I am currently testing Calanus, Pure food and life source in my system since last one month or so. Calanus is more of a fish food and fishes just love it (tang, anthias, clown and wrasse). I can not certainly say anything about the pure food as I don't use it daily but nothing bad happened to my corals so its fine. Possibly it will take longer to comment. Now, coming back to most debatable product of this line, life source. In simple language its mud. Possibly collected from some low tide area but it smells exactly like something directly from sea. Now, AF recommend this for sandbed or refugium but I dont have any of it. My system is bare bottom and without refugium. So, I was little skeptical about using it first time.But I like more natural thing and after opening the container and smelling I was ready to give it a try. Took some tank water mixed it and dumped it in the tank. The whole tank became cloudy and I was waiting finger crossed. After an hour everything cleared up and nothing changed. So, its been recommended to use it at least once a week and I am using it twice but half recommended dose. I have not seen any change in parameters or skimmer overflow. But I observed majorly two things. First, when I dose and the tank is cloudy my corals goes to feeding mode like they are getting food from the water column and second after a month of use my whole system is getting a high rate of purple coralline deposition. I don't know the reason behind the coralline but it can be more mineral and biodiversity balance caused by the product. I wish to do a full ICP testing after 3 month of the product usage to figure out how the system is responding to the new product.
