I started a new tank setup a few months ago and being relatively new to the hobby I am now realizing that in order to cut down on the initial cost, I did some things wrong. One of these things is that I didn't get enough substrate in the tank for me to be able to keep a well planted tank. I have a 32g that's 36" wide and got 22lb of GEO system gravel substrate in there. While it covers the back of the tank nicely (anoput 1.5" deep), it is not enough for the front of the tank if I want to add some foregroung plants.
Question: has anyone ever added substrate to a "live tank"? If so, how should I go about doing that? I was thinking that if I get the same kind of substrate, and wash it thouroughly and only add it is small doses (say 2 lb / day for a few weeks) that it would get me to the level I would like to have, without clouding my water over too much. However, I am uncertain how the fish would take it... or if it's bad to add substrate on top of an already cycled layer?
Thanks for any anwers. :)
