Why do we assume a large return pump is needed?

Well, now that my 'banning problem' has been resolved (thank-u-mods)...
wetworx101 >> Herbert T. Kornfeld >> hahnmeister
Im glad it helped. I am seeing more people planning smaller return pumps these days as well. I cant take real credit, but after running this thread, I have seen MANY MANY more new reefs with smaller return pumps, and many others suggesting small return pumps to others...something that was very rare before unless in a UK/German forum.
Right now I am busy applying my 'efficiency skillz' to a new water cooled computer I am building. I am using 6' sections of star-finned heat exchanger pipe to create perhaps the largest passive water cooled personal computer setup ever. Should be fun.

Have you seen that fan mod? That was a step in the right direction. Im not into modding pumps though...at least not the elextronics side of them. The imps and shrouds are fair game though.:rollface:
As for that square skimmer jnarowe, is it built yet, or are you still planning? If you are skill building, I see the designs you have in your gallery... Have you considered making/getting Spazz to build a thermalformed piece? On my 8x8x48" tall square skimmer I used a 8x8 square of 1/4" acrylic, then pushed a 4" pipe into the center while heating the piece in the oven (like Spazz does it). The result is a square base, but a very gradual slope all around (no edges to bond or create turbulence) that leads to a regular round riser neck. It works great!

I knew it was you!! Maybe I am the one that outed you by mistake?
Anyway, I built the skimmer already and spazz won't make anything for me. He has somehow developed a dislike for me which is unfortunate because I really wanted one of the Sequence needlewheels. He gave me a lot of crap about my square skimmer but as I have posted before, cylindrical skimmers are not really DIY for the average guy.
Anyway, you can see a few pics of the skimmer by clicking on the red house and going to the skimmer page. I baked it in the oven and got a nice transition to 6" tube. The riser is 2' high and the body is 14" x 16" x 53" and it really works well. I am currently using an Alita 100 and burning 120W to skim about 1,100g of water. Not too shabby.
However, I am working on a mod that if it works well, will blow all the needlewheel guys out-of-water. I have a design that is actually DIY, rather than CNC DIY, if you know what I mean.
Can't discuss it any further because I really want to make sure it works before I mouth off about it. If it does, I will post it and the entire needlewheel business will disappear. :lol:

Oh yeah...I remember seeing that beast before...skimmate popping out everywhere. Looks great. I see you did do the thermalforming of the riser neck...looks nice and slick. Glad to see its 'blowing away the competition'.
Thanks for the info RGibson. The starfin pipes I am getting a quote on are from here...
http://trueleaf.net/greenhouse-heating-finned-products.html
I figure that 4-6 of these in 6' lengths on the wall (across from the A/C outlet as well) should do the number... but Im still up for suggestions.
This is what the industry has to offer for passive cooling...great for silence, but not the best for overclocking...

RGibson: I am not really sure yet. It will run with the same air pump with less or zero back-pressure and a Sequence 1000 series pump. I am guessing that it will come in about 250W and quadruple its efficiency, but that is just a guess. When I get it running I will measure the electrical draw and post that as well.
And may I comment, what the hell kind of computers are you guys cooling? NSA sniffers I bet! :lol:

I suppose Calfo is pro-low-flow as well. Hes mentioning it all the time as of late.
As for the computer...Im just sick of noise. I run some pretty hot stuff, and that means 4-6 120mm fans spinnin' away on a case...and my new rig is a Socket AM2 x2 4200, and some of these new chips are supposed to be awesome overclockers (like 700mhz over stock and completely stable) if you have the right cooling (read>water). The computers also generate some heat (700watt PSU, 2x 7900GTXOC video cards, 10,000 rpm drives, etc) so I was thinking that running the radiator to a remote location in summer (outside) would mean less work for the A/C. As is, the office, where my computers and the woman's reside, gets its own A/C unit because its the hottest room in the house.
Water cooling in PCs is done for one of two reasons...for noise elimination, or for getting an overclocked processor to not fry (okay, maybe 3rd reason: its fun). For better performance, radiators with lotsa fans are used...kinda defeats the noise thing then. And passive units that exist aren't as effective at cooling. I want both. I want silence, and excellent cooling. That means I need a very large passive radiator...larger than anything produced for the consumer market.
Eheims are pretty commonly used in water cooled computers (aquacomputer.de and innovatek.de have custom made 12V eheim pumps made for them) because of their low noise, high reliability, and low heat transfer. Besides custom made 12V pumps, the 1250 is an ideal pump for larger setups like mine when used with a cheap 120v-12v pump relay. I figure I already have a few 1250s just laying around, making the reservoir should be easy since its just like a kalk reactor...but in this case Ill make mine 3" diameter and 6' tall to match the finned pipe in size.
And its just plain slick...check out some of this stuff.

The water cooling PC market is booming...but for 'designer' stuff, you pay designer prices (like that $300 innovatek passive radiator)...so I figure Ill make mine better for a fraction of the cost. Unlike CPU coolers which change every year or so with new processors and sockets, water cooling blocks can last decades (just swap out the retaining clips), so its an 'end all' solution...or at least until processors exceed 300watts in thermal output. Heck, I should be able to run a few computers at once with this setup.
