Not particularlyIt looks like it's doing pretty well. I see you have macroalgae in it. Do you run your nutrients high to help with that?
Haha! I had trouble keeping a variety of them until I didn't limit nitrates and phosphates. I think I have 9 different macroalgae and my nitrates are 25 ppm and phosphates between .5 - .25 ppm. (I can hear the gasps of horror now!) The high phosphates are probably why my green bird's nest is a little browner than when I got it but it does have PE and seems healthy otherwise. The softies and LPS don't seem to mind the nutrients at all. I have filter feeders like a flame scallop and feather dusters too and I think they do better with the high nutrients.Not particularly
Nitrates were 10ppm last time I checked, though that was months ago and I’ve never tested phosphates
it used to run at 75ppm, you could practically see the macros grow with the naked eye
You have some beautiful mature colonies! I like that.Reset, rebuild, downsized...

After the loss of my LPS, I started working on the tank again, added this little frammer, March 2017

I knew from reading your thread that your tank is probably the oldest on this forum. I also had read about your ongoing battle with the invasive sponge. I have a purple photosynthetic sponge that is very invasive but I remove its small seedlings when I see it places that I do not want it to grow and I run carbon 24/7 replacing it weekly so that seems to keep it from killing anything. Maybe it's toxins are not as lethal.My tank is still going but I am not sure how long I will keep it up. The tank and me are getting old and like me, the tank has a few problems. Not health wise as it seems to be very healthy but I stupidely put in an encrusting sponge a few years ago and it took over the tank.
It is nice looking and resembles blue montipora but sponges exude toxins and I have to trim it because it covers my corals and when you cut it, the toxins come out as this white liquid.
It immediately kills any SPS. Lps also die but much slower. The stuff also grows over the corals so I do have to trim it often. If and when I change water it grows faster and if I never change water the sponge sucks out all the nutrients so nothing grows.
I am killing it little by little by injecting vinegar into it and it seems to hate that.
Luckily the fish never die or get any diseases and I have way to many of them. Maybe 30 or so mostly smaller, interesting fish.
That blue stuff is sponge.
