Dosing Pump Units - Which One?

What I like about the new GHL Doser is what it can do. It can dose .1ml, Level Port, Temp Port so it's like a mini controller, plus you can add stirrers to it. I also like the software for it. You even have a alarm on it when fluids get low. That's pretty cool.

One thing about the apex it's a two pump. Most ppl dose the Cal, Alk and Mg, so you can only do two part. I like three part and a 4 pump to dose whatever I want. Right now, I dose the NOPOX.

The Kore 5th can do all that and more. They even have a standalone kit with two bigger DC-pumps for AWC if you want to change more water then what's possible with the stepper motors.

I first had a Jebao DP4 and that worked OK but the unit was a pain in the a** to constantly change the dosings for three channels (Balling) and the calibration drifted a little over just four weeks.

The Kore 5th is really premium and the software is great. They are very active on the forum and constantly listens to the customers for ideas and so on.
It has for example the possibility to dose 144 times/24h on one dosing motor and up to 24 on the others. Down to 0.1ml/dose and a specifik drop dose kit. Magnetic stirrers, temperature sensor, ATO, low liquid level alarms, liquid left,

With the 20% sale right now it's only 359$ right now, 431$ for the pro (better tubing and optic sensor for ATO) or for 550$ you get it all. Pro, AWC DC-kit, Drop dose dispenser, bottle tray and acrylic holder.

If you hadn't figured it out yet, I LOVE my unit ;).
 
Well Kore 5th has 5 dosers, ATO and AWC all-in-one. Can also add magnetic stirrers if needed.

Just for clarity so everyone has the right info on all units, the GHL Wifi Doser 2 comes with built in ATO AWC plus Temp, can in the future have any PAB device GHL makes connected to it, for example the possibility of power bars?. It also can be expanded up to 16 pumps, comes in a non rusting case. You can have just 1 pump if you really wanted.

German engineered and built
1-16 stepper motor pumps
ATO+AWC
Temp port
PAB port for future PAB device connections (Profilux Address Bus)
It also has 4 ports for stirrers.
WIFI Built in and USB port
port for future independent touch screen option
German built stepper motor driven
doses down to .01ml
plus 2 year warranty.
All APPS plus cloud based, and software
As GHL Doser 2 is Wifi built in it does not need the added expense of a bridge to get online. So when looking at the price points always take this sort of thing into account
It does not need a controller to run it either. The controller is your smart phone/device or computer

Just wanted to add for clarity so the whole debate is even and correct info shared.

Litermeter 3 is a great solution too. You can add up to 3 slave pumps for a total of 4 pumps. It's easily calibrate-able to insure accuracy and can be programmed to dose as much as you want. What ever you set it to will be divided up over the course of a 24 hour period to insure slow dosing.

Set it and forget it. No fancy programming or additional functions, plain, accurate and reliable.
 
Very nice. Never knew that. I thought it was merely a doser. So that level port can be split like Profilux unit?

yes, that is right.

Also the PAB port possibly "could" in my view make it a bit more than a doser (although of course this is hearsay) as GHL directly said "with the PAB port expansion is limitless" Reef-Builders had their own take on this which GHL have not commented further, so for now its a Digital Wifi doser with a very intriguing future!

I see that it started to be an advertisment thread, so to be honest with all above I want to clarify some important points about Kore 5th doser because some of above information's looks like little intentional misrepresentation by comparing the possibilities , but maybe I'm wrong :)
I think that we can compare GHL Doser 2 with Kore 5th PRO because they have similar prices(GHL - 559,00 USD, Kore - 539,00 USD)

1. Kore 5th is completly built and designed in Poland
2. Kore 5th have 5 very precise peristaltic pumps and doser can be expanded up to next 4 pcs pumps - total 9. I cant imagine any setup which will need more a specially that doser can do water changes(AWC) and ATO(refill) by included in set DC pumps. Using included DC pump for ATO give us still possibility using all 5 peristaltic pumps.
If for ATO is used dosing pump - from original 4 pumps left only 3(so sure, slave can be needed). Additionally, if doser use peristaltil pumps for AWC+ATO work only one dosing pump left for Customer. I think its VERY important information.
3. Kore have ATO+AWC funcionality not only built in - but also offer it from the beginning because this set include all needed equipment - like 2pcs floating level sensors(up/bottom level) and one optical sensor. Can ATO or AWC work(precisly) without level sensors? Thats why Kore 5th include this sensors in set(without additional cost). This three level sensors can be connected to doser in the same time(can be configured as main ATO sensors, bottom/up level sensors, high water alarm sensors etc).
4. Kore include digitial temp sensor in price and it can monitor aquarium temperature(turning on/off sound alarm if its needed). This temp sensor is include in set.
5. Kore 5th have digital input/output port for ANY future expension kits(like pH monitoring, relays,heater/aquarium cooler etc. First device which can be connected to this port is Magnetic Stirrer which was presented here:
http://www.advancedaquarist.com/blog/pacific-suns-kore-5th-magnetic-stirrer
and will be available since January 2015. MSRP = 99,00 euro.
All other modules/features are already in development - like special cooled container for dosing corals food(with auto emptying tubings from liquid after dose).
So limitations in the development are also limited only by the imagination ;)
6. Kore work in Bluetooth communication layer, but IF anybody will want to use it by internet(?) its possible to connect it via incoming Cube wireless bridge(BT<>Wifi).
7. Kore 5th resolution is 0.01ml which can be achieved using best quality Japanese DC motors. On this movie it's shown how precise they are(single dose 0.01ml - doser need three doses to "built" single drop):
http://www.advancedaquarist.com/blo...e-5th-dosing-pump-with-new-dropdose-dispenser
If GHL Doser 2 can work with the same resolution its very good and enough for aquatic industry(previously they shared info thats resolution is 0.1ml).
8. Two years of warranty and 5 years warranty for non-rusting cover(because its made from ferromagnetic stainless steel with powder coated layer).

