'Morin,
I've been using TM Pro for almost 2 years now (in my 2-1/2 year old tank) and have been happy with the salt. One of the things I most appreciated about the salt is that it leaves no residue in my 32g tub that I use for my water changes. There is a Tunze pump sitting in the tub that constantly circulates the water. Typically, I'll mix up new salt water about every 2 weeks or so.
I've noticed that my last 2 TM Pro purchases are leaving a white "powder" residue in the tub. I last cleaned the tub about 2 months ago and the white residue does seem to be accumulating with each new batch of new salt water. The white residue does not dissolve and will float in the water column when disturbed and then settle back down to the bottom over time. My LFS suggests that it is excess magnesium and that all is OK. The only difference that I can think of is that the last few purchases have been with the large, 50 pounds?, bags rather than the slightly lighter buckets.
Not certain whether my issue is unique or whether someone has some ideas about what might be happening - but I thought I would share my experience.
Happy to hear anyone's thoughts.
Joe
