hi..question about No2,Ph,

[jtsojt]

i just bought those test kit to measure my water.and it show..the no2 0.3..and alk is around 1.7 to 2.8 and my ph is 7.8 ..and for this ph is it too low or high..cause the guide not very clear..can someone help.

What is the brand of the test kit?

What is the brand of the test kit?

for no2 is tetratest and ph and alk is red sea

[jackywongto]

i only know No2 needs to be zero

PH best is 8.2 (magical number) but can be from 7.9 - 8.3 The key is to keep it as constant as possible.

alk - I am not too sure what your test kit is measuring. is it KH (carbonate hardness)

should be between 8 - 12 dKH ideally.

The higher this is, the less PH shifts your tank will encounter.

hope this helps at least a little.

Are you keeping just fishes ?

Don't worry about nitrites. Your primary concern should be of ammonia. NO2 can be hundreds of ppm without killing marine fish.

More on kH. Think your kH test kit measures in meq/L, simply multiply the reading by 2.8 to get dKH.

Please go read up on tank cycling process. there're quite a few pinned threads for starters to read up already

hope it helps

ok.thanks ..

I don't really agree, ammonia and nitrites should be completely zero, please bear that in mind.

Any trace of NO2 can kill your live stock in the tank.

The one that will not kill your fishes is Nitrate, not nitrites.

Please cycle your tank completely before placing any livestock in.

NH4 --> NO2 --> NO3
