automatic water change

SpectraPure said:
Eddie you sure are a trooper! I commend your valor! LoL This Dos sounds pretty good. I was suggesting that we add a graduated cylinder to our build about a year ago. Also I hope these pumps work out for you long term. If you find that they do not our pump assembly can be installed into their set up. While they will tell you not to. If you find that those pumps are not reliable, there is an option for you Dos Apex users to integrate our proven reliable pump into their setup. I do imagine that it would negate the warranty.

It seems that the first competitor to have a calibrating function only took a decade. Does anyone else have the problem that you don't know if your Liter Meter 3 is on because of how annoyingly quiet it is? Such a pain...have a good weekend everyone, and if anyone has any technical questions of any kind please let me know.

Also I have designed a direct ATO for people who cannot have a separate reservoir out side of their sump, but who do have room to mount a rectangular reservoir above there sump.

I also am curious what the flow rate is on those Dos pumps?

How high they can pump?

Can they pump accurately if one line goes up 6 feet, and the other line travels on a level path, or even a downward path?

What is the minimum and maximum amounts it can pump accurately?

Also when and how long the tubing lasts when the first person has to replace it?

For anyone who has asked me for the deal from before the offer still stands. Also Liter Meters are 10X reward points right now. That is a total of 26.99 in reward points, free shipping, and I will throw in a 500ml bag of phosphate media removal, and a 500 ml bag of carbon for your reactors.

Good night Florida!

Let me know if any schools or projects you have are coming up. I am always very happy to donate to your proactive club!

I did not realize that these were stepper motors. Our pumps and motors will not integrate with their system.

Nah, they can pump in either direction based on your need. Some people have been using them to dose foods and then clearing the line.

To answer some of your other questions, the DoS goes from about 7ml per min to 250ml. The motor is a stepper motor, similar to what's used in 3D printing, rated for about a 33% duty cycle. I'm not aware of anyone replacing the tubes yet, but it's super easy to change them out. Neptune is claiming somewhere around 2500 gallon life I believe, varying somewhat with how fast it's dosing.

They also claim a 0.1 ml minimum dose. Mine is currently pulling about ten feet vertical and 60 feet lateral. I think they tested to about a 30 foot vertical, push or pull. After calibrating with short runs, I tested the long run and it was still accurate.

Oh then they have it like our UPLC-II. That is our ATO that can be used as a sump pump as well.

I have a video next week that I will share!

I wanted to keep it well above the salt water container and out of the way of my dive BC rack thus the mounting position.
My lines travel a total of about 50ft (40ft across or so with an 8 ft height down to the sump or 5ft drop to drain) so far my calibration run was equal on both pumps at the end of either line (sump and drain).

I like the ease of use with the apex integration, just log into fusion - select the water change wizard - and tell it how many gals to change over what period of time. Maybe i can screenshot the wizard.

Okay here is a shot of the screen where you set or modify the intervals (you can add or remove water which in turn runs pump forward or backwards).

This next is a shot comparing both pump programs with each other (one shows add the other removing the amount of water in ml

And the last shot shows the graphical log of what has run through the pumps in last day (you can access detailed log within that one)

Is it possible to run a similar setup off of the controller not using Fusion?

Call me paranoid, but I just don't like my tank being one login away from being controlled by somebody on Fusion.

I guess you could set it up on Fusion, then lock fusion control on the controller after the setup is done?!?!
 
You don't have to run fusion as far as I know you can still run the APEX the old method. IN fact many things still have to be done that way or did. Each update to fusion they are making it to where you don't have to use the old style to make changes.
 
This is correct! I had to calibrate using the control screen as they have not added this function to Fusion.

You setup your own username and password and you can add users with view only capabilities to be able to access and only view your apex without being able to make changes.

It's possible, but the wizards don't exist in the standard web control.

It's pretty simple to set up, you just have to create some profiles. You do lose the visual representation of the dosing as well.

I wish they would just bring the Fusion interface to the local network interface and not force you to use the remote version.

Totally agree...

I've been a software architect for over a decade and HATE "the cloud". I'll keep all my stuff local :)
 
I would imagine it would be the same thing
Not sure how reefkeeper works but in apex you just program the outlet to turn on/off whenever you want and for the pre determined time you program and the stenner changes a certain amount of water out through both its heads.

Thanks for the relply. That is what I assumed I've read through this thread and the mention of the stenner pumps being compatable with apex controllers lead me to believe I was missing something.

Anyhow my stenner pump is onits way which was ordered through their site yesterday. Mind you there was a charge for shipping there is mention of free shipping apparently that has changed. Total with tax n ship was 322.03.

So what would be the difference running the stenner pump with a RKE versus an apex controller?
Click to expand...

I agree with Zaffor- there shouldent be any difference. All you have to do is fiqure volume/time (preferable minutes), and you have your controller turn on and off depending on volume you want to change, it can even be done with a regular home improvement timer.

Safety switches should also be the same if the RKL can control float switches.
 
I should have listed mine earlier, i had purchased a stenner to try out before I bought the DOS.

Also according to your sig you have an Elos 120xl ... Still own it?
 
Yes I still have it. Was considering selling it and ended up starting over im glad it didnt sell. Now i have a decent collection of fish and its coming around. Maybe once I get it setup how I want and prove to myself I am going to keep it up ill get some coral. When my stenner pump arrives ill refine my mixing station and take it from there.
 
Love the elos still has a little wow factor even as fish only

The controller is a reef keeper elite no bragging rites around here

Here is a short video of the DOS operating at mac speed. Im giessing that if you spread the water change over several hours it might run slower and quieter, but I wanted it to run over a shorter period to keep an eye on it.

Its definately not quiet but not bothersome with the door of the closet shut. My salt container mixing pump runs during the same time.

Hi Zaffor

Thanks for posting this video, as I have been wanting to actually hear how loud the DOS unit performs AWC.

Have you prolonged the duration of water change intervals and has the DOS became less noisy? If you have another video with it running at a medium or lower speed, I would be very interested to hear how loud it is.

I would be primarily interested in the noise that it makes when performing 2.5-3 gallon water changes over an 8 vs 24 hour period.

I really like the Apex integration of the DOS, but the added noise could be a deal breaker for me.
