Hopefully you can see how much they have both grown already, it would be more obvious how much the little Motoro had grown if the Pearl had not grown too.
I have also added a pic of my Freshwater reservoir used for the auto water change - when the sump begins to pump out (timed) the top up turns on a dosing pump (Deltec auto top up) and dechlorinates the water, a pump refils the sump and circulates the fresh water with the dechlor.
It seems to work a treat apart from sometimes in the middle of the night it tops up a tiny amount due to evaporation from the sump so I need to either have it auto shut off at night or reduce the evap losses.
NOTE: in the first pic you can see the Pearl running along the width of the tank, this is just under 36inches wide (front to back)
