- A 20000K bulb will be very blue and consequently have relatively low PAR output. It will be roughly equivalent to a 150W 10000K but with the heat output of a 250W. Depends on your current lighting setup but I doubt your inhabitants will have much prob adjusting. As always, shorten the photoperiod and gradually increase it to be safe.
- IMO Tanks don't really need actinics. People need actinics. But the 20000k should be blue enough by itself. - Temperature issues are very specific to each individual system. Ambient temperature, tank dimensions, and configuration of pumps/powerheads are significant factors in addition to lighting. Just because someone has the same lighting and doesnt have temp probs does not mean that you will not. HTH

And don't forget that a canopy will have an huge effect on the water keeping a high temp too, along with a humid place. My tank is placed in the basement in the spare bedroom and the sump is in a back room where ist cool all the time. having the sump in the basement is a great place for the sump you can usually have the humidity around 30-40% lower in the basement then under the tank in the stand.
P.S. OMI I think that Pc dont keep thier strenght very good, the power is usually gone around the 5-6 month period HTH
