So I was searching the web to figure out why my zoas aren't doing so hot. I was told to raise my light off the tank or to put phosguard in my tank because that slowly kills zoas.. have any of you heard about this? :confused2:
 
Maybe .....could you expand on "not doing so hot". Pictures will help alot, as well as water parameters.
 
They are receding very bad and not opening.
My Parameters are
Salinity - 1.023
Nitrate - 0 ppm
Ammonia - 0 ppm
PH - 8.0
Mag - 1350
Calcium 390
Alk - 9KH


My Blue tubs

And my Fruit loops

Edit: I have 8 other colonies of zoas and they are doing fine. Im am so confused as to what to do with them. I really don't want to lose them.
 
I've had Phosgard in a TLF reactor on my tank for about a year, so far no problems with zoas. You may want to post a question in the Seachem thread ( the are a sponsor of the club) or shoot them a PM).
I use it because I can pick it up close by( they order it for me) and when I started using it there was some debate on PO4 media releasing some PO4 back it the system, from what I understand Phosagard won't do that. I think that it is aluminum based as opposed to iron, ferric or ferrous based as in GFO

In my tank I've had ALK issues, nearby corals attack and bryopsis problems, but I don't think that Phosgard caused any of that ( alright maybe not changing the media may have caused contributed to the bryopsis ;-).
 
Well i had a reactor on mine and everything was doing great then I was like I have a 30 gallon reef, do i really need this? So I sold it and now my tanks not doing so well.. Everything is alove but not thriving.
 
Looks like it is only affecting some of the zoas

The yellows next door look like they are rockin' so I would not think that it is system wide. Are these new perhaps and acclimating to your system? Have you researched Zoa eating nudibrach at all?
 
If it was a nudi wouldn't they spread to other corals. and None of them are new, they just started closing up one day :( Maybe I should try a coral dip.... ?
 
I wish that I knew more so that I could help. I'll subscribe to see what the professionals say.

About two years ago I picked up some Fruitloops from a member, the 3 polyps never grew stayed and small and were often closed. They hung on for about a year then finally melted away, never found out why they didn't survive.

The ALK seems to be alright. I sometimes double check my readings with a trusted LFS, just to double check the checker.
The dip may not be a bad idea, see what falls off. Look at with a magnifying glass.

I don't know if this is messing with the Blue Tubbs or not, put I had a frag that fell into the sand bed stayed down there for 3 wks/a month. It looked better the the others on the frag rack. Later I moved some more down to the bottom and the blues really come out and grew faster. In my tank they seem to to like lower light and low/moderate flow.
 
What kind of livestock is in the tank? I've run phosguard as well in the past with no ill effects.

With how spaced out those fruitloops are, it looks like something is eating it.

Edit: And at second glance, the first picture of the tubbs blues (at the very bottom), that closed polyp looks to have something on it (possible nudi eggs?)
 
IME zoas can be very finicky, doing fine one day, melting the next. Dipping won't hurt anything, so you may want to try that. That'll be a good time for you to fully inspect them for nasties.
 
Always dip zoas when somethings wrong. Dip the **** out of them. double dose.
 
I have always used coral rx and lugols sometimes mixed together and up to 4x strength with no ill effects. Got rid of a montipora eating nudibranch problem. Also did great on acro red bugs.
 
For Zoas, I think a fresh water dip can be very effective. Zoas are hardy as can be, but their pests will jump off in fresh water. I've only done dips for no longer than a minute or so
 
I think it might be the zoa spiders. I was reading they eat the base first and get in the base to where you cant see them this is the only pest I could have, I dont see any nudis or bugs. I will fresh water dip them and see what comes off.

Edit: Ive always bought some new chems. from the Red Sea line, seems to be helping a little. maybe they've been lacked of nutrients.
 
If it is zoa spiders, I have the fix. Potassium permangenate. If the FW doesn't fix them, send me a pm and I'll share how I've successfully used potassium permanganate to clear corals of sea spiders.

The fisrt meeting of the year, I brought a bunch if different creatures that I had gotten off of corals from PP dips. We looked at all of them under microscopes. It was pretty cool. Some of the spider I brought were still alive and you could see the fluids being pumped through their bodies, and their organs moving. A few had eggs attached to the legs. If you are into marine biology, it was fascinating.
 
Wow that is so cool I would have loved to see that I am super into organisms and what not, marine biology is my goal in life haha
 
Zoa pox and Zoa fungus both seem to be more prevalent during the heat of the summer months.
Dipping in furan-2 is the only thing I have ever known to cure these 2 zoa diseases.
