We have over 10 years a waterbed and now tried different conditioners ... this one of Blue Magic is indeed cheap, but primarily has the great disadvantage that it leads to a lot of foam and thus air formation in bed. It's annoying and you can just bad remedy because it primarily is a sparkling with the breather pump. It has been thus with fleece cushioned mattresses eventually getting air in the bed with us or even on one side a spongy couch feeling because the wave calming mat in the mattress foam was full. We are also in spite of every 12 months even pour the water tipped over, which has led to considerable odor nuisance. So we had to pour expensive sanitizer. In the conditioners of Stricker chemistry ("Clean Water") had or we have these problems now no longer, because the well has integrated air and tie on top of that, according to our waterbed local dealer also a much higher drug combination. I agree prefer a little more and have peace in bed and guaranteed 12 months freedom from bacteria.
