Multiple Applications for Complete Parasite Eradication: It may be necessary to apply the treatment on two separate occasions for complete elimination of parasites.There is limited information available regarding the effectiveness of Subquaria in eradicating eggs from mature female parasites. It is possible that these eggs may be expelled post-death and continue to pose a threat to the viability of future worm infestations. ATTENTION - Kindly Review It has come to my attention that numerous clients have communicated instances of ineffectiveness in controlling parasites when utilizing Levamisole Powder procured from alternative sources. This is likely due to the presence of adulterants or the use of expired product. I would like to emphasize that our Levamisole Powder is of exceptional quality, as it is 99.9% pure and free of any cutting agents, apart from minimal traces of naturally occurring airborne dust. Please strictly adhere to the recommended usage guidelines to ensure the well-being of your aquatic life.I must caution that I shall not be held liable for any adverse effects that may result from deviating from the provided instructions.Regards,Subquaria Subquaria's Levamisole HCl Powder - YouTube Video will open in a new window [isdntekvideo]
