great looking fish! could you share what you are using for an acclimation box? i need a fairly large one and don't have any luck finding one.
Thanks Nick! Ours was a Fosters & Smith, IIRC. But the one Brett linked is better!! We will probably try to build one for our next upgrade.
Mike, that Rubsquamis looks amazing. One of my favorites for sure.
Thanks Brett! He's had a rough acclimation (some conspecfic aggression), but today he was looking like he's finally been accepted into the herd.
What a beauty. I find myself becoming a bit of a wrasse nut.
Thanks 'Nukes. You've got a nice start on your collection!
mike very well thought out set up and not a lot of unneeded toys. Thanks a lot for sharing. Great addition to your fish load.
Mike, we appreciate your comments - it means a lot. We aim to help others learn some stuff that we've picked up over the years (much of it from the great builds in this forum!)
Wow, what a thread. Beautiful tank, what a wife! That tank failure would have cost me a dozen new pair of shoes for the wife.
I have a 750 gal AGE tank being delivered in 2 weeks & your tank failure scared the heck out of me.
I am very interested in your light rack. You stated you had EZTube made it?
If you don't mind can you tell me the cost & process for having them design/build for you? you can PM me if that would better.
Amazing tank!
Thanks
Andy
Terry is blushing, Andy! She really is the best wife a reefer could ever want! She not only puts up with it, she has the bug just as bad as I do, and sometimes even more. That's priceless, given our recent trials because there certainly have been times where one or the other of us has been about ready to throw in the towel. Are you going to start a build thread for your 750? That must be a daunting and exciting feeling to be setting up a system that huge! As far as our light rack - yes, we used EZTube and highly recommend them. You basically provide them with measurements (they are very helpful and flexible to work with and will guide you on some of your design choices), and they will cut the parts to your specifications. If you look back on page 5 of the thread, you'll see a copy of the drawing we provided them and what they shipped back to us along with some descriptions of the assembly. The pricing was very reasonable - IIRC it was around $120.

OK How about an update!
Since it is hurricane and thunderstorm season, we needed to update our power protection and redundancy. Over the years, we've had several incarnations of the
Playfair DIY Battery Backup Unit. With the global warming, and all the crazy weather that is increasing we decided to up our game.
I wanted to retire the old system and replace it with something a bit more turnkey and dependable. The first place to start is with your requirements. We took out the trusty Kill-a-Watt meter and measured the current draw for our main return pump and the skimmers...
The PanWorld PS200 draws 261 watts at a 94% power factor.
The Reef Octopus SSS6000 draws 68 watts at a 93% power factor.
The Deltec AP851 draws 43 watts at a 51% power factor (!)
So what we want to do is run the reef octopus and the panworld on the battery backup unit so if power fails, we will at least maintain circulation through the sump to the display and have plenty of oxygenation.
Next a few calculations:
Total Load = 261w + 68w = 329w
AC voltage at our Apex Energy Bar = 117v
AC amps = watts/volts = 329/117 = 2.8 AC amps
DC amps = watts/volts = 329/12 = 27.4 DC amps
OK, so we are going to have ~30 DC amps of load.
Now, how long do we want to be able to run on the batteries?
Well, Terry and I talked it over and came up with 6-8 hours would be about right. If we were out of town, or sound asleep and the power failed, we don't want the tank dying on us before either the utility kicks back in, or we can get the big generator out back fired up.
Alrighty, so we need 30 DC amps for 6-8 hours. This means we are going to need a minimum of 180 amp-hours (AH) worth of battery power.
Deep cycle batteries are what you need for this application. You don't want a car battery or anything like that because they won't appreciate being drained and recharged repeatedly and they also don't like to handle a low, sustained load for long periods. So typically we go looking for something like a marine deep cycle battery like this:

Next, you'll need a nifty DC-to-AC power inverter. Magnetic pumps DO NOT appreciate cheaper inverters that produce choppy electricity (aka modified sine wave), so we shopped around for true sine wave inverters that have an auto transfer switch and built-in charging capability. We came across this one, the
AIMS 1500w sine wave inverter:

The guys are the inverter store were very knowledgeable and helpful...highly recommended!
Here are all the cables and stuff that are going to be needed:

We picked up the batteries at a local Batteries Plus store in town. The biggest battery they had was a 92AH unit, so we picked up two of those:
<a href="http://www.flickr.com/photos/terryl93/5892548509/" title="nt 1186 by terryl93, on Flickr"><img src="http://farm6.static.flickr.com/5034/5892548509_2d17668961_z.jpg" width="640" height="425" alt="nt 1186"></a>
and wired them in parallel (positive to positive, negative to negative). This has the effect of keeping the voltage the same (12v DC) and simply doubling up on the AH provided to the inverter...so we should end up with 184 AH:
<a href="http://www.flickr.com/photos/terryl93/5892548953/" title="nt 1187 by terryl93, on Flickr"><img src="http://farm6.static.flickr.com/5191/5892548953_48187076d4_z.jpg" width="640" height="425" alt="nt 1187"></a>
Here they are all snuggled in the plastic cases:
<a href="http://www.flickr.com/photos/terryl93/5892549365/" title="nt 1188 by terryl93, on Flickr"><img src="http://farm6.static.flickr.com/5274/5892549365_7727472eda_z.jpg" width="640" height="425" alt="nt 1188"></a>
Next up was to stack the battery cases, put the inverter on top and wire it up. This model has a wiring strip for the AC connections (AC in, AC out), and on the other end is where you hook up the cables from the battery bank:
<a href="http://www.flickr.com/photos/terryl93/5892550393/" title="nt 1191 by terryl93, on Flickr"><img src="http://farm7.static.flickr.com/6043/5892550393_0d36d6bfd0_z.jpg" width="640" height="425" alt="nt 1191"></a>
Last step was to put everything into place and wire it up. We attach the batteries to the inverter, plug the inverter into the wall, and plug the pump and skimmer into the inverter. Now we have got some great peace of mind for the upcoming summer season!
<a href="http://www.flickr.com/photos/terryl93/5893118742/" title="nt 1195 by terryl93, on Flickr"><img src="http://farm7.static.flickr.com/6046/5893118742_be66572edb_z.jpg" width="425" height="640" alt="nt 1195"></a>
This is not an inexpensive solution by any means! These AGM batteries are pretty pricey, and so are the true sine wave inverters, but considering the cost of replacing everything in the tank, the insurance policy is worth it!!
Thanks for watching and have a safe and happy Fourth of July!
