Thanks Down_Shift, anyways probably thinking of replacing the java fern with something a little smaller. And what I mean by that is something with smaller leaves (that doesn't make my tank look tiny) that gets really bushy, so it will hide my future pump. I was thinking somethin' like a anubias nana or a cool-looking crypt.
Yesterday I left the light on for a very long time because I had just added the Co2 tablet, and I wanted it to go to use. And would you believe it, my fern and micro sword were pearling like crazy! I was really worried about the micro sword, because it went through the process of being submersed for the first time yesterday. But don't worry, I will spread it out.
When I get the HC, I think just 1 pot will already give my tank a full carpet. Because the tank is so small, that I don't think there is too much substrate area to cover. HC here can range anywhere from R$ 5-15,00. But it's fairly easy to find in stores.
