I have been running an ecosystem set up with a 24/7 light period for 15 months now. My caulerpa has never gone sexual. I thought one of the reasons we light 24/7 was to allow the algae in the refugium to outcompete the algae that may try to grow in the main tank. It seems to me if you go to...
Mine never really worked properly. CO2 continues to flow even when the solenoid is shut. I tired cleaning it out with an air blast but it still leaks.

I had a similar problem. The P3 outlet stopped working after about five months of use. I had to send the unit back to Red Sea in Arizona. That was four weeks ago. I still haven't heard back from them. Since then I've been running all four powerheads continuously.

I had a 400w Iwasaki with two 110w vhos mounted above it. I found it way to yellow for my taste. This past weekend i added another 110w actinic and moved all three below the MH. The color is much better now.

Reef Gallery in Oakville. Ornamental Aquatics in Dundas. Strictly Fish in Georgetown. Of course if you don't mind spending more money for the same stuff you could try Big Als in Hamilton or Mississauga.
