Wait, so i dip the coral in fresh RO water? And my petsmart never had saltwater, it stimks, but i still have Petco.
You can, but not for very long. We're talking like 30 seconds maximum.

Is a 10,000 K light enough for SPS?
What kelvin lamp?
For the most part people believe that the degree kelvin rating has very little relevance and is purely aesthetic, however this is not so, reefers tend to keep within around 10000K - 20000k with the 20000k being far more blue in colour than the 10000k which is more yellow
The K rating does though have a dramatic affect on your tank and in my opinion ( and this is my personal opinion) is almost equally as important as PAR (which will be discussed later) why? In short and to try and keep it simple blue light is the last colour to be absorbed by water meaning it penetrates deepest, so by putting a higher K rated lamp which has more blue in it you can be sure light penetrates to the darker depths, there are a few pit falls to be aware of though.
One of the biggest things reefers overlook is the depth of thier aquarium in relation to what K lamp works best, below is just a guide and is by no means a definitive be all and end all answer to what works for you as You may decide to use more than one different k rated lamp especially if your using a T5 luminaire.
Tanks 12-20 inches 10000k will strike a good balance of coral growth as well as tank aesthetics
Tanks 15-30 inches 14000k lamps will be a better option as light will penetrate deeper
Over 30 inches 20000k with supplementary lighting to light higher in the water column as this will have Little useable light Which may result in Coral growth slowing
As you can see from above there is an overlap on the 10000 & 14000k lamps so this is to a degree the users choice, these should all be used in conjunction with actinic lighting which is not just for aesthetical purposes as there are photosynthetic invertebrates (clams nudibranch etc) that need this light, as a word of caution 20000k lamps should be used wisely as over 15000k there is very little useable light for corals etc unless it is supplemented with additional light to light the shallower water, but I'm guessing there aren't that many people with 2.5ft deep tank?
