Kh too high, way too high.

[Just a Wrasse.]

I set up another nano tank recently and I had to use tap water which has really high Kh. My Kh is now at 17dkh(tested twice) Shiuld I be worried the high levels should hurt the fish? I’ll do an RODI water change later.

If it’s just fish I think it’s ok. If it were coral, don’t think they would be too happy with you.

I took the few coral and put them into my other tank.
