I'm thinking of converting my gravel substrate in my 29g to sand.
Given that the tank is established now, I'm wondering how to go about this.
The easiest thing I can think of would be to add a 1/2" layer of sand on top of the existing gravel. Would I be able to do this without removing the fish? The idea would be to do this in stages - perhaps do one corner of the tank & leave it to settle for a couple of days & progress round the tank that way.
Any ideas where I can get proper aquarium sand? I've seen some places selling coral sand for marine tanks - is this suitable for freshwater too?
Any help gratefully welcomed!!
