Posted	Pulsing / coral
15-07-2006 13:50 by drummerduck	Part of my pulsing became un attatched from its rock over a space of a couple of days..... its now lost somewhere in the tank? Why would this happen... the other pulsing is still attatched and ok?
15-07-2006 18:29 by Penny1	hi i presume you mean a pulsing zenia if so they tend to grow then split into seperate parts and spread
15-07-2006 18:31 by drummerduck	yeah, this didn't split, just slowly came lose, hung on by a thread then went?
17-07-2006 08:47 by Alan	What are you testing it sounds as though the carbonate hardness may have dropped I have seen this before and the carbonate hardness was the problem.
17-07-2006 14:03 by drummerduck	how do i resolve this??
17-07-2006 14:36 by Alan	Get a good buffer and increase the carbonate hardness then wait and see what tests have you done so far to try and identify the problem?
17-07-2006 19:47 by drummerduck	just the normal, nitrate, ammonia, nirite, PH and Phos. thats all the test kits i have. everything ok. Nitrates always 30ppm everything else 0 or very very low.
18-07-2006 10:28 by Alan	You need to test Calcium and carbonate hardness as well these are just as important if not more so than the others. Salifert kits are the best you need one for calcium and one for carbonate hardness. http://www.stm-shop.co.uk/acatalog/Online_Catalogue_Test_Kits_4.html You will also need a calcium and carbonate hardness additive a 2 part solution would be best reef marine are quite cheap and look as a good budget option. http://www.stm-shop.co.uk/acatalog/Reef_Marine_Additives.html If you have never measured calcium and carbonate hardness I am 100% certain this is your problem when these become severely depleted coral skeleton will start to disolve as you are seeing with your pulsing coral becoming detached. Once you get your calcium and carbonate sorted it should re-attach with little difficulty and recover.
18-07-2006 19:42 by drummerduck	i add calcium to the tank one a week? Is that not the same?
19-07-2006 09:30 by Alan	carbonate hardness is different but if you are adding calcium you should definately be measuring it. I suspect then that it is carbonate hardness that is your problem. Carbonate hardness is as important with corals as calcium with out sufficient carbonates coral skeletons will not grow properly and may break down you mention you have a lot of purple algae growth this uses carbonates at an alarming rate.
19-07-2006 19:16 by drummerduck	oh right!!! Will see about sorting that friday! Cheers Alan.... top fella... again!
