There are plenty of people who used this product without issues. There is clearly a lot of outrage about the false advertising on the bottle, but never fear, your tank is not doomed. I've dosed this product and never had issues. I dosed at half dose. I don't think I'll dose it again, unless I have a crazy algae outbreak and then I honestly might.So no way to remove this stuff from the system once it's in? Does that mean any live rock in the system is now garbage and shouldn't be used in new tanks?
What is the long term effect of this stuff? Do we even know?
