Can anybody rate Sera Ca tester?

[kschew1498]

I am using Sera Ca tester and on 3 occasion I got 540, 480, 540mg/l !!!! Cannot be that high right??? So I think it is not accurate! What do you guys think?

By the way....any recommendation? I presume the most expensive one must be the best! hahaha

My friend using Sera Ca test kit too.

Heard that he always get 800+, then come to 1 time 1000.

Later I lent him my Salifert Ca, measured only 550.

[kschew1498]

hahahaha 800 &v 1000.....I thought mine is very exaggerated already.....I think $15+ is down to the drain.....

check the box completely or instructions. even under the flaps. maybe got hidden instruction. like the nitrate one.

Mine reads 600mg/l... going to get another brand to test..

[harrywwh]

Mine keep on getting 320mg/l.........

Somehow I wonder what's the point of manufacturing test kits when they don't work.

It's like selling a car that can't start.

[terryansimon]

maybe its reagents are not accurate under marine conditions.

what's the hidden msg for sera nitrate test kit?

[Virus]

yes.. i wish to know what's the hidden message for No3 test. Coz i always get high reading and i suspect my test kit is spoilt coz my LS is surviving well and i test the No3 to be low when using other brand..

[terryansimon]

I think its nitrate lah. where you must divide by 4.4 or some shit like that.

[Vinoth]

Divide by 4.4 is for tetra nitrate test kit.

[terryansimon]

ah you see. that is what I mean.

maybe it has a hidden message like that too..

[mAriNe_enthusiast]

I see... that's for tetra test kit.

But there's no need to do calculation for sera testkit.
