I see are of success and it just feels like it comes so easily to others and I just can't get it right, lol.
Ditto on the dose pumps. I ran clear lines using air tube so I can make sure there are no bubbles. What I didn't realize was the air line will harden at the DOS nipples over the course of a year and it was letting air draw in. I think that made my dosing either inaccurate or just pushed air around altogether, no dosing. Nonetheless, I cut the hardened ends off and bled the lines. All seems good now.
Good to hear some of your turned corals are coming back. It seems my experience has been, once they turn, mine tend to finish themselves off. I've had multiple zoa colonies that once multiplied to many. Then one day many of them closed up and shrunk into nothing. Feelsbad.
Thanks again for the reply. I hope you keep pressing on! I have to stumble on success eventually, right?! lol
