I accidently left my bag of DE out in the rain. Of course the bag started falling apart so I shoveled up the remaining DE and put it in a 5 gallon bucket. Now, since the DE is damp (sort of the consistancy of wet sand) it is soooo much easier to use. When I scoop it out, I no longer have the clouds/puffs of DE wafting in the air.
Of course I still premix it with water before I add it to the skimmer.
Other than the fact that my 1lb DE scoop probably holds far more damp DE than dry DE, are there any problems with this scenerio?
