Does anyone know of any affordable alternatives for refugium mud? I need a decent amount for a project I have in mind but I really don't look forward to spending $100-150 for just 4-5 gallons of mud which is really just dirt to me. Anyways, if anybody knows of anything safe to use that is used in other areas of life, i.e. special plant soil or such (just like play sand used to be used in reefs) Please let me know here so everyone else can save themselves some cash too lol
