After having my 90 gallon setup with a DSB. I really wished I had done the same to my 20 gallon setup. It is currently setup with about 1-1/2" to 2" of crushed coral. I want to add sand to it. Either replace crushed coral or just add sand on top of the crushed coral? What do you guys think?
Plus, should I add "live sand" or dry sand?
Please help. All input appreciated.
