TBH, it works excellent for the aptasia and majano AND blue cloves which you can see and reach. I stopped using it because I want to kill off the ones living inside holes and places I can't reach with the wand, so I bought 2 pepermint shrimps.
with the pepermints I no longer need the wand but they are the reason why my tank is SPS dominant right now, (only have a few acan colonies left).
