I'll answer question #1 ,
fishless cycling , u will need , ur tank , ur filter running 24/7, the filter outlet needs to be disturbing the water surface , this creates oxygen , benificial bacteria (bb)
Need oxygen to grow .
U will need pebbles, decorations, plants etc ,
These create a surface area for the bb to grow on .
U might need a heater , keep water temp above 20c , bb grow faster in warm water , they can die if it gets too cold .
U will need a source of ammonia, usually dr timms ammonia chloride is used . Available from petco , , fish shops etc .
Directions on the bottle , and he has more advanced online info too .
U will need a test kit , the most recommended and widely used is the api freshwater master test kit , available petco etc .
I think thats all u need at this stage ... ?
Then its just a matter of waiting,
It can take up to 8 weeks .
With a fishless cycle u don't change water at all till cycle is complete .
Dueing cycling u will see an ammonia spike raise , then a few weeks later a nitrite spike , and finally u will see nitrate , the cycle is finnished , when u add ammonia to 2ppm , 24 hrs later the ammonia and nitrite will be zero .nitrates should be under 40 ppm
No lights are needed for cycling .
