I am getting next week a 250 watt hqi 10000 k mh, to replace lighting listed below, I will use 2 65 watt actinic p.c. with it. That puts me at like 6 plus watts per gallon, is there any problem with that????

6 watts per gallon is a great number! You should do well with that. Make sure you get actinics and not just blue bulbs for the PC.

I use to be a right-winger on W/g, but recently have seen that's not really the important part of the lighting. Sure you need at least 3 w/g for any type of lighting. However, factors like type of lighting, Kelvin, and CRI all affect what you need for lighting. I have a 20H that has 20 W/g, and does great, however, I also have a 75G that only has 7 W/g. I think that MH is a neccessity, as well as the right Kelvin.

I was concerned with the actinic, or blue problem with the bulbs for the pc so I wrote to custom sealife, who, I have 2 of their bulbs in my tank now. And the MH will be 10,000k so if the actinics are actinic I think I will be set. Here is his answer to my question of pc actinics.....................................
Thanks for writing. There is a lot of confusion as to the term "actinic" and the differences between the spectral output between different types of bulbs. The term "actinic" refers to a spectrum that is maximized in the blue end of the spectrum. The term "true" was actually connected with the first high output bulbs that utilized special gases and phosphors to create a light that peaked at a very low wavelength, giving it a purple/blue appearance. This light was valuable due to its ability to penetrate deep into the aquarium as well as into the tissues of the organisms. The aesthetics of the aquarium were also improved over the harsher yellow lights that had previously been used. The term 03 is also synonymous with the word "true" and both generally refer to an actinic bulb that peaks in the 420-430 nanometer range. Our actinic peaks around 460 nanometers. This is also the range where photosynthesis is activated.
Our bulbs are not "painted" and utilize a special gas mixture combined with rare earth phosphors to create the actinic wavelength. Many years ago a competitor used this statement to scare people from purchasing our lights, but unfortunately rumors stick. Our bulbs, while different then the VHO actinics, will give a more natural look to the aquarium, as our bulbs simulate the natural environment.
If you have any more questions, please let me know.
