ITS FINALLY HERE!!!!!!!!!!!!

Check out Mark Callahans review of the GHL dosing systems

http://www.mrsaltwatertank.com/main/

The review coincides with the large price drop in the GHL dosers bringing them more in line with todays market with no reduction in quality (of course )

Please feel free to spread the word lets get this viral!!

Great review, quick question, in the review for the stand alone he mentioned not having to do the math, just put in the number of ML desired and the number of times. How do you that when using it with the profilux?

I have been doing the math to say X amount each time and X number of times.

 

[AQD_ottawa]

This is correct, he is basically saying once you have set that up the unit will do the maths to meet your required daily dose.

Basically there are two ways to skin this cat

1. Tell doser you want for example 60ml a day and the doser will auto dose that over a split amount of time
2. As the GHL does it in auto mode, tell the doser you want 10ml 6 times a day

With option 2 you have control of deciding how you want the 60ml spilt, option 1 leaves you with no input.

The User friendly and mpre precise option is option 2.

I now dose 6ml X 23 Times a day (138ml) , if I want to increase it to 140 or any number less than 144 I've got make fairly large doses (10 * 14).

I would much rather the doser take my requirement and divide it by 24.

All that being said, can you do option number 1 via the profilux?

 

[AQD_ottawa]

not yet

 

[AQD_ottawa]

Hmmm wait a minute

You want the doser to divide you dose by 24 well is that not the same as multiplying it so for 140ml over 24 dosers is rounded up to 6ml so 6ml x24

You are just skinning the cat in reverse

Basically you are asking for the doser not to force you to do a maths calculation. I think there comes a time when its nice to have some input into what we do with our equipment.

Dont get me wrong in the language I am using to explain this, its not a dig, just highlighting two things. Firstly the GHL already pretty much does this just multiplies and secondly all GHL is asking you to do is know how many doses go into your required dosing amount.

As I said two ways to skin a cat still acheiving the same goal.

I regards not meeting your exact dose rate of 5.83ml x 24 to get 140ml, no doser can dose in sub 1ml increments so even your method will end up with an averaged round up dose.

Profilux is the only company that provides a controller with matching doser and this was the primary reason for my choice in using Profilux to control my system. For anyone that chooses to dose over using a Ca reactor, a dosing system is a strong consideration and in my case a necessity as I travel frequently. I haven't had any problems with my dosing unit and it does the job that I need it to.

 

[this is me]

If you think the standalone doser can do more than the slave doser w/Profilux, you're not using your profilux to the full potential!!!
With programmable logic gates, you can dose any way you want and for how many times you want.
Let me know what you are trying to achieve. I can come up with the setting on the profilux to do that.

Thank you for the great comment, its always nice to hear from users and why they love the brand.

Feel free to export your comment to the review on Mr salty TV

Yeah that's a true statement, I only use the profilux to control the GHL doser and as a back up for another system.



Some of my other dosers allow me to key in the number of ML per day and take care of the math automatically, it appears the standalone unit can do that, i noticed that in the video.

I simply asked if you can do the same logic with profilux as you can with the GHL standalone , the answer apparently is no.

You can skin the cat two ways with the standalone but only one way when controller by the Profilux.

If that's the answer, no big deal...

I'm confused the GHL standalone doser does exactly what I'm talking about, are you saying it shouldn't?

So you only want to input the amount of liquid being dosed into the tank? How do you know that the system is not dosing all the liquid at once? What if that 140ml of liquid you're dosing is being dosed all at once. Or twice at 70ml? It's an easy and lazy way. But you don't really know what the hell it's doing. And that is scary.

It's like asking your GPS to get you to your destination. If it doesn't have settings for which road you prefer, you can be in traffic for hours on the local roads.

The controller allows you to input the amount of liquid AND how many time you want it so that you can get the PRECISE amount into the tank. Think about it a little. Automation is good. But it's only good if it allows for multiple inputs.

Nick the GHL standalone doser takes the total amount entered and divides it equally across however many of increments it can handle. (it's not going to be less than 24!) 140 / 24 = 5.8 (yes rounding) or it might actually do 23 X 6 and then 2ml on the last dosing for the day.

In all likely hood it's more increments than you can program via the profilux, example the Litermeter doses across 150 increments a day, I suspect the GHL dose has something similar.

The GHL doser (via the profiluX) limits you to once an hour, that's not very flexible. My assumption is that is GUI issue rather than a limitation of the dosing pump.

Eitherway, dosing 24 times a day is better than me dosing 14ml X 10 times a day.The other option is to dose less, or more?

Nick, does this better explain why I'm looking for this feature?

 

[this is me]

You can dose every minute if you want to in the Profilux. I'm not trying to defend the Profilux to death but your thinking of the limited capability of the Profilux is wrong.

Your LiterMeter can do 1500 times a day?
Try cyclic function on the profilux. How about turning on every 1s? How many points is that in a day.

Again, you don't know what's the system is programmed to do without being able to input this yourself.

Er Hum moving on to something for me important

Can you all please post here your thoughts and feeling of the GHL doser

http://www.mrsaltwatertank.com/the-ghl-stand-alone-doser-reviewed/comment-page-1/#comment-3814

For our review to be a success it is important real users pass on their own impressions.

 

[reefkeeps]

LOL,, I should key in 1500 lines every time I up the dose... That's a lot easier than having the controller doing the math, be real. If it's such a horrible idea why did GHL add it to the standalone?

I don't know why you are defending anything, it was a yes or no question. Does the profilix have the same automation option, the answer is no.

 

[AQD_ottawa]

Ok do me a favour tell me what functions you want adding to -

slave doser modes
Stand alone doser modes

I will do my best to convince GHL to implement them, please take into account changes are easier to make for the slave than the SA and also be aware the slave will always have more functionality than the SA.

Now how about adding some positive weight to the review?

 

[reefkeeps]

My suggestions for the Slave,


Automated precise dosing

The ability to insert a number and have the profilux dose it across a 144 or more equal dosing


Better Calibration mode

Make it set to dose 100ml, you then insert the amount it actually dosed.

You clearly don't understand the flexibility of the salve doser. :deadhorse:
I'll stop here to avoid anymore nonsense.
