Pics of the new skimmer.......

Shot from the front.....The pump isn't installed yet......I did play around with the broken fitting, and you can see in the pic I did use a little super glue and glue it back into place which appears like that's all they basically used, but for $800, I want it replaced.........

A large Dunkin Donuts coffee for a size comparison........

A side shot showing the output of the skimmer with gate valve.....The union in the center is the water input to the skimmer, and the ball valve far left is a drain for the skimmer......

What voltage ELN are you taking about for whether they are plastic or metal case?

Awesomeness!!!  That should grab a little waste.  And I must say that I just love how the pretty flowers seem to accentuate the luscious red color of the skimmers base and other necessary parts.

 

But I think we need to see a full shot of whatever you got hanging there on the back wall.  Is that a poster, wallpaper or something?  It looks cool.

I thought this was interesting.

 

"With up-to date LLC and synchronize rectify technology, HLG-240(H) posses up to 94% of high efficiency, so it can be cooled by free air convection from -30° to +70° ambient temperature and meets the requirements of outdoor assembly."

"These high efficiency power supplies are very suitable for LED street lighting, outdoor electric display, LED decorative lighting, indoor/outdoor LED lighting...etc. Besides, they are also good solutions for general applications at outdoor environment with high dust and moisture. "

 

Looks like you are going to have to try to keep the temp of whatever enclosure you put them into below 70 degrees for effective convection cooling.

This one says

  -40~+60°C

So up to 140 F. That's better

I was seeing temps of up to 120 degrees Fahrenheit on mine when they were pushed full steam.  I don't have any intentions of running mine full steam during mid day brightness.  Maybe 70% max should be all I need at the most as far as the scrubber build goes.  Will definitely get some more readings when I run them at those operating temps with the driver fan going at the same time.  I bet I'll see a huge drop.

I'm interested as well to see your readings when you have everything wired and set.....

Too many posts to keep up with! nice skimmer Shawn. And keeping a driver under 140*F shouldn't be too hard.

Thanks Al.....Plan for the weekend is to get the tank drained down, so I can remove the plugs from the back of the bulkheads in the back panel of the tank and install the plumbing for the OM CL........

I'm not sure if this info is useful, but I'll share anyway. My one LED unit that does not have a working fan gets up to 143 when the lights are running at 100%. Now, the unit with a working fan gets to 126. The fans are optional, but I am thinking about about 2 more fans that can cool the units a little better. 

 

Your tank is really coming along. I can't wait to see it all put together.

Thanks Krista......So 1 of your units doesn't have fans.....I would have thought they would all have been fan cooled.....Al drew up some fantastic plans  for my heat sinks.....Each heat sink will be cooled with (3) fans.....Should be more than adequate to keep the temps down...The big question is keeping the drivers cool, since I want to mount them away from the heat sinks and leds and put them in a control panel......

I can't wait as well Al......Planning tomorrow night after work to start the drain down process and at least have the elbows and such in place before bedtime Friday night......Would love to be able to refill the tank Saturday afternoon and fire the OM and see what increases I've gained......I have decided to run a SSB, but might have to do some manipulating of the CL lines to keep from blowing sand around.  

 

LR I kept some pieces from my 240 stored in a Rubbermaid container....Possibly might start digging them out and toying with some rock work and seeing if I might need to add more LR.....Not really planning tons and tons of rock, but looking for an open structure with lots of places for corals and room for them to grow into.....still at the same time plenty of swimming room.  Also a main goal is to be able to keep a carpet anemone down the road....
