Cor 20 Cor 15 Pump from Neptune

Thanks for the post. 1.5 years is a little over the warranty which is not a very long time. Even Eheim offers 3 years. Currently using a danner mag drive 19 and this thing is a old beast. Just because its all I had on hand after the vectra went to ****

Correct. 1.5 years isn't a long time. However, it is also about how long they have been on market general availability vs. beta. So in the grand scheme of things that is a pretty good track record at least in my case. Just providing my experience and if you haven't you could always swing on over to the Neptune forums and see what other users are doing good or bad.

I've also had good success with Mag pumps. I used to run a 9 on my skimmer it worked great. I only discontinued its use because I wanted to run a DC pump. I use it for water changes now. Before that I used to run an Iwaki on the skimmer. Only reason why that still isn't in service is because while on vacation and a series of back to back brown outs in California and Enron my AC tripped a breaker, family and extended family are all together so no tank sitter, and evaporation was quick, refill / top off is gone, pump died due to heat, no water, etc. Great pumps Iwaki are though but again that was a while ago and I wanted DC pumps now.

29 gallon bio cubes, not what you are look for in regards to flow I had Rio's. Those also worked well. Not knocking other pumps but I do think you get what you pay for. Vectra's did have issues but those are resolved I believe and they stood by their product. Support is key in this hobby so those are a good choice if you choose them. I've had overall good experiences with Neptune support going as far back as 2000 - 2001 with their original Neptune and X10 relays.

Whatever you do don't buy a pump just on my info but I did want to say that mine are running very well and I'm happy. Check out the Neptune forums, read up a bit on the new Vectra's, and maybe start there. Then expand your net and see what makes sense. Regardless of what you end up with I would recommend having a primary and secondary for redundancy. If not use the same pump on your skimmer to swap out in case of an emergency. If you can use the same plumbing. If not then plan for a spare offline. Return pumps are one of the heart beats in our system.

No return = failed tank if we don't catch it in time. Best of luck whatever you choose!

Quick question here: if apex stopped working or had to be changed for any reason would cor still work?

The COR-20 can since it can be used without an Apex, but the COR-15 requires an Apex.

I think I might just get a royal exclusive

titianium rotor and the bypass so it dosent clog or calcify at half the price of a abyzz

I have this on my skimmer and I have another RD 80 on my return.
Red dragon is a beast and the best in market along with abyzz..if you compare build quality its day and night...day and night.
And am not talking about the plastic wrapper...plastic of apump do not describe the pump performance am talking about cire pump part..all german engineering done in house.
Other lower grade pumps all have the same cheap core parts imported from china...

As I said, skimmer, return pump and power heads. I cannot get any of these dependent on a conteoller...these are the core of any aquaroum system.
I buy equipment from companies where their core buissness is that part. Otherwise it's very cheap to buy something from china and put a logo on it, which is what most lower grade pump vendors do..
That's my honest openion..

Depends what had the problem. Cor 15 gets power via the 1-link. So if the 1-link power source failed then the return pump wouldn't get power and thus be offline. The Cor 20 has its own power supply so would not have this happen.

The idea behind the 1-link (not speaking for Neptune, this is just my observation) is that it only needed so many Watts, 50 I think) for the Cor 15 and by using the 1-link it would save you a outlet on their power bar. Cor 20 flows more so needed its own power source.

Thanks for the info what happen if 1link disconnected from apex..physically I mean?

I'm probably going to get this wrong because I'm at work but the easy way to answer this is that it shouldn't disconnect on accident unless it isn't fully plugged in. It is a cable that only has 2 pins and there is a clip on the outside of it that connects to the receiving end. So it is secure if that makes sense.

The energy bar for example has three 1 links. Then if you add other modules there are 1 links on them usually. It is their common link tech I guess. Kessil is using the USB C connector for example to send information. Think of it like that I guess. I'm trying to say it won't, or shouldn't, come loose or disconnect under normal circumstances due to how it is made and the clip.

Also note - I'm not sure if it is wise to put everything into a single ecosystem regardless of the brand. This thread was about the Cor return pumps and I believe they are good products. However, as I answer a few follow up questions from @Ohashimz with regards to the cable, 1-link, etc it does raise a interesting point. If a power failure happened and you didn't have a backup then you could lose more that make up the end to end life support of said ecosystem. This is not bashing Neptune or Apex just saying this is also something to consider.

I have a Cor 20 and Cor 15 so will not see the complete outage because the Cor 20 is plugged into a different outlet for this reason. However, I did want to come back and suggest has a hobby member that while great pumps please look at your end to end system to make sure you have fail safes in place regardless of who you use.

Ok so am gonna go ahead and bet that you do not have enough flow rate.
Your volume is around 170g. The recomended return flow should be between 850gph to 1700gph.
My recommendation is to increase your flow and adjust your overflow system.
If I have to guess I would say you are at 200 250pgh now which is way too slow and reduce the efficiency of any filtration you have in the sump.
I dealt with this in the past and I was chasing my tail until I measured my vectra flow at that time and discovered I was having slow flow rate. Once I improved it my skimmer was working incredibly better and my nutrients improved alot..
My 2 cents

Thanks for the feedback, you've certainly got me thinking. However, at 40% I think the pump is generating way more than 40% of it's total capacity. In other words, if you're running at 1%, it's not actually 1%. Can anyone confirm this with a flow meter?

I hope you right, though if you are it will make no sense. Whem.i had vectra 1% meant very very low flow that was almost 1%. Am really concerned about your flow. How about you ask Neptune what's the expected flow reduction percentage at 40% power.
We know at 75%~100%power flow rate is 400g on typical head pressure( from earlier feedbacks) this way you can calculate where you at, otherwise you can always use a flow meter to measure.
Anyway good luck sir.

 

[road_runner]

Another way you can measure how long it take to fill a gallon container from the return end point.
From there you can calculate what's your gph.
Say if you filled 1g withen 1min Your flow is 60gph....and so on
