same here.
Well, almost good. So far I haven't suggested to anyone they should stop using Vibrant. But I think that changes without some assurance from UWC.
See, for hobbyists it would still be helpful to know definitively that the risks associated with Vibrant are
only those associated with the AlgaeFix active ingredient and not some other similar algicide that may be less tested, less safe, or simply have different risks / behavior.
We have no assurance on that,
@UWC.
All we have is a bunch of tests that say we seemingly can't tell the Vibrant and AlgaeFix apart by any chemical property, and also they are indistinguishable in concentration.
Put it this way, if you use AlgaeFix (as I sometimes do), then you have all the volumes of documentation of exactly what the risks are (RIP my long spine urchin).
Here's a link to a
60 page work paper from 2015 on the effectiveness of the ingredient in AlgaeFix on everything from trout to rabbits to tomatoes.
It's full of info like this... (hey look, it's good at killing diatoms), elsewhere the effects on crustaceans and mollusks are quantified.
If, however you use Vibrant, you only know that you are probably using a similarly potent chemical in a similar concentration but you have no idea if this level of safety check has ever been done on Vibrant. Because
@UWC hasn't or can't give that assurance (because possibly it hasn't been tested except on their systems and then the hobby).
So if you use Vibrant, you're actually just HOPING it's actually the AlgaeFix ingredient at a similar concentration. That's really the best-case scenario at this point.
