is it worth while to change to abyzz from vectra ?

[David Cher]

i am currently running 100% of the vectra m1 on my 4x2.5x2ft tank . should i just change to L1 or just get abyzz?

Is the flow insufficient? What's your reason for changing?

 

[David Cher]

i find the turn over might not be sufficient and my vectra is making the dc motor humming sound .

You should need about 600-700 GPH for a 150 gallon tank.

From Ecotech's M1 info:

Unless your sump is in your neighbor's basement, it seems like your current pump should do it.

Seems like even the S1 should be able to do that.

A $100 QuietOne 5000 that comes with a 3 year warranty would do it. Same for a $100 Mag 9.5 that comes with a 5 year warranty.

Tell us more about the plumbing you have on the return and let us know anything else that's relevant to the idea too!

Check your installation to make sure that isn't the cause of the humming.

Otherwise contact support or your retailer asap before warranty runs out.

What is your plumbing diameter leaving the M1? I have my M1 going into 3/4” pvc and if I turn it up past 50% I start hearing the pump hum. If you increase the diameter of the plumbing it will significantly reduce head pressure and allow you to pump more water with less noise/vibration.

Whether it is worth changing to the abyzz is really entirely up to you. I cannot imagine a scenario where I would pay that kind of money for a return pump; but clearly some folks do. I run my M1 with native 1 1/4" out and it is absolutely silent.

The pump you are using should be fine.......a lot of people try to push too much water through the sump anyways. I would use your powerheads for waterflow rather than your return pump.

the other reason being i am running a chiller and needed to maximum the return of the chilled water from the sump to the return

The chiller has a recommended flow through it for maximum efficiency. Running more water through it isn't going to give you more chilled water.
In fact I would think it would be opposite.
Stick with the recommended flow through the chiller.
Figuring out all the head loss with a chiller added in seems like a pain. But I'm sure someone here could do it.
I like to run a chiller with a dedicated pump.

What's the recommended flow rate through the cooler for maximum efficiency? Have you considered or do you have an Apex flow meter for the plumbing through the chiller to make sure you're getting that flow rate?

 

[ca1ore]

My experience is that you want to stay well above the minimum flow level - otherwise the chiller either short cycles or freezes up. The max seems more a function if what the native plumbing can reasonably handle. I cannot see that it would affect chilling efficiency.

Did you calibrate it when you set it up? Maybe it needs to be cleaned? I run my M1 @ 70% on my 90g, but I'm running Triton, so I need the turnover, but it's still pretty quiet.

I wanted a vectra and read too many stories of issues and my sump is in my basement so I went with the abyzz a100 it runs at 80% with 20 times tank turn over in an hour and feeds my reactor. I couldn’t take a chance on the heart of my system.

+1... I use an Abyzz for a basement return.

The initial cost is high, but Abyzz pumps come with a 10-year warranty. My tank uses a pair of L1's for closed loops. They can not run at 100% without overheating; despite EcoTech's promises to the contrary when they were released, they are not controllable through my APEX (so no tidal effects); they are prone to calcium buildup; and after 18 months I just had to replace the first one where the impeller swelled and locked up.

Touch wood, I have had zero problems with the Abyzz in that time. If not for existing plumbing both L1's would have been replaced long ago with smaller pumps from them.

If you can play the long game and put the cash down upfront, I maintain the Abyzz pumps are one of the best values I have experienced in 40+ years of keeping aquariums.
