I saw a guy on here albano selling some from his fuge to fit skimmer in so if you need some at a fraction of what places want buy his.It is truly alive see his tanks know it is pest free and healthy for yor tank.I got some and was amaxed at the diversity he has growing
thanks i just read it but i wanted to know more about it but decided not to go with it since the company "eccosystem" said to replace half every 12 months,
