Question about live rock........

Personally,I wouldnt run the lights at all untill the rock cured and the cycle was complete.That way you shouldnt end with a bunch of green water to start with.
Too,Some folks have both the whites and actinics come on at the same time,some have the actinics come on first.I like for the actinics to come on first and run for 3 or 4 hours before the whites,then the whites go off a couple of hours before the actinics.
 
I hope I can tag onto the question and reply with a follow-up question?

I am setting up a 120 gal tank as well. If I follow the 90-100 base and 20-30 Live rule how long before it all becomes real? What do I want to add or not add to prevent the base rock from becoming live rock durring the process?
 
with the lights he has it will be about only 3watts per gallon. He would not be able to successfully keep much more than softies right?


refering to this question.......with the light system that i have what will i be able to keep in the tank? Also how many watts do i want or should have per gallon to have like anemone's, LPS, SPS, etc........? (just a reminder about my light system....i have 2 blue actinic 96w and 2 10k's 96w)......should i have more or is this enough?
 
You would need to replace the fixture altogether if you want to keep SPS corals,anemones and clams.Metal halides or T5-HO/T5-VHO with individual reflectors is what you would need.I don't really quote ''watts per gallon'' because its way more complicated then that.You can add more watts and it will help you keep more LPS corals but it wouldn't help SPS corals.PC's are nowhere intense enough for those corals.

Your fixture now is good enough for soft corals and maybe some LPS corals if kept in the top half of the tank.
 
ok.......so if anyone can or wants to answer this for me. basically what can i keep with the lights i have now......because ill have to save up money for lil bit to probaly get the lights yall are talking about. so any info would help to let me know what i can get.....thanks
 
The watts per gallon thing is more or less an initial guideline to go by or a somewhat "rule of thumb". Like others have stated currently you could keep some low light animals such as some mushrooms, christmas tree coral. You might be able to keep some candy cane coral, frogspawn or hammer if they are kept higher up in the tank. Some people will tell you different things. I kept LPS in my 75gal for about 14 months under 260 watts of PC lights and they thrived and thats about 3.5watts per gallon or so. I know have a total of 692watts of MH and PC over my 75gal which is over 9watts per gallon. So you might be able to get away with some LPS corals with the lights you have.
 
just another question about lights......would it be pointless to add metal halides to what i already have to cut down on cost, or is that just not worth it? Also is there any way that you can make metal halide lights........sorry about the questions, but im trying to absorb all knowledge so i can learn this wonderful hobby.
