Bought a few SpectraPure carbon blocks, (part # CF-0.5-10) from a large reputable online aquarium supply, not from SpectraPure directly, and recived these carbon blocks. All the carbon blocks I received all say “Hydronix” and no where on the packaging for them does it say SpectrePure. Anyone know if these are genuine SpectraPure filters? I messaged the retailer and Spectrapure and neither were helpful. Thanks!
