Hello everyone. I am new to the saltwater world. I bought a 55 gallon tank and dry rock. I set it up this past weekend. I used 40 pounds of CaribSea live sand and Instant Ocean salt. Im running a sunsun canister filter and about to buy a coralife super skimmer (not sure if its good but has good reviews)... My mind is in a million different directions on this cycling process. Everywhere i look everyone has different opinions on what to do. So im probably about to ask some stupid questions. \n\nWater change:\nsome people say 50% weekly some people say 20% week and some say dont do any water change. so what is the correct procedure here? If no water change then do i do a water change before i add fish? after tank is established i was reading 15% water change monthly?\n\nLighting:\nIm not that it really matters to much but i know some people say no lights on and some even say cover the tank.\n\nAfter the cycling process i add some sails and hermit crabs and shrimp to clean the tank from the cycle (im assuming the tank will be pretty nasty?) how long after i add the CUC can i add fish and does it matter if i fish or coral first? Sorry to a bunch of dumb questions i just want to make sure i do it right and not someone shortcut way. I mean fill the tank up with water and wait 4-6 weeks for everything to read zero sounds to easy. Thanks in advance. Im sure ill have some more questions after the cycle lol.
