no alk consumption…

[cmmatxh]

is it normal for my tank to not consume alk?
i haven’t done a water change in two weeks and it’s still the same. i am testing with hanna checker
tank age : 6 months

Are your other parameters stable?

Questions:

Do you use a dosing pump? Have you checked the Hanna against another ALK test? Whats your calcium? Coral can't use calcium without ALK....

What's your other levels like?

i am not dosing anything besides 4ml daily of redsea ab+. here are my calcium and phosphate results as well

Nitrate rising can also introduce alkalinity I think I've seen @Randy Holmes-Farley say.

Red sea ABC+ contains Alk. Stop dosing and see if your levels drop.

If you don't have a bunch of sps and coraline it can happen. You substrate can also buffer the tank. I wouldn't worry about it too much.

It's the opposite. With rising nitrate, alkalinity is bound up. Once the nitrate is remove via denitrification/organism uptake, the alkalinity will be released. This might not be the technical explanation, but it's along these lines.

makes sense because my nitrate is pretty high rn due to no water change (22.3 ppm)

From looking at the tank, it appears to be new and also LPS dominant. LPS use far less calcium/alkalinity as they are very slow growers. Many LPS tanks are fine with just water changes.

yes mainly torches i tried to keep “easy sps” but they don’t make it past 2 weeks
