One thing hobbyists tend to go back and forth on are test kits and that's due to various reasons. I would like to hear what everyone is using for the big three (alk, cal, mag) in 2021! Which do you trust the most and why? Let's talk about it!

1. What brand test kits are you using for Alkalinity, Calcium and Magnesium in 2021?

2. Why are you using the test kits that you are using?

Currently using the Trident. I would be happy to switch to something better. I often find myself checking the accuracy with my Hanna checkers. Maybe Alkatronic and Mastertronic next.

I use Hanna for Alk & Cal & Red Sea for Mag. Have used them for years and like the consistency.

I test Alk weekly, Cal every 2 weeks & Mag monthly. My 2 tanks are literally on cruise control & this keeps them in check.

I use

Calcium - NYOS
Magnesium - NYOS
Alkalinity - Hanna

The NYOS are very simple to use and fairly accurate against Triton tests and the Hanna’s also very simple and easy

Red Sea test kits Alk, Mag, Ca N03 and P04. I use the Red Sea "My Recipe Wizard". Dose Red Sea A B C and trace elements daily as prescribed.

I probably don't test enough but it never seems to change and is very stable.

Hanna ALK, fast and way way accurate. Can be done in less than a minute.
Salifert for CA MG, fast, easy, uncomplicated and accurate.
Can be done in less than 2 minutes.

The Hanna CA checker was too unreliable for me, the output varied way to much and it required quite a few steps.

The Red Sea MG was accurate but to time consuming have to shake for 15 seconds on every drop.

Alk - Hanna
Cal - Salifert
Mag - Salifert

Using these because an older (read wiser) reefer suggested them to me. Also they are cheap for the amount I test.
Another vote for this trio of test.

I use Red Sea for the top 3. Switched from Salifert a couple of years ago. I just seems easier to use and easier to read. The consistency also seems good. When I purchase a new kit, I always test the new against the old, and they seem to be pretty much spot on.

ITS Exact iDip - for everything plus...
Hanna for copper because I already had it,
Amazon pH meter for quick checks between real testing,
Hydros pH probe in the big DT,
Amazon TDS meter for quick checks to verify my IceCap RO/DI system.

I think that's all of them! I never trust any single source of testing, never!

I'm partially colorblind and even with color-sighted family living with me right now (thank you Covid), there's rarely a concensus on color chart tests. I vowed to go "digital" and never look back. So far, so good.

And an.........

Instant Ocean hydrometer.
I too use the Instant Ocean hydrometer. It's cheap, easy to use, and seems pretty accurate. Only complaint is the needle sometimes getting stuck with salt.
