I am back again here with another alias...
The RedSea 900 is officially closed down and sold to the new owners.
It had some bubbles developing in the seams so RedSea sent me a new display tank but I decided to sell it and go even bigger with a brand new tank from akwarium Szczecin Poland...250x80x70 (1400L) with a dream dreambox sump from Royal exclusiv 175x60x35 (350L) so around 1700L in total water volume.
This tread is officially closed.
Happy reefing,
Farham.
