Some more detail on my impeller mod. and a link to the DIY thread cause this could work on many pumps.
http://reefcentral.com/forums/showthread.php?s=&postid=8008968#post8008968
I cut the gutter guard into 4 circles about the same size as the paddle wheel that it came with. I removed one of the 2 paddle wheels. I stacked all 4 and attached the 4 gutter guard wheels with 3 small zip-ties to the 1 remaining paddle wheels. Then I tested into good I need to up grade a few things. After I change the flow-meters fittings, hose, venture... to all bigger sizes I tested it again. WOW 30 scfh. I think it was still limited by the venture i.e.; I think it can pull even more, maybe allot more.
I don't think I have come close to finding it limits yet. It is simply plastic gutter guard it can be cut with scissors in a bunch of different shapes, and stacked in a bunch of different configurations, i.e., small one, big one...... or smaller diameter verse larger diameter....
I put this pump on the skimmer and tested it again. Even with the small id plumbing (5/8" in spots te clear tube in the body) it was pulling 24-25 SCFH. To put icing on the cake the water movement was over 30% less than before. MORE AIR, LESS WATER, HORAY BUBBLES! The water flow is under 400 gph.
If I restrict the water intake the air flow goes down, but it does not go down at the same ratio with the water. I don’t no the numbers yet but they seem very good. i.e.; if restrict the water uptake to say 200 gph it still pulls 20scfh I (I have not test this but it just seems that way.). That part just to points out the venture can use some tailoring. If I just play with the venture I could get it up to 40 (maybe) and we can still play with the gutter guard also.
removed 1 of the two paddle wheels (not an easy job)
not the same pump better pump for the photo OTP2000

Back the truck up here! We do have a lot of pumps, these pumps are slated for a skimmer. It is hard to sell a skimmer with out a pump to go with it. When we placed our first couple of orders, we had a 1:1 relationship of skimmers and pumps. I had told him we were ordering extra pumps so that we could offer them.

yeah Spazz, i have lots of questions myself. i did not even think about burning up the motor. i believe the wattage has to be less than before but with no watt/ampmeter, im not sure. ( wait i do have a old craftsman analog amp meter i probably have not used it in 20 years. Humm).
My other questions is diamter, is smaller better? is some space in between each layer better? is a star patarn better? is less layers better? And then theirs the Venture ... I almost cant sleep. Almost
Thats why i start another thread in the DIY section just for this -"i dont no what to call it wheel"- and these kinds of questions. i figure the more people playing with this will help answer this questions faster.
What i do no it make this $200 skimmer Rocks.
(actualy with all my time in this thing it probably a $2000 skimmer by now :lol: )

How much air flow
How much air flow
Roland, You know I'm not sure how much air I want. I'm not real knowledgeable on skimmers. I do know I want it to be as efficient as possible. I don't have a scf guage (or what ever you call it?) I have it in a vinegar bath right now and I'm thinking I may have drilled 1 to many holes in the 90 in reaction chamber. It appears to be pushing air clear to the bottom of chamber. Which is making out of the output and into the main body of water in rubbermaid tub. I'm thinking I might have to plug one hole. When I drilled the 90 I went thru the top and bottom of 90 with a 12" 5/16 drill bit. I also drilled 2 1/4" holes perpindicular to 90 at slightly diff. angles. I does appear to be producing a tremendous amount of air as the chamber is pure white with very tiny bubbles. The water is fresh though not salt, different density so will see. I would apperciate any input you might have.
Where can I get an air meter?
Thanks, Robert

Robert, initially the issue was that the pump could not move enough water to suck in very much air. What the boring out of the elbow,porting the pump, did was to allow the pump to move more water. It now has no problems moving water out of the housing.
Now you want to work on the ration of air to water. You can do this by making the venturi more restrictive, etc. (IE, you dont have too much air right now, you've got too much water, which is why the air is being swept down to the outlet)

Me too. I would like to see pics of Rich's whole set up.

I'd love to see pix also. He gives a lot of opinions around RC and seems to be very good at ignoring posts that are inconvenient for him.

Fliger, what the heck does this post have to do with Reef Octopus mods?
I've said repeatedly, and multiple threads, I moved in early July, and lost most of my stock due to some heat issues in the new apartment. I've told you that 5 or 6 times now. Hows that for ignoring posts?
Now, if you dont have any comments THAT ARE ON TOPIC, stay the hell out of this thread.

pictures of the mod are on topic, and I have already posted them, if you'd look back in the thread.
pictures of my tank (which looks awful) are not.

Just for the record I am referring to this
I'd like to see the pictures before I make a decision on Chris' skimmer. Obviously you are not obligated to do so, but you said you would and I'm just wondering if you will. Sorry if you think that is OT. And sorry about your livestock.
You people are so damn demanding its ridiculous....

Honestly fliger, the whole "take pictures of the meter" thing is ridiculous. Its a shot at my credibility, and I dont like that. I've got no vested interest in fleecing you here.
I've posted multiple pictures of my modifications. So has roland. We've given SCFH numbers. If you dont believe us, fine, but between working 60+ hours a week, 10 hours a week of commute, playing in charity softball tournaments, cleaning out my second apartment, etc, I just dont have time to pull the skimmer out from under the tank, set it up in a rubbermaid, and take pictures of a flow meter JUST to prove things to you. My sump is too crowded, and has no lighting, and I just can not get the damn camera to focus on the meter inside the stand.
And even if I do find the time, I'm not going to waste it doing that, I'm going to put a threadwheel on the pump, and see if I can get it to draw 30+ SCFH on the skimmer, and not just in a tub.

Dude, take the meds. I was just asking for a picture that you said you would post. I think you might be a little paranoid with that "shot at my credibility" comment. Yowza
Apologies for all on the thread that it took this turn - I was just looking for a pic since clkwrk and I are in the middle of a skimmer swap (he's a neighbor)

I THINK mine is 1/4". It is pretty huge, although I'm not sure how much difference it really makes. The output of the pump is the biggest issue, and any flashing issues in the venturi

Yes Rich, from me, this is a shot at your credibility.
I don't believe the things you say are true. I WANT TO SEE. Sorry if it bugs you, maybe you shouldn't be so opionated if you don't want to back up the things you say.
This is very on topic. Many of us are considering demoing an RO, and you being the main person who screams for recognition for this product, should provide evidence to back it up. I WANT TO SEE RESULTS!!!! And if you're not gonna show them, your credibility is shot.....
And as far as working goes, you're not the only one who puts in 60+ a week. Try selling advertiseing..... I eat, sleep and breath my job. Its a 24 hour a day commitment if I wanna get paid....

venture restriction
venture restriction
Damn, Everbody take a chill pill, drink a beer, take a nap, whatever. I've done everthing that's been posted on this thread so far for my nw200 and so far it's obvious to me that it works. So I don't need pictures, and I don't have a camera so I won't be posting any pictures.
Rich or Rowland, How or what are you doing to restrict the venture to get more air the skimmer. It's pretty obvious it's producing plenty of gph now. because with gate valve wide open it still overflows. So I guess now I need to get more air to it to slow down the gph. Wants I know how to do this there's no doubt this thing will kick some serious ***!!! Pretty danm good for a $200 skimmer. I'm very impressed!!! Thanks for all info on this thread.
Sorry about above but come on, give it a break!!
Thanks, Robert
