Ok I am relatively new too but here is what I can tell you... The 5000k bulbs have jsut about no benefitial contributions to the aquarium... I believe the 5000s are mainly FW
bulbs but you will probably never find a SW
hobbiest using them (that isn't new). CFs are a good start and probably adequate for a 55... I personally have 4x65w CFs in my 55g... 2 are 10000s and 2 are atnics. I think most people will recommend somewhere in the area of 4-6 Watts P/G... I think 55s and lower can do wiht a bit less probably because of how shallow our tanks are... I would stay around atleast 4wpg if possble. If your LR
was sent overnight you shouldn't have to do much curing since you probably had minimal die off. 2 weeks is more than sufficient IMO
. You do not "feed" LR
but you should keep your calc and ak levels at a stable rate. Some say all you need is consistent water changes to accomplish this but your best off getting a test kit. You may want to use some kind of suppliment or even pellet/flake food for any hitchhikers you recieved with yoru rock until you add enough fish to make waste food for the inverts. While you are pretty vague about what water parimeters you have I think you may be able to add a damsel or two (best to cycle with) in the next few weeks. Don't make the common mistake of buying expensive or pretty fish for your first one. The stress level will def hurt some of the more fragile guys. Damsels have been known to survive a nuclear winter. Get a few first and let them sit for a few weeks and watch the water levels. Once everything goes down to 0 you can start adding desired fish. You may or may not want to keep the damsels after the tank cycles. While some are descent looking... they can get very territorial. Keep your eye on them and if they start causing problems bring em back to the LFS
. Most will either take them as a donation or give ya a few bucks.
