19 dosers on a GHL system.

[forestsofkelp]

Hi, I am planning a large tank, and looking to do DSR method, with a full GHL set up, and as many things on dosers as possible.My current plan uses 19 dosers, and I am a little worried about the 16 doser limit. I was wondering if anyone could give advice or know a way to get around it, or if what I am thinking is even possible. Right now, the best I am thing of is the following 3 "sets" of pumps. I have not used GHL before (or any controller) so pardon me if my understanding/phrasing is wrong

1: KH director with 3 pumps slaved displaying the KH value on GHL control center with all my other data.
2.: ION Director displaying the Ca and Mg values on GHL control center, with all my other data
3. A ProfiLux with the following pumps that I manage, using data from testing and the ION/KH directors: Alk, Ca, Mg, K, Strontium, Boron, iodide, Manganese, Fe, carbon, Aminos, ATO and a concentrated NaCl solution (to adjust salinity for fluid loss during testing). Thats 13 pumps. I'd use an additional 3 pumps for a Tank-Phyto-Rotifer-Tank drip feed.

I assume I can move control of the the Ca, Alk, and Mg drips to the Directors if I want to, but I cannot move Director drips control to the Profilux because then I would be over the limit. However, if I made the drip feed system and NaCl a standalone, I would have room for 4 drips and could have the Directors be under Profilux control (3 pumps for KH Director and 1 for ION). Is that correct? Thanks! I can't wait to get my set (the waiting is killing me)

Right now you can only have 16 dosing channels but they are increasing it in preparation for the Ion .

At reefaplooza I was talking to them about this exact issue, and was able to show them what my configuration was and how I could not use the Ion because of it.

You could always use the khd with a stand alone doser to reduce that load until they get the update for more dosers.

Yes a stand-alone would allow you another 16 dosers.
I think the 16 doser limit can be changed.
With the standalone and the GHL connect app it would be easy to control many dosers. That is how I have it setup. A SA and Profilux control equal amounts of dosers.

Hello im having same question, and waiting for ghl frimware upgrade. They must do it we need moore dossers for GHD and ions...
Your solution KHD with SA dosser is nice but can you tell me about some questios?

1- can you see kh mesurent at ghl app in ur smartphone same time you see the redox , ph, etc ? I wanna see all measurements and dossers in same screen. Just take a look no switching devices...
2- i use profilux 4 control ph for calcium reactor. Can you control profilux ph with a KHD + SA??
3- any new about ghl frimware upgrade to 24 or 32 dossing pumps???
thanks

1. Yes, all can be seen on the same screen in the App.
2. Not sure, but I don’t think so.
3. New firmware is coming. With the release of the ION director allot of new things are coming to include the Doser limit increase.

1. If all the devices are connected via a PAB cable and are configured as slaves yes. But if you have for example a P4 and my KH is a stand alone not connected to the P4 I would not see for
Example KH value while loged into the P4 unless I used the log book and recorded the values of the KH manually.
2. You would need to switch devices. You log onto each device through the app.
3. Firmware is on the way to have us increase the amount of dosers connected to the P4 and is part of the ION release.

I am not sure why you are dosing all of these chemicals individually. You can already buy supplements that have several of them combined in the correct proportion. That would eliminate almost half the pumps you plan on using and it is much easier to get it right and to maintain. You can always test the individual elements and add some by hand if things are not balance at the start. If they keep going out of balance you can add more of an element to the supplement mix to tailor the mixture to your tank.

It just seems like your doing more work than you need to.

Thanks for ur answers....

well as is confirmated and frimware upgrade that allows 32 dosser pumps... i will buy slaves and all conectes to P4.

about aditives... may be another products just in one - two Pumps... colors is with 4
