elos or salifert

[JOEL]

I just tested my water with these test kits. They are not out of date.
Here are my results.

Alkalinity

elos 10
sallifert 11.05

Calcium

elos 550
salifert 425

Magnesium

elos 1550
salifert 1230

This is using my new makeup water io reef crystals with a specific gravity of 1.025.
Which test kit is right?

clean everything with really hot RO water and redo the tests. re-read the instructions to make sure you doing everything to the "T". Hold everything perfectly vertical when adding drops of reagents. Holding the bottle at an angle changes the amount of reagent that gets dropped.

The elos is suppose to match the hanna for kh, sailfer usually testing 1dkh higher.

Just finished testing mine. Elos measures alk. @ 9dkh

New Salifert @ 12dkh.

Just wonderful. Plus the alk. testing sample in the kit is dry/empty.

Give me back my old FasTest alk kits.
