Alkalinity Measurement

[kadamik]

I have a saltwater fish only aquarium and i just got some testing numbers back from a SpinTouchFF

My question is around the ALK it seems high, if so how should I lower it?

75 Gallon Aquarium
1 saddle puffer
1 snowflake eel
1 long tentacle anemone (Pink with white tips)
1 BTA
1 very small Rose BTA

ALK 276 PPM 15.43 dKH
pH 7.9
PHOS .5
Ca 313
Mg 1016
Ammo 0
Nitrite .1
Nitrate 10

Unless you're dosing alkalinity, I'd re-test it with a Salifert (etc.) kit. That reading seems abnormally high.

Do a water change with a less alkalinity salt. It’s weird that nitrifying bacteria is not eating up your alkalinity. I’m unaware of other ways to lower alkalinity.
