I have done a lot of reading and research and purchased a 29 gal. starter kit from my LFS. The kit contained the tank, salt, heater, test kit, hydrometer, lights, and a Bio-wheel filter. I have since purchased a koralia nano and plan on getting another one soon. I plan on having a FOWLR with live sand for substrate and about 35 lbs of live rock and no sump due to budget. Is there anything else i should add on to this setup? I am on a budget and any purchase over about $75 may take a while for me to get.
