High Alk Problem

[orangetang]

Bumping an old thread here, but it seems to be the place to discuss...

My alkalinity measures 22 dKH, confirmed on two different branded tests, on a freshly mixed pail of Instant Ocean from RO water at 24 C.

I bought some snails from a marine pet store and but their water to the same tests, which came out to 28 dKH.

Both of my aquariums seem to run at ~20-22 by these tests and all inhabitants seem to be happy.


What is going on here? Is it as simple as dividing by 2 ?

What brand of test kits are you using and how old are they? Sounds like they belong in the garbage

An API and a Hagen. Both are new.


The API test strip shows ~180 ppm "ISH". So ~10 dKH.

If they're new and you have a receipt then maybe you could take them back for a refund? I'd suggest Salifert if you can find one locally?
Both of those brands are notoriously unreliable
