I would suggest reading this article by Randy:

http://www.reefkeeping.com/issues/2004-06/rhf/index.php

Here is the excerpt in which he refers to what I was talking about:

It is widely believed that only pure water is required to calibrate refractometers. That fact is true of many refractometers, and is certainly appropriate for routine calibration, but it assumes that they were manufactured correctly and have not been damaged since manufacturing. As refractometers used by aquarists become less and less expensive (with some now selling for less than $30), there is every reason to believe that at some point they will no longer be accurate enough.

The only way to be sure that a given refractometer gives useful information is to check its accuracy in a solution similar to aquarium water. I believe that all refractometers should be checked in this fashion when first purchased, and again any time there is a reason to be concerned. For example, an aquarist might be concerned if an aquarium that had been running for years at a salinity of 35 ppt suddenly reads 39 ppt.


So what I really should have said is you shouldn't use RO or distilled water if you want truely accurate readings.

you can calibrate using RO water.. i have read about it every where.. dont just do what randy says Psyire...
 
Yeah, my Sybon refractometer came with a little bottle of "ultra pure water" to calibrate with. I do not know how "pure" it actually is but that is how I will calibrate mine as soon as I need to.
 
Topoff Programming

Topoff Programming

Alright...Hate to get this thread back on topic guys... :lol: ...but I have an auto topoff programming question. I will be connecting a pump to my Aquatronica power bar so I can control topping off water in my sump. The pump will be in the container of some sort (5g bucket maybe) and will have a water level sensor on it to keep it from running dry and burning out the pump. There is also a level sensor in the sump. I want to be able to program it so when the sump sensor is activated (low water level) then the pump will activate until the level sensor is deactivated (water level is restored) OR X number of minutes (I will figure this out later). The second part is just to catch a stuck level sensor or something. Can I do this?
 
Re: Topoff Programming

Re: Topoff Programming

Yes you can do that, just program the level sensor in the bucket to switch OFF the pump when the level in the Bucket gets low, but do NOT program anything on that sensor to turn ON the Pump.

Next program the Level sensor in the Sump to turn ON the pump when the level in Sump gets low and to Turn OFF the pump when the Sump level is Normal.

To catch a stuck sensor put a timeout on the Sump Level sensor for 25% more time than the Maximum time you figure the pump will run normally. On mine I have it set to 180 Seconds and if the RO is still running then it gets shutoff and locked out.

Have fun, now can we go back off topic? :D Just kidding :)

Actually Psire I am a bit confused by what Randy is saying but I guess the real test is for you to calibrate yours with RO then take a reading of your Calibration fluid and see if it's correct.

Just because you can, dosen't mean you should. What Randy is saying makes perfect sense.
 
Pysire did you try an RO calibration then see how close it is with the Calibration Fluid?

Personaly if I have to use Calibration fluid on a Refractometer it looses half of it's value to me! I have found that all these fluids tend to go off within months of being opened and used, with the salinity fluid if the bottle top gets left off to long or your probe has a little excess FW on it when dipped, the liquid gets contaminated and starts changing value. I like the idea of RO water being the only thing needed, I hope that Randy is wrong.
 
Well... some results are in but the jury is still out.

I'll post my complete findings later tonight but I'll tell ya right now that if I believe both bottles of Aquatronica Calibration solution then my Refractometer was reading .003 off. (Both bottles read the same @ 1.022 when they should be 1.025) The only calibration method I have used on my refractometer since I got it was the RO method, until now.
 
unrecogonizable device

unrecogonizable device

I posted this in the aquarium obsessed forum but thought I would ask you guys. A few days ago my controller stated that my redox was disconnected. I hit enter and proceeded to unplug it and plug it back in. After I plugged it back in I got this message that a "unrecognizable device was detected, please unplug and then hit enter" or something like that. I made no changes and it was working great up until a few days ago. I tried unplugging other items and swapping out the USB cords but I still got the same message. Everything else works great. It is currently unplugged. Anyone else encounter this?

Thanks in advance,

Clint :cool:
 
Backup your config and reset it and then uplad the config again. also you may want to try first going through manully on the controller to the program for the redox prob and select disconect and plug it back in.
 
it makes sense to me to use ro water. if that is what the manufacturer says to do. if some ro water evaporates you still have ro water. If calibration fluid evaperates old etc etc it can be off. I wonder which is best?
 
I haven't posted my complete findings yet because I've had to do some more research. I've borrowed another Refractometer from a friend so I should be able to verify my results between the two Refractometers and the Salinity Probe.
 
I just want to butt in here for a sec and give a BIG Thank You to Will @ Aquarium Obsessed. I got myself in trouble last week with my Aquatronica and Will really took care of me. Both Will and Ron have been nothing but fantastic with me and I cant thank them enough for it.

I am really happy with my Aquatronica purchase and the effort put forth by the entire AO Gang. These guys have gone above and beyond normal customer service.

Thanks Guys for putting up with me.

Ummmm....

Long story short, Aquatronica controller, pH interface and Powerbar under 4" of salt water.

Along with some other stuff... :(


It was a bad bad day.
 
Wow what a tragedy! This begs the Question, Whats the Long story?

I had some trouble while down loading the last update. The internet update was successful to the hard drive, but during the down load to the controller, the down load was interupted. The controller wont power up at all now. Any one have any suggestions?
Thanks in advance,

Todd
 
REEFGREENER,
I believe there is a way, I think I read how it can be done earlier in the thread. Your firewall may have been the problem. RobbyG might be able to answer or maybe Ron.
Other then this problem what do you think of the controller?
 
Reefgreener I think you have to send the unit to AO for repair/replacement. When a Firmware update is interrupted it leaves the unit essentialy Brain dead so in most cases it no longer knows how to accept any updates or even how to switch on. Some Hardware is made with a small backup programme that can be activated in such cases but I doubt that the Aquatronica has this feature since its very rare.
