How high?

[dorbe]

using sera nitrate test kit show it is about 400mg/l ( red color).

Yikes!!! 400!?!?!? Are u sure u got the correct row for yr reading? U mean u used 5ml tank water + 15ml distilled water (correct me if i'm wrong, too lazy to lookit my own lousy sera kit...) and u got a deep red reading?

[dorbe]

yeah yeah....

it bright red in color...

afraid it might kill my coral liao

[Tanzy]

Change water! Better find out why the nitrate is so high in the first place.

use nitrate sponge/eliminator...kekeke....tat's always my advice for high nitrate...hehehe becos i dunno any other ways to eliminate nitrate well at least my nitrate level are within acceptable range

IMO...use Sera test kits previously...dun really trust them i thk Sera have to do more R&D on marine test kits...results not so accurate

I'm using Sera test kit, too. The nitrate level of my tank ..... scare the shit out of me. I'm trying to get second opinion from another brand. How about JBL ?

Though, the nitrate is high (according to Sera), my mushroom and finger coral are growing.

I have same problem previously.. But now reduced.. High nitrate corals will still do well, everyone is happy.. I think fishes will be the first to feel the stress..

I think it is the other way round. High nitrate affects corals more than fishes.

my coral is "open" up as usual....and my fish still swim around. it only that one of my tang die today....but if nitrate is high ..all fish should be affected rite??

think i will need to test it again..

Thanks

Best is do partial water change..

[bawater]

not all fishes will be affected, the hardy ones can tolerate up to 500mg/l

this is the level 50% fish mortality is recorded at in studies.

All depends on what kind of fish u keep,some don't tolerate & will die at 50mg/l

corals can tolerate up to 100mg/l but only for short periods*(before they close up & 'mati') & acros can only tolerate up to 10mg/l max

best do a partial water change as everyone said,somethin dead would have raised the ammonia levels- which once cycled will end up as more nitrates , change first then look into the source of the problem.

don't think of the Intepret tablets test kit, i just tried them & i find readings only accurate for FW, a little off for SW(even though it says for FW & marine).

How long your tang been with you?

[kelstorm]

actually, tangs is the best indictator of water quality.. coz they are very intolerant of bad water quality..

is tis generally the case

any other fish tat are sceptical to low water quality?

[dorbe]

wow...used tang as water indicator???

i tot tang suppose to be quite hardy?? and quite ex too...

my nitrate is still sky high.....but my fish and coral still looks fine to me.

prepare two big pack of NSW..just in case, if anything goes wrong
