I would not be able to state that quote bad water quality like he had will not harm Aiptasia. I do not know that he had bad water quality. All I know is what was presented. Air bubbles, higher than normal alkalinity and salinity, and Aiptasia disappearing. I do not know anything other than that. I may infer, due to the statement about not getting around to fix the pump for a month as he has a busy life with a newborn and football, etc., that maybe there is some neglect to the tank. Although, that would be somewhat of an irresponsible assumption on my part. Stating that things, especially unknown things, did or did not have any effect with absolute certainty is not something I can do. I can draw conclusions based on information provided and state things that may or may not have any effect. Again, I’m not disputing your claim. I am stating that other things may or may not have had an effect in the op. My concern is for the health of other occupants of the tank with rising alkalinity that could possibly continue without intervention. Again, for all I know the tank has been tested and is perfectly fine. Maybe it’s just faulty test kits or results. I do not know. I do know about life getting in the way of things. I also know that I have regretted not performing simple tasks that only would have taken a few minutes of my time that unfortunately, created much more work and headache later on. I am not stating that is what’s happening in this case, just providing a little nudge to check a few things that for all I know, have already been done. Your experience is completely your experience. Share it with the world, have a couple repeated experiments in different tanks and have it repeated by peers and then I can accept it as fact. Until then, I just can’t, it’s not how I work. I think performing your experiment in a system without any Aiptasia predators, the file fish you mentioned, would be beneficial to your experiment. I’m not stating that your file fish did all the work, just that it may cast a bit of doubt as to micro bubbles being the absolute sole cause of Aiptasia eradication as far as experiments go.
