Damn, I was really hoping those would have become a bigger thing...more affordable. Okay thanks a bunch, I'll look into those brands, they last a long time?

I'm the exact same, where did you get your elos kits from?

Are you refering to the Hanna Checkers? The alk and po4 checkers are great. The Ca one imo is poorly designed.

I think its iDip

Maybe. I assumed she meant a longer time period ago.

Hey buddy these I've had for a few years some have expired but I just use the Elos up since I already have it. I obviously check after with a new box of salifert... certain test kits are ok to use if they haven't been expired too long for instance when I check my Hanna alk which is expired against the salifert they are only off by .03/4. But for Hanna I would advice if you have expired or close to expired po4 tests to not use because they're off by quite abit.

Your original question about salt I like aquaforest reef salt

Neither.

The most important thing is stability, within the broad parameters that the living things you want to keep in your tank need. In over 30 years of fishkeeping, including 15 years of saltwater, this is what I have found gives the most successful tanks. Whether you manually add and test, dose and test, or use reactors and test, the most important thing is to keep stable parameters and test. This will give you a successful tank.

Alright so I see some common salt favourites, good to know. I'm not actually new to saltwater reef keeping, its just been 5 years since I had a tank and wanted to see if any new technology was out since the hobby is constantly advancing
