Thank you for your compliments and words of encouragement. I was prepared to sell it but my wife said we should go with it. We have it for 5 years already.
Tank changed position to other side of the room.
We bought some equipment for start; RO, heater, flow pump, thermometer, salt, salinty tester and sand with bacteria.
Aquascaping ended badly, that's was the idea (see picture) but when I took it out and went downstairs to glue them together I tripped and dropped the rocks which broke into much smaller unusable pieces.
Hopefully today will be the day when we will fill it with water and I will start build thread and post link to it here.
