You can circuit the 2 24v fixtures together yes as they are the same line voltage youll come out 48v series im a electrician so i can vouch but make sure its in parallel ++ - - if you cross the polarity youll drop the voltage and surely mess something up good luckHeat.. it's going to be an issue for both tanks. Outside temperatures are slowly increasing and these T5 fixtures are obviously dumping more heat into the room, and directly into the water. I have left the frag tank with an 8 hour T5 photo period (2x 24W ATI Blue+), and it is already hovering near 80º F during the daytime with an ambient outside temperature of 20º C (~68º F). The DT with a two hour T5 period after work is currently rising .6º F in that time, and I can only imagine if a similar 8 hour period daily would also be driving the tank to near 80º F.
My solution has always been evaporative cooling, as it's both the easiest to implement, and the most practical. I don't have an AC unit, and leaving the windows open with the fans on all day while I'm at work is also out of the question. The only question at this point is how to go about wiring in the fans. Do I source out some more 24v and wire them into the second EB832 24v DC port, or just go with something that's already an out of the box solution. I have years of 120mm fan use from my PC watercooling days, so that form factor and noise profile is well known. Settling on 120mm for the sizing, and roughly 30 dBA for a noise profile, I lucked upon these AC Infinity fans on Amazon.ca that are 50CFM @ 30 dBA direct AC plug, or 20 - 70 CFM @ 16 - 38 dBA with their controller. I've since installed a single fan on the frag tank after work today and the temperatures have already stabilized back down to 78.2 (the turn-on point for the fan), but I will be ordering the dual fan kit to see if I can knock that temperature down while using a slower speed for complete silence. If that works out, it will be replicated on the DT - and there is a perfect amount of room left in the Aquaticlife T5 hybrid fixture to fit them.
The only problem with this solution is the requirement of an EB8 / EB832 / EB4 apex plug, and I'm already past maxed out for each tank. Still trying to figure that out, but I've put the feelers out locally to see if I can find a used EB4/8. While I had thought about going the 24v DC route again, the fans in that profile are not as easy to source, would require more DIY and aren't natively adjustable without further DIY. As well I can always make use of more Apex EB ports, so another bar just makes sense.
In livestock news, I believe the pink streak wrasse has passed away. I had seen no issue with it until one day it stopped being cryptically out and about, which was about four days ago. The social wrasse had never really shown any attention to it, nor any other tank mates, so I'm wondering if there is something more at play (after the loss of the Tailspot), or simply an age issue? Everyone else in the tank seems fine, so it is puzzling. The hard thing about these is if a fish does pass, by the time you notice the body is most likely already processed by the clean up crew. I've looked all over to make sure it didn't jump while the lid was off, but I haven't seen a Mr. crispy on the floor or behind the tank. I really liked that little wrasse, and had owned it for over two years. I'm hoping it was just age related, but we'll see..
The greenbanded gobies are so tiny, but also so spunky. Two of them most definitely do not like each-other and I have seen some physical altercations, but the largest of the four comes along and breaks them up quite quickly. I'm not sure if those are little males or females, or just such similar size that they are being aggressive, but so far there is no lasting physical damage. Feeding these guys is the real problem so far, they are only eating PE Calanus. Thankfully I have lots from the combo pack of PE Mysis I purchased last sale, but I'm hoping they can eventually progress to larger foods like the PE mysis pellets that everyone else eats. They're in the tank with the blue star leopard as the 20L system is running but I want to give it a solid time to get the biofilter established before it's filled with fish for copper. The gobies are so small though that I feel they will be the last ones going into the DT, and I may set up the 10 gallon IM fusion again solely for them to grow larger in after passing through quarantine. Once they get around 1.5" I'll move them to the DT, and hopefully by then they've settled whatever squabbles are going on . This video has some bad quality, but shows the little guys eating for the first time when I tried Calanus, or at least mostly eating.
The rest of the livestock is d0ing great, the frag tank acro frags and my DT montis are finally getting full colour back, and the chaeto in the DT is starting to take off under this H380 beast. I'm only running it for four hours at night so I don't nuke the cheato, but the mass is visibly quite a bit larger already, and the DT is still reading low phosphates (~.02), and zero nitrates. The only thing that's somewhat lacking are water changes, mostly due to space issues with all the junk I have going on in this place, but have to make a concerted effort to get back to at least 5g weekly.
