are hanna checkers worth it

[William Chiavetta]

I was thinking about getting hanna checkers but I'd need 7 different ones and I dont really have $500 I guess I could buy them used but it would still be expensive and I'm not sure it would be 100% working.

Get new ones. Alkalinity is the most important. Then maybe save up to get phosphate and calcium.

For me i prefer hanna for phosphate and nitrate since the general kits vary in range and hanna is more. Accurate for those. Cal, mag and alk i use salifert qs my backup test kits and i get 100 uses compared to 25 per reagant for hanna.

I would not think you need 8 of them.

I like the ones I have except Magnesium

Alk, High Range Nitrate, ULR Phosphate, Phosphorous .

Hanna's calcium tester is a little sketchy but you dont really need to worry about calcium and alk if you dont have coral.

what about ones to measure the nitrogen cycle, calcium, and ph

I am planning to get coral

why get new ones?

Aside -- Hanna makes the Marine Master checker that does a bunch of parameters in one unit for <$500 so you could check that out.

I like the Hanna checkers that I own but I only have 3,,, and I'm color blind,,, so there's that.

If you ask me it is worth picking and choosing. My favorites are the Alk, Ultralow Range Phosphate, and High Range Nitrate. These all use 1 reagent and are some of the most accurate and easy to use.

Some of the other checkers use 2 or even 3 reagents and are not the most accurate. The checkers are not the best for measuring everything.

Horrible reviews on the calcium one I use a Red Sea test kit for that.

No reason to test nitrite.

I would just get a test kit for ammonia

I have the Hanna alk, phosphate and high range nitrate. I use a Red Sea pro kit for calcium. I haven’t seen a need for anything else. Magnesium is rarely checked.

 

[tzabor10]

why get new ones?

Because I jacked up one of mine while testing one night. Put reagent directly into the checker with no cuvette. You could also be getting scratched glass. Glass could also be stained. If parameters are your goal, don’t you want to have trust in the process ?

This right here

Which 7 parameters do you want to test?

I was thinking ph, Kh, Nh4, No2, No3, Po4, and ca

Are they worth it?

For phosphate: yes.
For the rest of the parameters? NOOOOOOO.

Salifert is more accurate when it comes to alkalinity, calcium and magnesium than Hanna will ever be. Titration is simply more accurate than extinction photometry. That's a physical limitation.
And when it comes to nitrate a result like: between 20mg/l and 10mg/l is usually close enough.
