how can i tell if my pc bulb is true actinic

[AlienAnchovies]

all its says is "blue" they are the lights that came with the JEBO power compact i got for $30

and on an other note, after jokingly placing the pc fixture over the 7 gallon nano my xenia went pulsing nuts
oh and how long should i wait before adding corals to my my 20 gallon
i mean how long does a tank take to cycle

True actinics are 400 nm, most pc bulbs say 7100K which is just a blue light

There is no set amount of time that it takes for a tank to cycle. One of the most important things you can buy in this hobby is a good test kit. When starting a tank you should keep an eye on the ammonia, nitrate, and nitrite levels. And, one of the most important things you can do before and after getting into this hobby is read books on the subject. If you read a book on general saltwater tank/reef keeping it will explain the cycling of wastes and chemicals in a tank. This of course should have been done before starting the tank, but your situation is very common.

I bought one of the true actinic PC bulbs from hellolights. It's very "purple" in color when lit as opposed to the blue PC bulbs. It looks better than the blue ones IMO, but not as good as the vho.
