Hi uwiik
I just saw where you are located and what you are actually doing for a living. If you could install a trickle system in your facility, you may have a huge advantage over your competitors. Last week I talked to an importer here in Germany and he told me that basically all live rock that he receives contains aiptasias. Apparently the holding systems at the exporters are so massively infested with them that they colonize every rock that enters their system. The general quality of the rocks did not change, but the number of unwanted guests is increasing dramatically. A trickle system could help a lot.
Please keep us posted
