Curious to hear thoughts about the applicability of this device in our hobby. Is anyone using it or have experience with it? Yes, I know the cost is high but I would like to leave that factor out and try to focus the discussion on the technical and practical uses of this.

I tried to do a search on this but didn't find anything, so if this has already been discussed would appreciate it if someone could direct me to it.

How much exactly?

It sells for $400

The phosphate and nitrate tests are the more useful parameters it can measure. The pH should be okay, too. I don't think it's worth the cost. Many of the tests won't work with seawater.

Interesting, I while back on reefbuilder there was a link to reef marketed photometer that sold for what I think was $800 (sorry cant find on site).

no3 and po4 would have the most benefit, likely do to accuracy vs effort.

The manual is probably I good starting point for test method, reagents as well. ebay shop for a photometer. If your anything like me, you find it pretty cool to own lab equipment. My man cave is actually referred to as the lab.

i dont think its worth the cost for really not all that important test in an established tank except for phos and nitrates.
API $6-10 kits will get you by for the rest of all the parameters indicated.

Well confirmed with Hanna that the majority of the tests will not work for saltwater application. So useless at this point.

You would be better off with something like this: http://www.hach.com/dr-800-multi-parameter-colorimeter-configurator/product-configurator?id=11171572400&callback=bc
These things work great, and are pretty simple to operate.

Thanks acroman. I'll take a look at it.

I also came across the LaMotte Smart3. Contacted LaMotte and spoke with one of their techs. This unit is supposed to work with saltwater (referred to as saline water in the manual) for the following parameters: pH, ammonia, iodine, nitrites, nitrates, copper, phosphates, phosphorus, and silica. Obviously saline water and ocean saltwater are not exactly the same, so curious to know how much this matters.

But not asking for a cost benefit analyisis - more interested in the discussion of the technical aspects of it.

Beware that saline water, salt water, and seawater may have different connotations. When you ask, don't ask about saltwater, ask about seawater.

When they say saline they are most likely only talking about just NaCl. Useful for some, think medical, but not us.

The Smart3 won't work with seawater for most parameters unless it's been changed drastically lately. The same was true for the Hach product line as well.

Okay good to know. Thanks for the input everyone.

I have been using the HI 82203 since over a year now. It gives very reliable readings. It is the one that is advised by HI to be used on salt water (reef) aquariums. Most of the other test that the other 832XX series will not work on salt water.
