I have a question about a Mr.saltwatertank (Mark Callahan). I fallow him on youtube despite the fact I don't have a saltwater tank (learn now not when I get it). But his info sounds good, his tank(s) look great but, the like dislike bar shows about half dislike on all of his videos why is his info wrong?
