LRS LRS Premium seaweed is tested and free from over 400 possible contaminants and 22 radioactive isotopes.

LRS seaweed was trusted in the yellow tang captive breeding project due to the lab test results verifying the purity and quality of the sheet seaweed.

"We have been using LRS sheet seaweed with our Yellow Tang broodstock for about eight months now. We prefer this product over the grocery store variety due to Larry's extensive quality control screening of the seaweed."

Using our vast network of resources, we found an importer of seaweed harvested from waters tested to be free from pollutants, heavy metals, and radiation. In addition, Porphyra yezoensis is one of the most nutrient-rich seaweeds you can feed your herbivores.

Sure, many folks feed seaweed purchased from the local Asian market, as it is very cost effective. However, due to many environmental variables, there is a BIG difference in the quality and purity of sheet seaweed in the marketplace.

Seaweed, or "Nori," is graded, packaged, and sold based on the grade it is given regarding palatability, texture, appearance, and imperfections. If you hold a package of LRS seaweed next to any other brand, you can clearly see the difference in vibrance and texture. Your fish can definitely taste the difference, which is why this product has a very strong following with very little advertising!

LRS Premium Seaweed is packaged in a heat sealed, UDSA food grade poly bag which contains one ounce (30 gram) or approximately 22 sheets, which measure 4 x 7.5 inches.
