Are you sick of guessing ? having issues you just cant get sorted ? maybe its time to use a Triton Test kit ?
you guy the testing satchel , inside there are 2 vials , you fill these to the top with your tank water , both the same tank please . then regester on their web site using the info provided on the package .
Then you ship it to cairns marine in cairns , and wait , once trition get it they test your water using the most sophyticated methods and give you a detailed result which you get on their web site , its simple and easy , doing this sort of thing every 3 to 6 months can really keep a check on your levels and stuff you simply cannot get tested ,
Well worth it for peace of mind .
