Skimmer, TALL skimmer vs short under cabinet type ?

I started reefing in the late 1990's, but found myself in & out of this beautiful hobby's with others. So, now I'm planning on building a 125g in-wall backing up to a reef room. On that same wall and back room, I had my first reef, a 75g. I built most of the lighting and filtration system myself including my skimmer. I went to the hardware store and bought a 6" diameter x 5' tall. I reduced it down to 4" clear acrylic tube x 6" reaction chamber to see the bubbles. A company that has a lot of acrylics sold me 10'' diameter x 10" tall piece to use as the collection cup. I bought a 2" x 10" piece of lime wood which produces tiny bubbles, perfect for air driven skimmers. It's a hardwood that can live up to 1,000 years. I would cut them 2" x 10" lengths and once per month I would remove it to clean the slimy scum off and replace, then put a new one in every 3 months. With a large air pump I would get 12" of froth of the worst smelly crap in the collection cup. I finely made a lid and a carbon filter to help. lol

Question is, I still have that skimmer under my deck from 2004. lol
Anyway, should I make another or use the Vertex 150 I bought at a auction ?

Prove me wrong, but I feel that there's a lot of great company's making good skimmers, but their niche is short under the cabinet skimmers, which is great, but I feel the loose the dwell time,... that's needed to brake down the fatty acids, protein's etc. which we want to remove before returning the water back to the DT. My 75g was loader with corals and fish and very well fed, with not much in nitrates.

I'm a tinker and really like building my own equipment and watching it work. What do you think between the short vs tall skimmer and their dwell times making it a better skimmer, etc. ?

I don't know which is better, what do you think ?
 
When I run one, I run a reef octopus that fits under my stand. That’s the only skimmer I’ve ever ran, not the only one I’ve bought, but only one I’ve actually used.

Anyway, the DIY skimmer sounds like massive overkill unless you’re running 1,000+ gallons (I could be over-rating it but that’s the only time I’ve seen massive skimmers). I also don’t know how common lime wood is nowadays as most skimmers that I’m aware of do not use the wood block air stones.

With that said, it seems you are aware that nowadays, some nutrients (nitrate and phosphate) in your tank are desired. So while I can’t answer the short vs tall, for my tank, I have a short and rarely use it.

You kind of answered your own question about which way to go. As for dwell time, I think that has been managed by needle wheel impellers muscling air and water together reducing the need for a tall column. I still think cone skimmers are a gimmick (even though I run one) but maybe that's another conversation.
 
I say use the one you built if you can still get the limewood and parts. Worse case you can always put it back under the deck. :)

I made a skimmer out of (4) 5 gallon buckets stacked on top of each other and used a venturi. It actually worked very well but was ghetto and I wanted something that was rugged so I swapped it out for an external Reef Octopus skimmer. I am like you and if I can DIY it then that is the route I want to go.
 
Lifereef?

I am running a SRO-8000 cone skimmer myself.
 
Taller is always more efficient because it increases contact time.

Skimmer got smaller because pumps and the way they make air got more efficient so they do not need to be as tall. They create more bubbles. You take these skimmers and make them taller they will remove more too.


I had a Vertex 150 and didn't like it. It skimmed well but touchy and overflowed allot.

Please tell me you have pics of the ghetto skimmer. I want to see it.
 
ASM is the other that comes to mind. They come in many sizes.
Find a used one and rehab it into what you want

I purchased a Lifereef unit and run it with ozone as well as the large Reef Octopus. Mine is 36 inches high. Lifereef makes extensions to make them taller as well.

Those are the ones I looked at.

I built a 6' tall skimmer years ago (7' with cup I imagine). I started off with a recirculating needle wheel design. Then later migrated to fine pore ceramic airstones and a huge alita linear air pump. Both worked. The skimmer was a monster. I got tired of cleaning skimmer cups and shut it off one day. Five years later I cut it apart with the sawzall... Fast forward a few years and I decided to skim again and this time purchased a Reef Octopus Regal.

I will simply say this, the Regal performs wonderfully. I never have to adjust it. The DIY skimmer was a LOT more fiddling and I am not sure that it performed much better given the space it took up.

I used to be a big DIYer, partly to save money, but mostly because I like to design and build stuff. That got old, not mostly just buy stuff.

The Warden for scale...

More than one passerby honked and screamed "Nice Bong Dude" during construction in the back yard.
