API test kit...

[oldhead]

Is there any reason why an API freshwater test kit would not work on a saltwater set up? They both test for the same things and the freshwater has a high range ph test with it? Just not sure if I should go spend more money on another test kit if it's not worth it.

Usually the API test kits work on both sides. They will have a card for FW and a card for SW.

agreed 2 cards 1 for FW and the other for SW

I have the master test kit for freshwater and it only has 1 set of cards. Perhaps it's for both and I just never noticed? I just can't seem to find a difference in any of the tests.

Thanks. I already plan to purchase the reef kit today. But when viewing the fresh and salt master kits they both contain the same tests. This is where I'm confused. I can't see why I wouldn't be able to use my fw kit on a sw tank. I tried to call them but got no answer. I don't wanna spend the $$$ on a sw kit if I don't have to as I already have the fw.

So there might be a difference in the make up of the solution or the chemical reaction obtained? Bah, maybe I'll just break down and buy the sw kit. I just hope I'm not wasting money.

I see no difference to them, either, and don't know why the freshwater wouldn't work.

Either way, I don't think your wasting money on buying the master reef test kit.

There are tons of other things to test in reefs that you would never even condsider in FW, and it is good to know what your levels are.
