I apologize if this has already been asked. Is anyone dumping the discharge back into their tank after a test or is everyone running it to a waste container? I got in on the early bird special for the discount but have yet to set up my tank as it will not be ready until mid April. Thanks for the answer.

I dumped into the skimmer but it overflowed twice cause it's a decent amount of water. Moved to a separate container outside of my stand
Didn't see any affect on tank when it overflowed but makes me nervous

I'm not sure. I would be inclined to think that it will still be reasonably accurate.
I don't think returning it to the tank will be a problem, that being said I save mine in a container and dump it down the drain. I replace what it takes out with fresh saltwater.
The other day I remember there being a post to a facebook group I follow regarding an update for the missing digits you guys are experiencing. Has any of you contacted coralvue for the update? I didn't even bother because I have yet to setup my KHG.

I noticed that post in the group too! I will be sending them an email very soon! 
I'm excited!

The %1 and %2 is a measure of when the unit pulls reagent for a certain length of time but a drop doesn't form.

I am testing a new version of the PCB board and I think it will satisfy those people looking for increased accuracy. The new PCB board has a few changes including:
- Static IP address
- Compatible with the upcoming "Advanced Interface Module" that will allow you to connect the unit to a 3rd party controller
- Does not round off results to 1 decimal point therefore increasing it's testing accuracy

Here is a picture of my Data Log with the new PCB board. You judge for yourself!

Awesome Carlos! When will these become available for us?

Probably in the next couple of weeks. We need to test them to make sure they are ok so we want to let them run for a little bit to gather enough information!
Check this out as well....

That's really exciting! Oh man, that's totally made my day, the KHG just got even better.

No, the unit uses a dosing pump to drain the testing container. It is not gravity drained.

It all depends on the size of your tank, how many times a day you test. Too many variables for it to be a viable universal statement.

One liter in a 600L system over several days doesn't account for much of a change in salinity. If I never replace it eventually my salinity would drop because the ATO would automatically replace it. But the frequency that I do it doesn't amount to any noticeable change.
