Aquascaping an existing tank.
I have had a tank for about 4 months, so I am pretty new to the hobby. I did my research and carefully selected everything I wanted but now after 4 months I realise that I really knew nothing and that I want to make some changes to my tank.
I would like to know how I can re-scape my tank?
I started it with some dried out live rock and seeded it with some nice cured live rocks from the fish store. If I take some out and leave it to dry so that I can make a big rock structure using some putty will this cause an ammonia spike when I out it back in if thing have died off or would the bacteria in my system cope? Also, if I used some new dried rocks from the fish store would this be ok to add?
I now have some better ideas of what I want but I don't know how best to go about it given that I have a tank with live animals in it.
