Of course not nothing is 100%. For example - in the study that was done with the pictures showing the corals exposed to different antibiotics before and after, etc - they only used one specific coral. Does that mean they would get the same results if they used a different type of SPS? I dont know.I’ve seen his before and after videos, but they aren’t very well done IMO. You would need better quality video over several days or weeks to be sure it’s working 100%.
We’re testing ampicillin too.
Just curious...do you believe every study you read with 100% certainty?
That said there is more than one study on this topic - and if you look at the introduction in the studies that start back in the 2000's they reference prior studies - the studies done in 2011 reference the 2000's studies, the 2014 study references the 2011 studies, etc. So there is a basis / history of science that tends to back up each new study - and allow each new study to try to correct potential problems with the ones before it. In each of the studies there is usually a mini-review of why their results are valid (or more valid - or confirm prior research - or disagree with prior research).
In this case - and in your posts I dont see any of this type of thinking. You started out with 'we have the pathogen' - when even the article you posted in the OP says that there is no evidence showing that the several types of ciliates containing zooxanthellae (not just Philaster) were causal in RTN type disease. there have been at least 2 other articles posted clearly analyzing and stating that bacterial infection is the likely starting point for RTN - with ciliates coming later. There is a well written paper that shows that ampicillin and another antibiotic halt RTN - while treating with metronidazole to the point where Philaster is 'undetectable' did NOT stop RTN.
So - It surprises me somewhat that you seem to ignore these other things in favor of a product whose ingredients we dont know, that may be reef safe (with no fish - or not) - we dont know success/failure rates - we dont know if there are long-term negatives etc. BTW - Im not slamming the product - this is the reason I try to use as few of these 'cures' as possible in general
