Hanna meters

I need to get new test kits and was looking at the Hanna meters. Does anybody have any experience with these? Good or bad?

Thanks,
Andrew
 
PO4 is good, Alk is good. I'd stay away from the Ca meter, there's been a lot of complaints and I'm not sure they've solved the problem(s).
 
Little trick with the phosphate reagent that I saw somewhere. Rather than cutting one side of the foil package, cut two adjacent sides so that you can pinch it together and make a little funnel. Makes it much easier to poor the reagent into the vial.

I use all three. When using the ca make sure you rinse vial several times with fresh RO before and after use for a more precise reading.
 
thanks everyone. it sounds like PO4 and alk are the way to go.

Also I dont know much about the different controllers. Is there such thing as a contoller for my tank that will have a probe in the water to tell me what the alk, cal, mag, and PO4 is constantly? I know that there are contollers for temp, ph, and other things but not sure about others. Any info would be helpful.

thanks again,
Andrew

There was a report on reef builders towards the end of last year for such a device. It would be seneye like, but would constantly test for alk, nitrate, calc, etc etc etc. However, I have seen nothing on it since it was mentioned there and the price was going to be pretty high (IIRC like 600$ range).

I agree on the Alk and Phos meters for Hannah. Have never tried the Ca, but heard too many horror stories to bother trying it myself.

Having a probe/controller to test for all this stuff would indeed be the holy grail, and I'd consider paying $600 if it was available. The problem with testing most of these parameters is that they require reagants to determine the reading. That's something that reacts to specific chemicals to reveal the reading (changes colors in different ranges).

A probe that could just "sense" a particular chemical would give you constant and (when calibrated) more accurate readings without having to keep buying reagants that get used up with each test.... so yea, that would be awesome!

When it comes out I think it would be worth it as well. I will see if I can dig up more info on it tonight as reef builders is blocked here.

An X-Ray Flourescence Spectrometer will determine elemental analysis without the use of any reagents. I am not aware of an "automated" machine, so you'd have to figure that out. Out of curiosity I checked ebay.....found two used machines....one for 16,000 and the other for 99,000. Maybe we can do a group buy and move it from house to house.....although it is rather large.....throw in a fork truck. :p
