SPS - grrrrr - those things make me lose interest in the tank.
Soft corals are doing very well - hard corals, I had them going well for a bit and then summer showed up and the same old pattern I end up in started again.
I'll have 2,3 or 4 months of nicwe growth, good coloration etc - everything will be happy. Then suddenly I'll see RTN start on 1 piece. It will be fully dead within about 2 days - and then the same thing happens to the next piece - and so on.
I'm down to I think 1 stick - this go around it even affected my chalices, which I've never had a problem with. I'm positive its' something I'm doing (or not doing) - could by NO3/PO4 be a problem? yep - it could be. Maybe trace elements? again, could be.
I could run myself crazy trying to chase it down - but I've been there a couple times and it's just not worth it for me right now - so I'm gonna let the tank do what tanks in our house do well. Happy fish, happy inverts, happy soft corals (most of them at least) - and enjoy it as it is.
Shrooms below - doing wonderful (pic taken today). These things were nearly invisible 18 months ago - they were seriously nothing more than a couple greenish specs on that rock.
and below is what is likely my last hard coral - and it's on it's way out.
I'd really love to have one of those "WOW - look at all those crazy growing corals that grow so fast I can't give them away fast enough" tanks - but it's just not something I'm gonna pursue.
We have so many creatures in our tank that are healthy and doing great that I'm just not interested in chasing my tail on what is likely not going to happen.
