Thank you for the kind words and for taking the time to post in our thread. The 30g nano tank will not be plumbed into our current system as it will be located in a completely different area of our house.

Mike and Terry,
Thank you for the best build thread read I have ever experienced! Your painstaking attention to detail and fantastic pictures show enormous dedication to your hobby and the results are amazing! All the cool toys, exotic fish, on page 13 when the glass broke… seriously this was like reading a technical thriller! So glad that I was able to spend the last 5 hours hanging out with you guys and looking forward to more. Thanks again for all the information and congratulations on your super system!

Hey thank you for commenting on my build thread. The pictures of your stand are a huge help. I didn't have time to read the entire thread here, but was curious on your thoughts about using plywood for the tank to rest on and distribute the weight. I noticed you had one support beam in the center of your stand and wondered why you didn't use more and also verticle supports on the front and back of your stand. Do you think one is sufficient? Again, thank you for your input and for one of the best build threads ever. =)

Ha! Technical thriller :reading: - maybe we should find a publisher and make some money off this thing rather than spending so much!
Anyway, glad you made it all the way through to the "now" part!! As you might expect, there's more work to do - today's plan is to start working on the new prop tank / refugium / QT setup. We need to reclaim some of the garage - it is turning into a 400 sq ft fish room! Appreciate you sharing your thoughts and glad you found the thread interesting / entertaining.Take a look at this picture here, it shows a little better perspective of the middle horizontal and vertical supports:

In our research and consultations with a structural engineer friend or two, here is what we found: glass tanks that are constructed with bottom bracing (as most are), are designed with a bottom panel that is of sufficient thickness to give a safety factor >= 3.8. This means that the bottom panel is strong enough such that it doesn't require uniform support under it. Rather, these designs call for uniform support around the perimeter of the tank. So while uniform support of the bottom panel does increase safety factor, to do so on a tank with bottom braces is essentially overkill. For example on the Marineland 300g DD, the bottom panel is 3/4" (~19mm) thick. If you really want to get into the details about strength of glass, check out this old engineering reference How to Calculate the Glass Thickness for Your Aquarium by Warren Stillwell. Using that, we figured that 3/4" glass is more than adequate to support the expected full load with only a tiny amount of deflection:
Length = 1829 mm
Width = 914 mm
Height = 680 mm
Alpha = 0.1017
Beta = 0.5688
Water pressure (p) = 6670.8 N/mm^2
Bottom panel thickness = 18.8190 mm = 0.741"
Deflection = 0.3154 mm = 0.012"
All this assumes regular (non-laminated, non-tempered) glass, and a safety factor of 3.8. Geeky, huh? :wildone:

Monti, that is a heck of a compliment. Thank you for that! We have learned so much through reading and research of the work of others, and it seems only fair and right to share as much of our experiences to "give back" if that makes any sense. We hope you keep coming back - contributions to the thread are just as (more?) important as stuff we put out there. :beer:
Thanks Shaggy! Glad to have you here!

He was definitely one of our favorite fish ever. ------------------------
How about a couple pics of our new filamented wrasse? He's been sitting in the acclimation box for a few days while the other wrasse settle down about the new guy in town...

Beautiful shots, as usual. Did you use flash on these?

Hi Terry, did you use the built-in flash or an external? I've tried using the built-in and the photos are always washed out. Any tricks to using the flash when shooting fish? Thanks.

Hi Kenny, for those pics, I used the built in flash. I do have a remote flash as well, but for fish pics, the built in is usually sufficient enough. When taking pics with the built in, I try to make sure that the camera does not face the glass dead on, but at an angle to keep the flash from reflecting off the glass.
I used a 90mm Tamron macro lens and the camera settings were exp 1/60, F/10.0 and ISO 200.

Thanks for the info, Terry. I've tried shooting at an angle to the glass but the photo never came out right. Time to try some more
