Halimedia turned white overnight
Hi all,
I've got a slight (I hope) problem. In my 75 gallon mixed reef tank, I have several areas of Halimedia. In fact, yesterday I was taking some pictures of the tank and all of the Halimedia was nice and green. This morning I woke up to a cloudy tank and while looking around to see if something had disturbed the sand bed, I noticed a large clump of Halimedia that's turned pure white overnight. I have no idea what may have caused this or why it would have turned the water cloudy. Any suggestions or advice? All corals appear to be happy and have full polyp extension. All clams also appear happy. I'm posting this as soon as I noticed this issue so haven't tested any parameters as of yet. I'll be doing that next. Alright, test results are also off, here they are. Ca. 380 I try to keep it at 425 Alk. 5.4 dkH!!! I keep it at 10 dkH pH 7.4!! pH is usually at about 8.3 I just tested pH and actinics have only been on for about 20 minutes. Day lights aren't on yet. That could explain some of the low pH reading. Ammonia undetectable Nitrites undetectable Nitrates undetectable Sg 1.025 mg 1225 I'll be dosing for Alk and Ca. Hopefully this will get pH where it's needed too. Any and all suggestions or explanations as to how this happened would be great!! |

It didn't go asexual...may have went sexual. Although I didn't think Halimedia did that. I will be removing it from tank, at least the white clump of it.

Halimeda turns white at tnight and back to green when the light go on. If they don't, they must be dead. Not sure about water turning cloudy. May be a an independent event from halimeda.

My halimeda, before I pulled it out, would become much lighter in color overnight.
However, my water was never cloudy as a result.

LOL I'll say it once again....it's NOT Asexual. It's SEXUAL. However, I do see that Halimedia can indeed go Sexual. I wasn't aware of that. Kar, thank you very much for the link. It seems I have read that link numerous times and have somehow missed that part!! Thanks again.
