You'll really need to get a kill-a-watt to even know wether you need to trim the mesh back. How do you figure you need to lower the watts if you don't know what they are?

I've been messing around with a Gen-x 4100 on my DNW-200, and I have to say that it has potential if you're running it externally (no rust). The best I've been able to get is around 30 SCFH, but others have gotten even better results. What I like the best about it, is that it moves less water to get these numbers = less turbulance. The down side is that they may be a bit noisier, and the mods have to be perfectly executed to see the improvement.
I still love the OTP-3000 for doing the mods, b/c of the larger volute, and the head room for improvements that can be had. The Gen-x has some head room for mods, but not like the OTP-3000. We can't forget though, that we are overdriving these pumps and these factors will contribute to over heating and shorter pump life not to mention that it'll be much more prevelent during the summer time. I'm on my second pump, b/c the first one started to decrease in output after about 3 months of use, and I couldn't get above 25 SCFH. |

Dont end up like me when modding though!
While all is well now, I got a little over-zealous and said to my self..."self, that still looks a bit too small" Stupid me. As you can see from the yummy pictures and the short time frame it appears to be working fairly well after some Macgyver skills.

I'm still leaning tioeard the ER Sedra 3500 as the replacement pump. I can put it on the skimmer and not have to mod the pump at all and it'l skim well. I'm saving the DIY skills for the big skimmer I'm working on

If you're modding them properly, and using a killawatt and a flowmeter, it will be pulling SIGNIFICANTLY LESS WATTAGE. Quote:

THe DNW110 it is going on can only handle about 14-15 SCFH even with the 18" neck extension. Maybe I could mod the venturi and get close to that. I'm just sick of the OTP pumps burning out on me and want to get a pump that will do 8-10 LPM and be reliable...pref not chinese junk. Any other suggestions Rich??

I thought the octo was the best thing out there? Now all of a sudden these pumps/skimmers suck (or not)? I've read 80+ pages of how to do some simple mods to these skimmers which was supposed to make them equal to others 3X the price. Now that suddenly has changed? Whats going on?
For what it is worth. I'm pretty happy with my NW200. Did the mesh mod and opened the venturi a bit-- and I'm pulling out some nasty funk. |

Octopus redesigned the pump, less windings and a smaller needle wheel is my understanding from what I have read on here. A few simple mods to mine, after the breakage and repair, it is brand new and I have to have the standpipe all the way down or the foam is literally push the top off. The bubbles are extremely fine in it. I am waiting for my kill a watt to arrive to see what it going on with it before I get any more extreme.
Maybe a video of the bubbles in the canister for all to see is in order?

i know that it's hard to change somthing that you dont know what your changing from but, i figured if i can just trim it back.. to even use a little less electric then cool... im really poor... so i rather not spend more money then i have ( i know a lot of your are in the same boat) plus i think it's pulling too much air for the neck size... im still using the OG valve on it and i cant 'fine' tune it to exactly where i want it... it's always a little too wet (green tea) or really dry (2 weeks to fill)... the problem is that the neck gets too crudded up when it's too dry and it take forever to skimm stuff out... i clean the cup 1x a week... just to keep the neck clean but i just would like to not have to sqush my hand around in all that just for 5 minutes ...

Where do you get air flow meters from to measure how much air you are pulling?

There will always be better pumps, and there will always be cheaper pumps...the hope is to find the one that is best for the money, and I just can't say tyhat the octopus pumps are that pump. FWIW, I'm going to keep the octo body and just mount a new pump on it.

I tried to obtain one locally on the CMAS forum but no one appears to have one. I really dont want to buy it for the couple times I am going to use it.

When was it that the octopus skimmers got the cheaper pumps? I bought one on Nov 2006. I know that you can measure the needle wheel but the problem is that i had received mine with a regular paddle wheel and then the online store sent me the regular needlewheel.

alright, played with mine a little more. started the day with 15scfh @ 55w.
ported the volute, played with the venturi a bit and added a 3rd layer of pf4. still can't get better than 17scfh @ 90w. i'm reading at the middle of the ball btw, if that's wrong speak up.. that's hotter than i want to continually push this pump. i have a new venturi otw (want to try one more thing) and if that doesn't work, i'm definitely gonna look for a new pump.. |

Wow, they've really screwed up their new pumps!! Does any one have one of the new OTP3000's they'd be willing to ship me just to see IF they are really as bad as they sound? I could mod it and ship it back after testing.
Porthios, middle of the ball is where I read mine at. what meter do you have? If it is one of the RMA's they can be a little restrictive, due to their small fittings...but you'll only lose a few SCFH even then. 90 watts will quickly burn out the pump. What is the PF? ibmgeek...You should have one of the good pumps! A little modding and you'll be able to tell pretty quick.
