Going to be doing some frag swaps this spring and been preparing most of winter, Ive got almost 100 frags now. I also purchased a 24X18X12 tank for the swap. My questions are besides lighting, and heater what else should I bring to be successful at the swap? Do I need powerhead, or will this agitate the water too much and obstruct viewing? Any other tips will be great since this is the first time I am going to be setting up tanks at the swaps.
