I have found an increased formation of air bubbles in my waterbed and then bought to counteract the. I've assumed that the product Bubble Sorb sufficient for my two water cores - unfortunately a bottle of Bubble Sorb is "only" designed for a water core. So you need two bottles of water 2 cores - which is just not in the offer description. I have just 400g divided and filled in every water core each 200g. The effect was amazing, when filling a change was noticeable. I have again vented properly before filling, both water cores and still came up short again after filling air out. Since then, peace.
The "test tube" with the product Optiwet I have not yet used, can therefore say to little. The concentration certainly seems to be very high, because this little test tube full should be enough for 300L water. Not much more I can, unfortunately, not say - in a few weeks I look again at the development and then decide whether I use it in addition to or simply lift up first.
