Have anyone try out their pro series line before? I came across this food at my Petsmart, the ingredients is similar to Fluval bug bites which also include black soldier fly lavae as their first ingredient.
There is a thread on this like 5 below your question, may want to use the search functio prior to posting a new question. Like mentioned by RD I personally wouldn’t use anything made by Top Fin even if it was free...
Recently got this because to my eye the ingredient list is pretty good. All of my fish also seem to go crazy over it and I dig that it has multiple granule sizes.
