i just use the compact lighting system that came with the setup. Zoas and yumas dont need strong lighting so it works perfect. Just lots of live rock and a huge sand bed seems to work great for them. I also kept everything stock, no mods of any kind. Put a koraliia nano and a nano protien skimmer that has worked well. Key for me is to clean the sponges change the carbon monthly and change out the air stone for the skimmer monthly. All the level have been perfect. I also have a panda goby, yellow watchman goby, sharknose goby, and a royal blenny and a pink firefish in the tank, so its pretty stocked. also do a 5 gallon water change every week, probley the most important thing. I have not lost a think since i have built this one. It is for sure harder then bigger tanks ive built. Always something to do to it everyday, so cant be a lazy fish person with these. Mine is over stocked too, to be honest, but it works for me, im about to have to frag all the zoas, i have alot of them fragged all over the tank, but room has become limited. I love it though lots of color
