Hi -
My system is in definite need of minerals. In researching I keep coming up with a product called Eco Rose and unfortunately it can't be sold in Canada. Does anyone know of a good substitute? I live in a small community with not alot of stores and the closest thing anyone could find was something called "fritted trace elements" however the staff were not grasping how aquaponics works and no one could tell me if this would be safe to use.
