SeaChem Reef Salt - alk testing

[MadDogNoz]

Hello and thank you for the wonderful support system.

I have been using SeaChem Reef Salt since starting my new system 55G cube about 6 months ago.

I am a little perplexed at my KH results. I use an API test kit. I seem to be continuously getting 6 - 7 dKH levels.

Someone mentioned to me the borate in the SC Reefsalt and suggested to either change salt brand or test kit.

SeaChem test kits are not always readily available in Australia and if found, they are priced very high (even on comparison of the US sites where I find the costing is far more comparible to other quality grands). The API kit is new ... while not overly pricey I hate throwing money away (I have done enough of this in this hobby).

Are you able to give some guidance as to the comparison of what the API kit is measuring to how the borate in the salt may be interfering with the result?

I'd love to see a better range of your test kits readily available here but until then, this is what I have to work with. I need to know whether I need to raise my KH or not ... and if so, how much.
