thecloser Posted March 11, 2012 Share Posted March 11, 2012 Out of no where my zoas have stopped opening up for about 2 weeks now. My Sunny D's open enough to get SOME light but thats not saying much and I have had a random brown/gold diatom bloom or something like that all over my sand bed for about 3 weeks now. Not sure what is happening out of no where. This tank is about 8 months old with probably 25lbs LR and 30 lbs LS in a 20Gal Long Link to comment
WrongGenotype Posted March 11, 2012 Share Posted March 11, 2012 Might want to check if you have any pests. I had the same problem and later saw that I had some nudibranch bugging them. Check out this link: Zoa Pests Link to comment
Builder Anthony Posted March 11, 2012 Share Posted March 11, 2012 i just moved a plug of sunny ds from a med flow high light to a low flow low light but they seem to like high flow high light.now this may be because i run a long photo period and algae tends to build up on them,then they close.

mndfreeze Posted March 11, 2012 Share Posted March 11, 2012 the sandbed bloom is key to the mysterey. Check your parameters and post em. Maybe cut feedings back. Do a water change. Don't use tap water. Link to comment
thecloser Posted March 12, 2012 Author Share Posted March 12, 2012 I will be doing the tests tomorrow morning something has caused this massive diatom explosion Link to comment
thecloser Posted March 12, 2012 Author Share Posted March 12, 2012 Nirtrte - 0 Nitrite - 0 Ammonia - 0 pH looks to be at 8.0 Calcium is around 400-420 phosphate looks to be at 0.25 and kH i believe was at 161.1 but could have been 143 maybe Link to comment
Veng Posted March 13, 2012 Share Posted March 13, 2012 Nirtrte - 0Nitrite - 0 Ammonia - 0 pH looks to be at 8.0 Calcium is around 400-420 phosphate looks to be at 0.25 and kH i believe was at 161.1 but could have been 143 maybe 143 kH... that would be impressive. The Phosphate is high, everything else is fairly low, but that oculd be the diatom's eating it all. I would expect some NitrAtes though.. Did you change your water source, lighting scheduel, or feeding recently? Link to comment
wenhamjj Posted March 13, 2012 Share Posted March 13, 2012 I had this happen to me once where all my zoas would not open. What fixed it for me was a good FW dip and then I blasted the crap out of them with a turkey baster daily for a couple of days. After doing this they all started to open and within a week they were opening fully. I would at least give them a good blast cleaning with the turkey baster. Just my 2 cents worth. Link to comment
Cintax Posted March 13, 2012 Share Posted March 13, 2012 143 ppm isn't impressive, its like 8 dKh. Link to comment
thecloser Posted March 13, 2012 Author Share Posted March 13, 2012 so what are peoples thoughts on this? Link to comment
KoolFish Posted March 13, 2012 Share Posted March 13, 2012 so what are peoples thoughts on this? Your test results look fine other than the phosphate. Did you add anything new in the last few weeks? Corals, etc... for example, I had problems with frag plugs not being cured properly and caused an algae bloom and all the corals to look unwell. Look over the last few weeks and see what you may have done differently and added. ...and what is your water temp and salinity? Link to comment
JamesHL88 Posted March 13, 2012 Share Posted March 13, 2012 This happened to my green stars until i found a nudibranch under their rock and plucked them out i think this is the case and the diatoms are an unrelated issue. This happened to my green stars until i found a nudibranch under their rock and plucked them out i think this is the case and the diatoms are an unrelated issue. Or you could be giving them too much light. This could cause the polyp retraction and the diatoms but im still leanin towards a nudi being the culprit. Some of those basterds blend in so good they are hard to find unless you catch them in the act munching on corals. Link to comment
Builder Anthony Posted March 13, 2012 Share Posted March 13, 2012 actualy ill take back my first comment ......i had my first signs of melting.i think it was caused by high salt 28.lowered it w waterchange and sunnys r opening .....mini aussies were starting 2 melt........run high salt? Link to comment
thecloser Posted March 14, 2012 Author Share Posted March 14, 2012 i think my salt is at usually the 24-25 range... even my LR has these brown diatom on it with like fuzz but only on 3 of the big rocks. looks like a brown algae maybe dark green. my Zoas are stretched out as mch as they can to reach for light but they don't open up and the weird thing is, a few new heads of grown during this time. I have my lights on for about 10 hours. Link to comment
Lawnman Posted March 16, 2012 Share Posted March 16, 2012 I would do a nice big waterchange. Phos is pretty high at .25. Other than that all I can give you is air I am clueless. Link to comment
thecloser Posted March 19, 2012 Author Share Posted March 19, 2012 Okay well my frogspawn is barely opening for. Few days now my purple deaths haven't in weeks my 3p zoa apparently unattached itself from its plug and the rest just aren't opening... I even changed my bulbs thinking that was a problem ...

thecloser Posted March 19, 2012 Author Share Posted March 19, 2012 Anyone have a clue At all? I also remembered hanging the carbon but that's about it. Link to comment
