This is interesting in my case compared with Rick.

Hanna measurement is more or less same as Salifert (Hanna ; 7.3 and Salifert 7.3 -7.7- 7.3 is noted as color. Start to change and 7.7 is that the color is not further pinker. ) KHG is 6.3.

With reference to the very consistent measurement of KHG, I decide to adj. the measurement by adding 1dKH.

I really don't think there is anything wrong with this tactic. I chose not to make an adjustment, because all of the information that my corals and tank were giving me was that i was actually running 1 dKH low. Since having raised it up there has been rapid and dramatic changes, so I think my experience in reading my tank was correct. (Always trust your gut instinct).

Have you calibrated the probe with 7.0 &4.01 test liquid?

Im getting password error for some reason when trying to submit a ticket. And resetting doesn't seem to work also. Can I send you an email?

btw I ran the test 5x and still only got 5.5DKH. I checked the reaction chamber and the small white agitator is there. Hope I haven't got a faulty unit.

Frankly, I subjectively trust KHG more than other kits. My sps always easily *burn* (stn) from the bottom (one sign of low KH) even the KH is kept at 7.x. Thus, I need to keep the KH at 8.x to avoid the problems.

Why I take adjustment? I just want to compare the measurement easily. I plan to raise my KH to 8.x -9.0 in long run.

I really don't think there is anything wrong with this tactic. I chose not to make an adjustment, because all of the information that my corals and tank were giving me was that i was actually running 1 dKH low.

I have asked the inventor about this question. This is 50cc water used (including cleaning, )

It seems to use quite a bit of tank water filling/purging/ cleansing the chamber. Is there a concern about salinity being thrown off?

Sorry if this was asked already and I missed it.

This seems that a connecting device to connect other general controller within months.

That is exactly the use I would give to it with the calcium reactor... more like a monitor...

Read the trend on the monitor and adjust the effluent doser... manually

Exactly the same that you are doing but you adjust your 2 part dosers.

So the real value of the product, as it is right now, is not the dosing... that part is just one tiny detail on the product that some will use but most will ignore....

If you, as manufacturer, could take advantage of the controller in the KHG, the testing capabilities and add to it the ability to control more than one doser and make the software more flexible and smart on controlling those dosers then you will have a GREAT KH controller

No, this is not 1500ml but. 1500g.

The inventor has said this is very critical to mix. the testing liquid with. 1500g (+-1g) ro/di water.

Frankly, I suggest the dealer may provide the service to sell well mixed solution for us.
Scale was used to measure out the 1500 ml. Same scale that was used to measure the 500ml for both of the dKh standard solutions

Thanks everyone. I thought about buying it but not anymore. I feel if they want 1k for a product it should work flawlessly, plug and play type.

So I got my replacement magnet/agitator (small white pebble).It which didn't come with and I did it test and got a TL_ERROR. Doesn't say anywhere in the manual what it means.

I was missing the small white magnet in the chamber. Coralvue sent me one but Im getting a TL_ERROR now.
Hanna and Salifert says dkH 9.6

TL_ERR = Too Long ? :rolleyes: (just my guess .......)
I have encountered such a situation, so I guess maybe your KRS tube filled with intermittent air.

May you can Re-execute the DE-GAS procedure, until you can see a drop for every 3 seconds and stable for more than 20 drops then press RESET to stop it.

Doesn't say anything about this error in the manual. You may be right. Any response from CoralVue on the error message?

The error isn't showing on the display record so maybe its only superficial.

I found if you use standard airline to extend the hoses they fit loosely on the check valve barb and can introduce air.

Look here !
So I guess the TL or L% = Too Long and TS or S% = Too Short to record the state of the drug dripping.

But now I have not met TS_ERR , hope that there will not be that day.:D

I wonder if anyone could take a picture of the back of the KHG unit , I need one for Geo's reef and will have to dismount my unit to get a picture and would rather avoid that if at all possible I am hoping that for some they can just turn the unit to get a pic?

Thanks everyone. I thought about buying it but not anymore. I feel if they want 1k for a product it should work flawlessly, plug and play type.

I think expecting a KH testing machine to be "plug and play" is probably a big stretch, especially since it is in it's infancy. You should definitely consider one in the future. Alot of what you see here is people struggling to learn something new. Everyone struggles learning something new. What you don't see here, is the fact that it's working! (It's working VERY well on my tank). I suspect that there are others that aren't having problems, or have resolved issues based on the experience of others here who it is working for too.

When I decided to take on this machine I fully understood that the major hurdle in this was going to be ME. After figuring it out, it is beautifully simple and elegant in design. Take it for what it's worth, but I could get up from my computer, and leave for a week, and my tank would be cool. That wasn't true before the KHG. ;) This is a revolutionary change in our "lifestyle" you don't see that in this thread (unfortunately). It's difficult to explain without experiencing it.

I fully understand not wanting to be an early adopter of a technology like this, there are inherinent risks. But don't count out KH machines yet, let them evolve a little before drawing a final conclusion. There will likely be changes to this machine in the future based on experiences of users like us in this thread. :)

Mine is in a bad place to take a pic (I tried) sorry man

I've noticed this too. The only runs I used standard airline tubing for were the SW out to my waste container and to extend the dosing line to where I wanted it in the sump. So fortunately the machine isn't affected by the bubbles. It probably would be wise to pick up some additional tubing like the original included with the machine, I'll have to source some.

I will get mine on Tuesday and can post a picture for you.
