grassi Posted October 14, 2010 Share Posted October 14, 2010 I've found this interesting test conduced by an italian online reef community. http://www.acquaportal.it/_archivio/articoli-3/test_sali3.asp Even if the text it is in italian, it is ready to understand, I mean the tables with numbers lol Check out the tables for ph, alk, amm, phosphates and so on. I like that they used 2 test kits (salifert and elos). Interesting also the difference obtained with the test kits (check out for instance the 2 readings of Calcium for Kent). There are some salt mixes that we don't have here, but most of them are available here too. Quote Link to comment Share on other sites More sharing options...
NoobtoSalt Posted October 14, 2010 Share Posted October 14, 2010 Calcium and Alk were both quite a bit off on the Kent. I was having issues with their salt recently and it has been dropping but I wonder if my kit is off as well? I've been using the ELOS but it appears in this test that they run a little higher on the Calcium test as well. Mabye I should get a salifert and try it out against the ELOS kits.

ReeFit Posted October 14, 2010 Share Posted October 14, 2010 as long as your #'s are consistent, switching test kits isn't really going to prove anything. the only way to truely figure it out is to have a lab test for it. all that switching test kits will do is show the differences in the manufacturers methods for testing. if you suspect a bad test kit then testing should be compared to the same brand and type of test kit.

tanktop74 Posted October 14, 2010 Share Posted October 14, 2010 I use Kent salt and Elos test kits and my numbers are similiar. Ph always about 7.8, kh 8.5-9, cal 500, mag 1200.

grassi Posted October 14, 2010 Author Share Posted October 14, 2010 Ryan is right ) Forgot to mention that the salt mix they tested were obtained directly from producers/distributors, so probably at the best condition as for humidity and storage Quote Link to comment Share on other sites More sharing options...
Electrokate Posted October 17, 2010 Share Posted October 17, 2010 Pretty big discrepency between the Elos and Salifert alkalinity kits, would like to know which is accurate Quote Link to comment Share on other sites More sharing options...
CCR Posted October 17, 2010 Share Posted October 17, 2010 Pretty big discrepency between the Elos and Salifert alkalinity kits' date=' would like to know which is accurate[/quote'] That IS the question of the day Quote Link to comment Share on other sites More sharing options...
Electrokate Posted October 18, 2010 Share Posted October 18, 2010 Salifert alk test matches API, have tested several salifert batches vs several API batches. The Salifert kit also comes with a calibration solution... Guess I will stick with those 2. Quote Link to comment Share on other sites More sharing options...
grassi Posted October 18, 2010 Author Share Posted October 18, 2010 Also the API comes with the calibration. I'm gonna buy an Hanna photometer and I will check API against that soon Quote Link to comment Share on other sites More sharing options...
