as I had a problem with the cracked tank a year ago it left me with severe trauma (my tank are now on the first floor). so this year after having negotiation with my parents (the fishes are in their house, I live in a 50m2 flat - no place for 20 tanks
) I got a ground level room of approx 16 m2. but this room is no suitable for aquariums as it is so... I will break my self of work. here I will write all the news and progression.
wish me luck!
