WHat is it? and how can I avoid getting that white salt looking crust on the lid of my aquarium?

Thanks
 
Most hardness test kits have both kh ang gh together.. Personally I like keeping an eye on the KH and maintaining it as if that is right your PH should be nice and stable...

I asked if the GH was high simply as it can cause the problem described, not a huge issue though, just clean it as others said (GH is very low in tap water here, but I guess that can be very different elsewhere)..
