I've switched over to tapatalk a month or so ago and haven't been getting notifications for my threads on here. Anyhow. Not much new to report. Still mostly a lost cause on this tank. There are 2-3 acropora that seem to do ok. Not much growth, but so-so color and PE and I keep going through a cycle of brief growth, followed by STN, trim, remount, grow, stn, trim re-mount, ect...
I have stopped spending any money on acropora. I haven't purchased or added any new ones in several months nor do I plan to. I still suspect either a pest or some sort of non-testable contaminant that will likely either plague the tank forever, or until they're all gone and I go fallow for several months. I have offered all of my acropora to locals in trade but nobody has anything good.
It's a bummer and has caused me to lose significant interest in the tank and hobby in general. I sold my metal halides and went with some leds since I was unable to really take adavantage of the metal halides for their acropora growth. Montipora and zoas seem to be fairly indifferent. Oh well. Once day several years down the road when we move I'll likely sell off the entire tank and start totally fresh and new with mostly new equipment and all and give it another try. I've kind of been focusing on other hobbies due to acro troubles. Even turned off my dosers and stopped testing/water changes.
