Changing from gravel to sand, advice needed!
I really want to change from gravel to sand but am confused about how to go about it. Do i take my fish out? I dont have a spare tank so dont really have anywhere to put them. When (if) i put new sand in can i put new plants in too? I realise this isnt an ideal thing to be doing with the fish but if it is going to put them in serious danger i wont do it.
My gravel isnt that old but looks really dirty and i have the odd bright green stone which i assume is algae...if i cant change to sand, is it spossible to give the gravel a good wash!!!
Thanks for your help!
