Coral closes up after water change.

ADAMMP · 12/03/2016, 05:38 PM

Hey everyone
I was wondering I have one Coral that kind of retracts after I do a water change. Does anyone else experienced this? The only thing that really changes is my nitrates go down and my alkalinity goes up. Alkalinity is usually 8 to 9 after a water change its usually around 11. This is a picture of the coral that does it. None of my other corals react.

Its fairly normal for corals to close up during a water change/when disturbed..
Sounds like you might want to look into dosing to maintain stable parameters between water changes.. A swing in alk can cause issues..

Isn't 11 a little high for alkalinty.

Flower pots are very sensitive. 11 does seem high for a salt mix. What brand of salt? Are you adding a buffer to your mix?

Instant oceans reef crystals. What buffer is best to use? Thanks for any info.

You could also consider smaller more frequent water changes to prevent the big alk swing.
