I am new to saltwater. I recently purchased a Fluval Flex 32.5 gallon tank. My LFS sold me Seachem Marine Buffer and Seachem Prime. When I read over the owners manual of my tank they are recommending me dosing the filter in Fluval Biological enhancer after every media change. My question is, is this the same as Marine buffer (aside from brand names) or are they two totally different products and I should purchase the biological enahncer as well?
