A bit more info. I did indeed post to Seachem's web site, and they called me up to apologize! They mentioned that some of the 'older' bottles (I'd bought mine online) were mislabeled. I was impressed that they followed up. In fact, they're sending me a 'plant pack' in apology for the problems their product caused. My faith in humanity actually went up a couple notches when they called me. I definitely didn't expect that. I've long held the tropical fish industry in pretty low regard and, in fact, rarely use any chemical products regularly other than dechlorinator (I didn't use that in the past, either, when I had well water) and polyfilter when packing fish. WhetherI actually use the product, however, remains to be seen. Right now, the fish are much happier after a couple 90% + water changes. Algae, with those rockin' ancistrus, has ceased to be a problem (that plus reducing the photo period and increasing the plant volume.) Still, I'm impressed with Seachem. Very professional and are trying the best they can to undo the damage. Plus now I have more room for fish from the Aquarium Event of the Year coming up on 4/14, the GSAS auction!
