Water volume is +- 120L with an xtra 70L in the sump.
Two pipes - the overflow pipe, as well as the airlift that drives the UG filter, are hidden by 2 columns of rock.
Skimmer and DSB in the sump.
The overflow pipe consists of two pieces that are joined in such a way that water can slowly seep through the joint,
but at a slower pace than the inflow from the return pump.
This allows me to simulate low and high tide by simply switching the return pump on or off.
During "low tide" I also switch off the powerhead inside the main tank to create calm water - like an isolated tide pool.
The airlift still continues to push water that percolates down over the exposed rocks.
The anemones in my tank react completely different depending on what tide it is - they become elongated during low and retract during high.
Some snails and hermits love to sit on the exposed rocks during low tide.
Everything seems to come alive once high-tide arrives.
a Bonus is that I can save a little bit of electricity by not running everything all the time.
I can also keep the temp down when needed - today I measured 35degrees C right next to the tank, water temp was only 24degrees.
I've been running hightide this evening and temp has gone up a degree, so time for low again...
One day I will syncronize everything to actual tide charts.
