SRC Member Mike Stone Posted September 20, 2016 SRC Member Share Posted September 20, 2016 I am using Hanna to measure Alkalinity KH which I think is important to be accurate and also it's easy to measure using Hanna.Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
SRC Member quarantasei Posted September 21, 2016 SRC Member Share Posted September 21, 2016 Any particular reasons?Sent from Singapore Reef Club mobile app The cost is lower for Salifert compare to Hanna.

SRC Member vincentwangz Posted September 21, 2016 SRC Member Share Posted September 21, 2016 I have two Hanna checkers. One for alkalinity and one for phosphates. Once the reagents run out, you basically have a white elephant until you restock them. And the ones given in the kit actually cannot last you for long. That's the drawback for using a Hanna checker. These days I use the Nyos phosphates test kit to measure, and then put the solution into the Hanna checker to counter check. Haha.

kilo Posted September 21, 2016 Author Share Posted September 21, 2016 Thanks all. I am happy with NYOS tester for Mg, Alk, Nitrate but have tough time with calcium. From the replies, i see Mixed feelings. Key note, Hanna is not cost efficient, got digital readout. Need to sleep over itSent from Singapore Reef Club mobile app Quote Link to comment Share on other sites More sharing options...

SRC Member vincentwangz Posted September 22, 2016 SRC Member Share Posted September 22, 2016 I agree for the calcium test kit it does not change the color very significantly. I too had to do the test twice to be sure. Sofishticated Friend Quote Link to comment Share on other sites More sharing options...
SRC Member dsam Posted September 22, 2016 SRC Member Share Posted September 22, 2016 NYOS calcium test kit you got to be really patience and drip and swirl until it really turns blue. Quote Link to comment Share on other sites More sharing options...
kilo Posted September 23, 2016 Author Share Posted September 23, 2016 The pink is very light and translucent and the blue the same. Can't even see properly whether its changed to blue. Sent from Singapore Reef Club mobile app Quote Link to comment Share on other sites More sharing options...
SRC Member Mike Stone Posted November 14, 2016 SRC Member Share Posted November 14, 2016 I can't get the solution to turn blue even after dosing 1ml of component 3. Tough to use for Nyos Calcium Test Kit.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Joboh Posted November 15, 2016 Share Posted November 15, 2016 Salfert test kit always shows undetectable phosphate since The 1st test. I really doubt the reading is correct. 1 Quote Link to comment Share on other sites More sharing options...
SRC Member Mike Stone Posted November 15, 2016 SRC Member Share Posted November 15, 2016 Joboh, I am referring to Calcium. Do you use Salifert and is able to detect Calcium easily?For phosphate, I am using FM Pro kit which is easy and reasonably accurate.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
SRC Member Mike Stone Posted November 15, 2016 SRC Member Share Posted November 15, 2016 Did some searching on Internet and realised that Nyos Calcium Test Kit tends to give high reading, which what I am facing too.Looks like I need to switch to another type of Test Kit.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Joboh Posted November 15, 2016 Share Posted November 15, 2016 No problem for calcium reading. Think I have to switch to FM pro kit for phosphate testing to have a piece of mind. Quote Link to comment Share on other sites More sharing options...
SRC Supporter Harlequinmania Posted November 16, 2016 SRC Supporter Share Posted November 16, 2016 For a more accurate reading, I usually test twice when in doubt and take the average of two reading (if is different reading) to determine the result Sent from Singapore Reef Club mobile app Quote 1000 Gallon Tank in the Hole http://www.sgreefclub.com/forum/topic/120957-1000-gallon-3d-hole-in-the-wall/ Link to comment Share on other sites More sharing options...
