yes, this tank is anemone safe, the wave box osscilates so it does not continuously draw water though the device, it simply pumps for about 0.5 seconds every 0.5 seconds.
There is a second pump (hidden behind the rocks on the left of the tank. To this is attached a SCWD which changes the flow of current (ie approx 500L pumped out in 2mins from the left of the and then 500L pumped out for 2mins from the right of the tank you can see the outlets emerging from the sand bed at either side of the tank.
There is a third pump in the sump, which directs flow from the top centre of the tank, towards the sides.
What all this achieves is:
1. Osscilating water (rocking action) which simulates waves passing on the surface; and
2 Mass waterflow (directed flow) which simulates current.
On the reef, nothing is ever still. This is what I have tried to achieve with this tank.
