Hanna Phosphate Checker

[drm180]

Has anyone ever used one of these? Hanna Instruments Checker Colorimeter Accessories
I am having algae problems even though my API test measures zero phosphates. This seems to be more acurate so I think I should invest in one. I'd just like to get some reviews before I spend the $85 on the checker and the reagents.

No, but I have this one and I love it.

I haven't used that specific model, but I know that Hannah instruments are generally quite reliable... used them at work all the time.

The one I have is extremely easy to us too. I wish all testing was that easy. Maybe I'd do it more. I hate counting drops and guessing colors.

 

[drm180]

Yeah. The color differentiation is really hard for me with other test kits so I thought this might be better.

 

[tankedchemist]

you could go one better and get a UV-VIS instrument. They're several hundred thousand, but you wouldn't have to guess the colors of anything anymore-- it would give you the precise wavelength. :D

No, I haven't actually done this with my hobby test kits. Really. Stop looking at me like that...

She's a nut. :mrgreen:

 

[drm180]

That's perfect! I'll get one right away!

I have one of those and love it. The color guessing was honestly a waste of time. My tank has a PO4 of 0.03 when I got it and I now have it at a steady 0.01 and the bit of algae growth I did have is totally stopped. I have all of their new meters except Iodine and love them all.

They are a bit pricy, but if you're in the hobby long enough then they will save you money and a lot of time.

Dcan you couldnt find more things to buy in order to save you money! :)

 

[dcantucson]

Yeah.... it's kinda, ironic don't you think?
