bomber Posted December 20, 2014 Share Posted December 20, 2014 Hi guys..recently about 2 weeks ago, i brought 5 frags of zoas for a reefer. But after 2 weeks, the zoas is not opening up yet. I havent dip it before and i check for pest and all alot of times in day and night but there is nothing. These are my parameter Amm-0 NO2-0 NO3-0 MG-1200 Sg-1.024 CA-410 PH-8.2 KH-11.2 / 3.99 meq/L P04-0.03 copper-0 temp-26 Im using a 36w full spectrum par38 on them now. The reefer i brought the zoas from is using T5. Could it be that the zoas need time to get use to the LED light? Any bro enounter this situation before? Thanks alot.

SRC Supporter SubzeroLT Posted December 20, 2014 SRC Supporter Share Posted December 20, 2014 Are you using a refractometer to measure your salinity? For me, my Zoas tend to close up when salinity is on the high side (>1.026+) but opens up within a few minutes once I dilute it down.

SRC Member asg Posted December 20, 2014 SRC Member Share Posted December 20, 2014 What about flow? Zoas prefer low to medium flow Quote 子非鱼,焉知鱼之乐... (you are not the fish so you...)

ShadowHunter Posted December 22, 2014 Share Posted December 22, 2014 Could your tank be too "clean"? Quote Link to comment Share on other sites More sharing options...
SRC Member TanWeiSongBeck Posted December 22, 2014 SRC Member Share Posted December 22, 2014 Shift your zoas to a low light low flow area first. Until they open up then based on their reaction you shift accordingly Quote Link to comment Share on other sites More sharing options...
SRC Member sanjaypills55 Posted December 22, 2014 SRC Member Share Posted December 22, 2014 In my experience they do best in moderate lighting & flow just enough to move the polyp...but not strong enough to close it.... If any zoas start closing one or heads ..I would move them to another location ...once all polyps close...its not a good sign already...

SRC Member TanWeiSongBeck Posted December 23, 2014 SRC Member Share Posted December 23, 2014 When he refers to feed he means to your livestock. I believe not all z&p feeds. They growth depends more on lighting. Quote Link to comment Share on other sites More sharing options...
SRC Member acewong Posted January 20, 2015 SRC Member Share Posted January 20, 2015 When he refers to feed he means to your livestock. I believe not all z&p feeds. They growth depends more on lighting. But sometimes I just target feed them with oyster egg They seem ok with that.... Quote Link to comment Share on other sites More sharing options...
SRC Member myintkhine Posted January 20, 2015 SRC Member Share Posted January 20, 2015 Sometimes my Zoas are closed for a long time. I think they are damaged and they recover maybe a week or so after. Quote Link to comment Share on other sites More sharing options...
SRC Member Drahc Posted January 20, 2015 SRC Member Share Posted January 20, 2015 Yes bro..im using refractometer to measure the salinity.. Is your refractometer calibrated? I made this mistake on first day and my salinity went up to 1.3++ after i calibrated it. good thing i dont have any LS and just cycling.

SRC Member TanWeiSongBeck Posted January 20, 2015 SRC Member Share Posted January 20, 2015 But sometimes I just target feed them with oyster egg They seem ok with that.... I will agree palythoa eats. Zoas mostly dont. Not all zoas when closed up means they are eating. Quote Link to comment Share on other sites More sharing options...

richard23 Posted September 14, 2015 Share Posted September 14, 2015 Kh might be the problem...a bit high and maybe the previous tank parameters are lower (fluctuation of water parameters occurs)...then zoa might close due to "shock" Quote Link to comment Share on other sites More sharing options...
SRC Member sharonleong Posted July 17, 2016 SRC Member Share Posted July 17, 2016 Manage to solve the issue? Quote Link to comment Share on other sites More sharing options...
SRC Member Xtraster Posted January 22, 2017 SRC Member Share Posted January 22, 2017 Faced with similar problem... my Zoas started closing one by one... water parameters stable... but nevertheless went ahead to do 10% water change and shifted from left side of tank to right side. Then they open up... so far so good for me... Quote Link to comment Share on other sites More sharing options...
