Just wondering what's the difference between these two have always just used Whirlfloc just wondering what pros and cons are of each and if one is better than the other
I think both are carrageenan extracted from irish moss and/or similar seaweed and as far as I can tell the only difference is the tablet size and therefore dosage.
I've used all 3 and never really cared what they actually were other than knowing Irish Moss is a seaweed. The only bit that interested me was if they worked and as i still use whichever one is cheapest at the time of purchase I can confirm that they all seem to do the same job just as well as each other.
I used Irish Moss years ago before changing to Protofloc, which is Irish Moss but in a finely ground, pelletised form which offers a greater surface area/ solubility and therefore effectiveness.... apparently. I honestly can't remember if plain ol' Irish Moss was inferior or not but I've stuck to the Protofloc ever since.
