Well, it's been a VERY long time since I made an update to this thread, so I think it's time.
Sadly, over the last few months, my tank has suffered. I lost my Naso Tang and two of my Engineer Goby's. No worry though, I have plenty of other fish and we all know, there is no fish purchasing in my future any time soon. Just means I have to feed less now and that saves me money lmao.
I have been needing to replace the sump light for a while. I just had a 60w equivalent CFL on my refugium since I built the sump (if you remember, I built the sump from scratch). Well, things are just not growing in there, in fact the only thing that is growing is red hair algae. With it growing down there, it's keeping it out of my display tank. But it's still choking out my Chaeto and Caulerpa even though they are hanging on. So I decided that I needed more light, and I had just the lights to do it without spending any more money!
The lights I'm talking about are the lights that I built and installed in December of 2012. They are a retrofit kit consisting of 3w LED's. However, I didn't need the blue lights in the sump so I'm only using one driver and powering the white and UV LED's. The video at the bottom of this post will show you what these lights look like.
I decided to do a little custom coding on my Apex controller and I have the sump light ramping up while the main display lights are ramping down and the opposite in the morning when the lights are coming back on in the tank. This is a whole lot of light for such a small little refugium lol. But I can assure you, things are going to start growing now. Not only am I putting white light in there (less red spectrum than what was in the CFL) but I'm putting much more light in there. I'm covering the whole refugium rather than just a small portion of it.
So I created three new profiles, sump_up, sump_dn and sump_day. sump_up will ramp the lights from 10% (the minimum for the lights to come on) to 100% in 40 minutes. sump_day just leaves them on at 100% power all night (should have called it sump_night, but that just didn't feel right lol) then sump_dn will ramp them down in 40 minutes. Then, I put it all in the outlet for my variable speed controller which is nothing more than a cat5e wire and put in a little code in there and presto, we have massive light in the refugium! We will see how my macro algae does.
It sucks that I lost my tang and my goby's but it is what it is. The corals that are in my tank are doing great. My hammer coral started with two heads and is over 20 heads now. The Acro I got from Matt is double in size (grows very slowly), the green stars are out of control as is the monti. Those two are all over the place and I'm about to start some serious pruning! But that is for later.
Here is the video on the lights. If you all are still even interested in this thread, I will post up some more pictures. Also, there is a video of the refugium the way it was right after I built it and got all of the plumbing the way I wanted it. still working like a charm!
