Enthrol Posted February 15, 2020 Share Posted February 15, 2020 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? Quote Link to comment

Alk and low range phosphate. Stay away from calcium. Quote Link to comment
Clown79 Posted February 15, 2020 Share Posted February 15, 2020 I love the phos ULR and alk. They make it so much easier for testing. I use other kits for everything else. Quote Link to comment
Thrassian Atoll Posted February 15, 2020 Share Posted February 15, 2020 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? Quote Link to comment
Enthrol Posted February 16, 2020 Author Share Posted February 16, 2020 What other kits are recommended? What about the salinity tester from Hanna? Quote Link to comment
mcarroll Posted February 16, 2020 Share Posted February 16, 2020 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. 1 Quote Link to comment

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. 2 Quote Link to comment

burtbollinger Posted February 17, 2020 Share Posted February 17, 2020 Alk and salinity both amazing and highly recommended Quote Link to comment
Garf Posted February 17, 2020 Share Posted February 17, 2020 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.

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