Hannah testers opinions

Recommended Posts

I'm considering picking up the relevant digital testers from Hannah for reef tanks. Red Sea and API have taught me I have a hard time telling colors and that apparently all my bulbs are different color spectrums...

 

Are the Hannah testers worth the investment?

Alk and low range phosphate.

 

Stay away from calcium.

I love the phos ULR and alk. They make it so much easier for testing.

 

I use other kits for everything else.

Anybody using the ultra low range phosphate yet?  I know it’s pretty new.  I wonder how it compares to the ultra low range phosphorus?

What other kits are recommended? What about the salinity tester from Hanna?

They are slow to use compared to common drip tests and the labware makes them more fussy to get good results with, but they are accurate and eliminate the need for color judgement.  I think for the price they are a bargain.  That said, I still use my drip tests 98% of the time....faster and a little cheaper per test.

 

@Thrassian Atollthe ULR phosphate just reads in different units than the phosphorous tester (ppm of PO4 vs ppb of P)....same otherwise.  Older unit comes with a conversion chart. 

 

I own and recommend the plain mid-range phosphate unit anyway....covers a wider range of readings up to 2.50 ppm and the accuracy is fine for avoiding zero.

I believe they are identical...just the new one does the math for you to turn phosphorus to phosphate reading and has a longer shut off time.

I use the salinity and temp tester. Love it. Just have to keep it calibrated like any other instrument.

Alk and salinity both amazing and highly recommended

Be careful with the EC salinity tester. You apparently can't test tank water as the solids in the water interfere with the conductivity and can give false readings. It is good for mixing fresh saltwater with 0 TDS RO/DI water, but as I needed to use a refractometer anyways to test the tank, it wasn't worth the extra effort and cost so I sold mine.

Really? I hadnt read about this before. 
 

I'll have to do some more research. Thanks for the heads up.
