Im really liking the side-cabinet built into the stand.
Its nice to have a shelf for all your food/additives/other junk and the control panel is great too.

Good Stuff Bill!

MAn that looks awesome man , love the stand I made one for my 75 gal a couple years back....

Thanks for the kind words everyone!

The tank is a 120g AGA, 48 x 24 x 24 and the sump is a Seastar 40g long, 48 x 12 x 16.

I'll give more details with pics as we go. :mrgreen:

I had two main goals when building this system, not to have stray light coming out the back or top and little to no noise. I don't have any stray light but the noise is not quite where I would like it to be.

The biggest challenge with having a completely sealed unit is heat. I have the Mag 9/return and the Dart/CL in the crawl space to reduce noise and to help keep them cool. I also have experimented with a exhaust system to get the hot air out. I suck it out from above the display where the lighting is and blow it out the side of the house. It works quite well now, it comes on when the MH’s come on and off an hour after the MH’s go off.

When I was trying to get the sump drilled for the return I could only find a place to drill 1" holes and I wanted at least 1 1/2", so I got two 1" holes drilled and T it into the pump. After I had it drilled a glass company called me back saying they can go up to 3", oh well at some point I will be upgrading the sump and pump. Maybe :mrgreen:

You can see the two black bulkheads in the back middle of the sump.

And in the crawl space you can see the pumps and plumbing. First the Mag 9/return and then with the Dart/CL.

I was originally using a inline ducting fan rated for around 80 cfm's and that wasn't doing it so I went to a 309 cfm fan I got from Chin Lee. Thanks Chin I haven't forgotten about that. :wink:

Here you can see the flexible aluminum ducting.

This is the old fan in the c/s inline with the ducting and then removed from the ducting.

New fan

I first set it up like the old one but vibrations were going through the floor.

How it is now.

I have it vented through the side of the house using a dryer vent.

:lol: It says 120 right in your title. Silly me. Anyway, looking very good.

Cheers,

Love the finished look.

How sealed (air tight) is the stand? Maybe you want to try adding a transfer grill for the exhaust fan to draw more fresh air in. That may help your heat issues.

I thought you've had that ritteri longer than 1 year? Did you have it in your 40g before? Or am I mistaken?

Sorry for the way late reply. I’m not getting notification on replies.

Tony – yes your right, I have had it for just over 2 years.

Lando – I don’t have any heat issues at the moment, I have considered that.

For a CL I am running a Dart, I don’t have it on any timers or pattern changers. It’s just a steady flow from right to left 24/7. It seems to work, I think I’m getting good growth, color and PE. I do however adjust the nozzles every few months.


Here are all the pieces all laid out.

The intake just goes over the top of the tank and the manifold is just above also. This way I did not have to drill any holes in the tank.

I just used some locline fittings that screwed into the PVC fittings on the manifold.

Wow fantastic photos Bill! Your side equipment storage cabinet puts me to shame :redface: Its so organized and well thought out. Makes me want to redo my setup.
