NO3 result Sera vs Salifert

[letdoit]

My coral keep on dying after bought within 3 weeks.

Tested Po4, MG , Ca , No3 , NO2, etc etc.

Now i zoom into NO3 part first,

Using used Sera NO3, result between 5 to 10 mg/L

Someone said Salifert very good. I don't believe, the result should + - 5 to 10 the most. After a few mths , i decided to buy a try, damm expensive,

WOW, above 100 mg/L (100ppm)

Today result for NO3

Sera = still between 5 to 10 mg/L

Salifert = more than 100 Mg/L

:eek:

Does anyone know which brand gave more accuary?

Does anyone know any other brand gave better result?

by the way, if No3 more then 100 PPM, my fishes should be dying too right? but my fishes very good le

[bryanong]

Not neccessary fish will die. Some fish can survive. I feel that Salifert should be more reliable. You should try to do at least 40% water change. Maybe you can try to test both test kits using pre-mixed salt water and see e difference. Just my 2 cents.

Anyone used the test kits from Aquarium Pharmaceuticals? Are they accurate enough?

but the result is so BIG different...

One of them gave total wrong answer, but i not sure which one,

BUt for sure, i try big change of water. 25%, tomorrow 25% again, then hopefully friday NO3 drop, if not 25% again...

Now i understand alot from this website abt NO3 test kit

My no3 very high oso. Corals and fish surviving. But mainly corals need cool water. Do u use a chiller? This is very important if u keep corals.

aiya, with the kind of discrptancy found, its very easy to verfiy....just get a new salt mix or buy a pack of NSW...then test....even with tap water, the reading should not exceed the 100mg range....

anyway, my personal experience with Salifert found the results to be quite inconsistance between batches and sometime even tests!

used AP. found it to be cheap and quite good

[madmac]

Agreed. API, is very good value for money. I've verified their dKH kits with Tropic Marin and found both to be even.

I've not tried their other test kits. Does anyone know where/who carries their full range of kits.

The new API : http://aquariumpharm.com/ with new logo and new kits.

& their kits : http://aquariumpharm.com/en_us/productCate...ryname=TestKits

Hopefully some sponsor will carry their product... (*hint only* )

my first test kit also Aquarium Pharmaceuticals. Because that time no money, so i buy it. I find it very good but the shop ppl said cheap, no so good and intro me other brand....
