why some reefers have zoas whose polyps refuse to open and GSP that refuses to extend?
I have read many threads searching for this answer.
Of course the first response anyone has is "Well, what are your water parameters?"
After the OP responds then the next series of posts go something like this:
Your nitrates are too low,
Your nitrates are too high,
Your phosphates are too low,
Your phosphates are too high,
Your <substitute your favorite parameter> is too low,
Your <substitute your favorite parameter> is too high,
Your PAR is too high,
Your PAR is too low,
etc.
Not once have I found a response that said " I had that problem too and this is how I solved it!"
Responses always seem to be someone trying to be helpful by comparing the OP's parameters to commonly accepted guidelines.
Well, it's my turn to try to find an answer. I'm not going to report all my parameters right now because I am within all of the ranges that consensus says is correct for pH, Salinity, nitrates, phosphates, calcium, Alkalinity and temperature.
I'm really not trying to be arrogant, I would just like to hear someone else say he had this problem and solved it by doing......... Maybe he did change one or more of the parameters for his tank. That would be good to know. I just hate to create another thread where a lot of speculation is offered, but actual individual experiences are never found.
In my case, the Zoas I have were purchased via mail order. All have been in the tank for two months. All opened when I first received them. Over the course of a week each colony opened less and less frequently and by the end of the first month, all remained closed. I dipped them in Coral RX and Iodine before adding them to the tank. I inspected them with a magnifying glass for hitchhikers/pests and have seen none.Other coral frags acquired at the same time seem to be OK except that any with red coloration look more like rust or red clay than a vibrant red now. Types include acans, favias, chalices, cyphastria and ricordia.
The tank is 125 gallons, It has been running with fish for 10 months. The corals were added 2 months ago. I have feed phytoplankton or reef roids once a week for the past month. I have not fish nipping at the corals. Algae is under control. I have a sump with filter socks, skimmer, ATO. Salt mix is reef crystals. I use RO/DI water, and change 25% monthly. I have two flow pumps pointed towards the center, one on each side of the tank.
Please, if you have solved this problem before, let me know.
