This thread isn't taking new posts but I see this
critical warning isn't listed.
ONLY use food grade (ORGANIC) DE!
DE can also be used in a chemically processed form which changes it's chemical composition (this is mainly & widely used in pool filtration system)
THIS DE WILL KILL YOU, YOUR, DOG ETC ETC.
NEVER USE POOL FILTER INDUSTRIAL DE.
