Rust growth killing coral

[Riphter]

I do have a digi, frogspawn and hynophora in there. Reviews say it’s bad for anything stony. Most people say there zoas and what not all survive. If I have to I can put the Pom Pom in a bucket with a bubbler.

Sorry I forgot to put my kh. It is at 9. I can get the mag up no problem. I tested it after a week with no water changes. Temp is 79 - 80 usually 79.7 consistently.

UV units for nanos are cheap. Try that if you have not, you might be surprised.
