Too close too vortech?

[Mick51]

I got this milli about 3 weeks ago and it’s been perfect until this Morning there are a couple of tips going brownish it’s not chemistry only this coral and just these couple of tips, could being too close to the vortech stream cause this ? Thanks

In my experience Milli's like a ton of flow, but that looks very close to the vortech. Maybe try moving the vortech a few inches and see if it helps?

In my experience when your sps tips brown out it’s water chemistry
Something is off or unstable
Test your water ever day and track to see what your range is
Test your
alk
Nitrates
Phosphate
Calcium

test the first 3 everyday and see if the range is the same
