Having plenums in my tanks have been a good experience for me. I was at the Goemans lecture and I can't tell you for sure if he was woooing or trying to woo anyone. I do recall he was very precise in his directions on how the plenum was to be made.

He included info on the material to be used for the screen, even the mesh size. The substrate to be used with a plenum had to be special reef grade aragonite sand. He explained that should these specifications not be met that it could lead to problems.

There is a video in our library of this lecture. If it is not available anymore I have a copy if anyone wants to see it.      ]]> Mon, 01 Sep 2003 10:30:25 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=7626&title=plenum#7626 <![CDATA[Plenum : DSB&#039;s all the way! ]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6805&title=plenum#6805 Author: utahtaper

I missed the Bob Goeman presentation, in fact I missed him altogether.
When I first set up my tank I did not have a DSB or plenum. I could not keep a fish alive. Every fish I bought contracted ich and died. I ran into Tom Miller at the LFS and he explained the plenum concept and directed me to his website. I tore down my tank and followed his instructions utilizing a plenum. That solved my fish death problem and as I started buying corals, they lived. So - that's how I started and continue to use a plenum. It is my opinion, that a DSB does the same thing - especially if you seperate the upper and lower layers to keep critters from disturbing the deeper sand. At that time, the internet was not as easily accessible (nor was there as much info) as it is today. Had I known then what I know now - I would not have set up a plenum.

I went to Bob Goeman's presentation on the "plenum" I felt that his scientific explanations were mostly non-sense, speculative and a demonstration of poor laboratory technique (and experimental desiqn). So, as you can tell, I'm not impressed. His words (my opinion) I felt, were to woooo hobbiest who have little/no lab training (to sell a book?). Now he is into this eco-aqualizer scam (Far intra-red hog wash does not "condition water molecules"! This drives me nuts!!]]> Mon, 04 Aug 2003 10:03:46 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6786&title=plenum#6786 <![CDATA[Plenum : Brad A. wrote:Plenum=waste...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6782&title=plenum#6782 Author: Jake Pehrson

I see no need for a Plenum. I have had a DSB in different tanks for 18 years. My DSB's have been about 3" - 5". I have had no animals mess with the bottom layer of sand. The benefits are the same and even better IMO with a DSB compaired to a Plenum.]]> Mon, 04 Aug 2003 08:45:01 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6779&title=plenum#6779 <![CDATA[Plenum : There are so many successful tanks...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6695&title=plenum#6695 Author: tomason

There are so many successful tanks with and without a plenum, so neither method can be called "wrong".

But because there are so many successful tanks WITHOUT, I didn't bother for my tank.]]> Fri, 01 Aug 2003 15:45:17 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6695&title=plenum#6695 <![CDATA[Plenum : Plenum=waste of space. ]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=840&PID=6694&title=plenum#6694 Author: Brad A.

I thought the time was ripe to start another controversial thread!
What does everyone think about the use of a plenum under a DSB (or not so deep sand bed) to encourage anaerobic bacterial growth?
I have had very good luck using plenums. I have yet to have one blow up and cause major problems in my tanks. As I learn more though, I'm beginning to wonder if they are an unnecessary step in establishing a biological filter in my aquarium. I can't imagine ripping my tank down to "undo" my plenum. But - next time ...
