Hi guys.
I have a real problem with my zoa's and before i throw them all out..thought a shout out to you guys might solve the issue.
Lets start with the technical : I have a 4' 240 lt tank with about 50gk of live rock. The tank is now 30 months old. I run an internal and external filter system and I have an internal skimmer. Lights are the 4' igalaxy led's. They come on under royal blue at 8am and eventually go off at 11pm. The whites start to come on at 9.30 and ramp up to 50% by lunchtime and then go off at 7pm..leaving the blues and UV's to go down slowly.
The water tests are as follows ( just done today ) water is 1.025, mag/cal are 1450/400, Alk is 8.9, Nitrate is 2, Phosphate is a little high at 0.1 and iodine is currently 0.03. I run 2 x wp25 jebao power heads.
I run nopox daily and have bags of carbon in both filters.
Hopefully thats all the info required....here goes.
I have a number of zoas and paly's in my tank ( see pics ). The paly's are 100% fine. The zoa's keep closing up on me. First thing in the morning ( under blues ) the zoa's are open and look great. As the day goes on so they start to close on me until they are pretty much 100% closed ( see pic ).
( oh...I'm in the Uk by the way..don't know if that is required information )
I have dipped the corals using a coral dip and very little has come out. A few asterina's but nothing else. No nudi's or creepy crawlies.
I have been given a load of reasons why this is happening from so called 'experts'. From too much white light...too little white light, zoa's are from Vietnam and are rubbish...not enough flow..too much flow...aaaaaaggggghhhh
Can anyone help please.
