PH testing, and Alkalinity Questions
 

Hey guys. I need some Ph and Alkalinity testing kits. What is recommended? Has anyone found some to be more reliable/unreliable than others?? Where can I get digital ones?

And oh yeah, where's the best place to buy test kits????

I just bought some Seachem, I hate them, too much work... I have just ordered and going back to ELOS, very accurate and simple to use.

Thanks. What's ELOS, and where can I get it??

The API test kits are also decent and easy to use for KH.

Most LFS have ELOS, but I get mine from jlaquatics.com, they are cheaper on there. Very accurate test kits.

I have never used API, but here they are decent also.

API for KH, it is cheap and accurate and always consistent. Matches my more expensive Lamotte. Elos is good too. Salifert had a bad batch of KH test kits years ago and I would never trust them again, more so out of principle for denying it. For Ph gets yourself a monitor

OK, so where can I get a ph monitor?? :question:

got mine here off Canreef but JL Aquatics carries different ones.

I'm using Salifert for Alk, no problems and last couple I got had a calibration solution to check against.

For alkalinity I would say Elos is a good kit (or Hanna or LaMotte if you're into spending that kind of money).

For pH I wouldn't bother buying a kit as they are quite inaccurate. A handheld digital pH meter (buy calibration solution too for pH 7 and pH 10) is much more accurate.

I have a Salifert kit for alkalinity and even though it matches the calibration solution they send with the kit the kit reads 2 dKH higher than accurate, my last one was 3 dKH higher than accurate. I won't buy another Salifert kit for alkalinity.

THanks, very helpful. where is a good place to buy the handheld Ph testors??
