In otherwards the ones that are labeled for aquatic use had their manfacturers do the expensive testing.
Yep, AND they passed the testing process. We'll probably never know how many tests were failed first.
Probably none but the cost was the same.
BTW Scott what's the deal with Aquashade and the other pond shade dyes? Aquashade is approved but the others aren't, but the others still sell their product?