Finally I have to agree with Michael:
"So when looking at the price points always take this sort of thing into account".
Both dosers have their own cons and pros a specially if we will compare what Customer can get "in package" together with doser(like all level/remp and for what he have to pay to be able use advertised funcionality.
GHL is proven and good known company but we see some actions which are atrying to depreciate our product(quality or included options).
I think that time will tell all, lets users rate this product.

"Just wanted to add for clarity so the whole debate is even and correct info shared."

Like always I really appreciate discuss with Michael from AquaDigital :-)
Thank you.

Best regards

Currently the GHL is
Flow rate adjustable: up to 45 ml/minute
Dosing volume adjusted to 0,1 ml

GHL said to me prior to Macna the intentions is to increase the flow rate once everything is released and there will be an option for a high flow stepper motor pump.
 
Kore 5th PRO include three different tubings, pumps can work on three different speed(fast,moderate and precise flow).

Depending on the tubing used, you have the option to achieve the following performance:
a)high flow Pharmed/Viton/Santoprene
Fast flow - maximum average flow 110ml/min
Moderate flow - maximum average flow 60ml/min
Precise flow - not suggested(inregular flow depending from material hardness). The best for precise dose is silicone tubing.
b) high flow special silicone tube (thick)
Fast flow - maximum average flow 140ml/min
Moderate flow - maximum average flow 110ml/min
Precise flow - maximum average flow 50ml/min
c) precise flow special silicone tube (thin)
Fast flow - maximum average flow 60ml/min
Moderate flow - maximum average flow 26ml/min
Precise flow - maximum average flow 10ml/min

So answer is - flow for dosing pumps can be set between 10ml to 140ml/min.
For DC refill/AWC pumps - they have adjustable speed(from 30% to 100% and average measured flow in tubings included in set(5mm/7mm - ID/OD) is between 30-90 liters per hour.

No other pump has the long history of durability and reliability of the LiterMeter.

I've run litermeters for 8+years with only occasionally changing the pump tubing and cleaning the pump heads. They are as reliable as anything in this hobby
 
More questions for both GHL and PS....

Can any of the pumps in either doser work continuously, like for a calcium reactor?
If not, what are the recommended max run times before the plastic rollers get too hot and start to wear down?
How many times per day can the pumps be run?

GHL... I see there is a slave unit coming out soon. Is there pricing for this yet (USD) and what differences are there between it and the SA?
 
Yes either device will work for calcium reactor. But if you are spending this money on a doser why use a calcium reactor? your system would benefit from classic balling such as Hans-werner balling system from Tropic Marin.

For pricing on products please visit the relevant sponsored forum. As PS said this should not become an advertising thread, info only, if someone asks a questions we both can answer it but when it comes to pricing where to buy etc etc this should be kept to sponsored areas. It would be good also to see other dosing companies post their product info also at this point.

The slave launches I think January, details to follow then on the advanced capabilities.

I'm currently researching peristaltic pumps to run my CaRx, ATO and AWC.
I have no interest in dosing liquid alk, calc, mag. And I already have the previous GHL slave doser.
I could go with separate pumps, but if these new breed of dosers can handle it the workload, I like the idea of having a single unit for just a little bit more $. That's my priority. Secondarily, I may dose aminos or something else.

When i first got my GHL system over 2 years ago with the old doser, I tried using the doser for AWC and it failed for two reasons.
1. The doser could only run something like 12x per day? Whatever it was quite a bit less than I needed.
2. Because of the above, it had to run more than 15 minutes at a time which was causing the rollers to break down quickly.

But it is looking like these issues may have been rectified?
And how many times per day can it run?
 
Peri pumps are not designed for large loads, this is why the modern dosers will come with options to use larger pumps.

As you have specific sales questions maybe best carry on this chat over email info@ghlna.com that way we can discuss more directly your needs without this very wrongly turning into a sale thread which would ruin it.
 
its is but you are asking about price etc, I "personally" would rather not get involved in that on open forums we will release these details (which are already released) on our sponsored area. Its so we stay within and respect RC's important rules.
