Hi everyone, I have recently purchased an eclipse 3 gallon tank the one that comes with the filter, pump and standard lighting, (there are pics on my profile) I have 4 pounds of argonite on the bottom, and 3 pounds of live rock, I've premixed snd added my salt and added the proper amount of stresscoat. I've alos added a submersible heater so the tank is staying right at 82 degrees. I'm starting to see a bit od pink growth and some little corals popping out from my rock. Here's my question....What is the easiest way to keep my live rock growing, I'm not interested in adding any fish for a long while, I just want to see what my rock produces...do I need to feed it? and do I need different light? and with a tank this small do I need a skimmer? Thanks so much!!! in advance
