1) You can use bleach also. Take a cap or two in a bucket of water and wash the tank out really good and then rinse very good. Let air dry to make sure all traces of bleach are gone. I`ve done it many a tank whether mine or setting up someone else`s tank.
2) Depending on whether the LR
is cured or not. You can even get base rock (dry) and cure the rock and cycle the tank at the same time. What ever you do dont use fish to cycle the tank. We have an excellent article on cycling in our SW
BTW welcome to our site.
and a skimmer are really all that`s needed. If you want more then a sump or refugium can be used. I do have a refugium on mine.
4) What type lighting really depends what type corals you want. I have soft, LPS
and moderate light SPS
corals. I use a VHO
retro fit kit. I also dont run a canopy and use a reflector dome on top to make sure all light makes it in the tank. If you want anenomes, High light clams or high light SPS
corals then you`ll need MH
`s or T5HO system. You can check out my system by clicking on my signature where it says "view my tank."
