That ATB rock cone ZEOvit reactor we spotted some time ago might not make it into production. ATB is stating that the “the movement of the rocks with a pump was not very good”. And with any ZEOvit system, the movement of the rocks is a must if you want to properly maintain a ZEOvit system. Still, ATB is known to produce high quality goods and even if we might be satisfied with the results that doesn’t mean that the perfectionists at ATB are. Hopefully, they will be able to work this out as quite a few hobbyists were excited about this new product, including us.
