GSP vs Xenia

[jeremyjoslin]

I love GSP and wouldn't mind it taking over large parts of my large tank. Introduced xenia several months ago and the GSP started dying off. I also moved some rock work around that time and changed lighting around the same time.

I'm assuming alellopathic warfare could be a cause? My xenia colony has grown to about 2 sq feet over 5 months. Dense.

My RBTA also seems to be effected. Nothing else in the tank is effected.

I'm considering running ozone in the near future. If this is alellopathy, would ozone (dependent of any carbon I may or may not run) be expected to cure this?

I would run some carbon to be sure.

I don't run carbon and I have a densely populated tank, I haven't had any noticeable allelopathy problems. You could try running carbon but my guess is it's something else, I just don't think allelopathy is that dangerous IME.

What do you mean by "you changed lighting". If your gsp is getting too much light it will die. I don't believe it has anything to do with adding xenia. IMO it sounds like you "light" shocked your corals.

Have my GSP with pulsing xenia, blue Xenia, and a couple BTAs and have never had any problems. This particular tank is 15g with only small 3" bag of carbon stuffed in the overflow every so often. I would look in to your placement, lighting and flow. Also, how often do you change water? Any trace elements? I ask because it could be possible, with the explosive growth you described, that the Xenia quickly depleted certain elements in the water and outcompeted your GSP enough to effect the health of the colony.

I never had a problem with GSP and xenia all over the place in my 14 gallon BC. If anything the GSP suffered, although I started dosing nitrates (very low fish load) and cleared up that issue. Do you have very low nutrient levels by any chance?

I converted an AI Sol to a Vega... visible light actually seems less, but I'm assuming PAR is pretty close. It's been months now with no improvement.

Trying carbon for last week. No effects yet.

I think you may be addressing something important. I don't do much water changes. I tend to skim wet and ATO with some salt added to ATO to keep salinity constant. There definitely is a proliferation of xenia which could have depleted elements. Will adddress with water change.

I've had GSP and pulsing Xenia on a rock that I took out of the tank to clean my sump, put it in a bucket and forgot about it. 2 days later I found the rock that was not even in water, put it back in my tank and everything was fine. Both of these are bullet proof, and will spread faster than wildfire.

Yup... That's what makes this so odd.
