Thanks guys. Just knowing what the problem is makes me feel a little better I suppose. I'm skimming through the massive number of dino threads and trying to make a plan
- I think maybe I'll try Chemi Clean as Vu recommends.
- I'm reading I should stop with the GFO so I'll pull that. I can switch it out with Carbon if that will help.
- I think someone mentioned that increasing water changes doesn't actually help so I'll just keep doing my weekly 10%.
- I'm going to stop the skimmer, increase feedings. I might also start dosing nitrate again. I did it a while back but didn't notice a change so I stopped.
- Should I try to add some chaeto to my sump? I have a refugium chamber that just has a deep sand bed and some live rock in it now.
I'm wondering if I should blow the stuff off the rocks or not before water changes. Anyone know if this makes the problem better/worse/no difference?
Bring a sample by this weekend, I’m in corona and we can post photos of what we find.
There is like a 10% chance i can make it to the SCMAS meeting. If I can I'll bring a sample.
...it’s not a matter of where the came from it’s a matter of the conditions were right for them to flourish in your tank.
Okay I think this clarifies a lot. Seems conditions were just right for this problem to occur. It just happened seemingly so dramatically that I was convinced there had to be some specific cause.
From you moving your tank. Stuff dies when you drained water. It takes time to stabilize. Chemi clean if you want to speed up process.
I guess even moving the tank mere inches can still have a dramatic effect! While I didn't notice any immediate issues in the days after I moved the tank, you're probably right. The stress of draining all that water probably helped create the conditions for the dinos to take off.
The other thing that stood out that nobody has mentioned is zero nitrates and zero phosphates. Corals have to eat; you should have some nitrates (3-5 ppm) and some phosphate (0.03 - 0.05).
FWIW,
Kevin
Yes the low nitrates and phosphates has been an ongoing issue in my tank that predates my current problems. I suspect that was part of the reason I didn't have great SPS coloration. I think I'm going to try and work this dino issue first and then I'll work on increasing nitrates and phosphates.
