I'm busy setting up my tank. At the moment I have decided on a DSB for my sump. Will be approx 25cm long x 30cm wide x 17cm deep.
My question is: Should I have a DSB (10cm) in my display tank (120cm(l)x45cm(w)x55cm(h) as well? Or should I stick to 2cm playsand as substrate?
I'd appreciate some good advice. Thanks.
