dying rhodactis

[Garbonzo]

So I'm wondering why everything else in the tank seems to be doing well, and these guys (my fiances favorite of course) looks like they're melting away. The nitrate has gone from 4ppm to .6 ppm and the phosphate has gone from .4 to .015. I'm thinking this might be starving them, but I also started dosing iron, trace, and potassium about the time I started sucking nutrients out of the tank, so I'm wondering if I didn't hit them with starvation, and possible metal poisoning as well.

Thoughts?

Do you know what the rest of your levels are? Alk, ph, calcium, mag. And what lighting do you have these under?

 

[Garbonzo]

alk 9.6 CA 430 Mg 1440 pH 8.4. I have my doser set at 24 points a day, so I wouldn't think there's a whole lot a variation, but I may be wrong...

They are under 2x Radion XR30 G4 pros mounted 14in above the tank on phx14 on 55%

The mushrooms are on the absolute bottom of tank.

My shrooms like nitrate 10-15 and even did well higher. When they dropped below 10 they bunched up and looked mad. The only possible concern with lighting is if you put them at the bottom but right under the lights, it could be a hot spot. I have some Rhodactis higher up and more under the light but I started them out at the bottom and off to the side. I slowly then moved them up.

I can also say that once they like the higher lighting they get mad if you move them to lower lighting suddenly.

Well here's the thing. They have been in the same spot for 6 months and loved it under identical lighting besides for the last 2 months I moved it from 50%to 55%.

 

[Garbonzo]

I moved 1% every couple weeks

Could be a variation of things like too much light, adding chemicals without testing and starvation. That's a lot going on and can definitely cause stress and bleaching. Hope they pull through.
