What is my nitrate level?


Recommended Posts

Get a titration method test kit like Salifert for accuracy. Colour changes are a headache to judge esp. in poor lighting and the state of your eyes! :)

To me it looks like its somewhere between 25 and 50!

What kind of filtration system are you having now?

OVerflow system with dry/wet bioball .. know this is no good.

Was advised to remove all my bioballs and biorings. See if this help.

mg/l is PPM .

Hi Spider, how u manage to make ur tetra color chart so clear? If u compare the pic from chris, the color difference for the last 3 zone is not obvious. I'm using tetra for NO3 also and my chart is similar to Chris type.

Can advise. thks

I used to have high nitrate after cycling too. But manage to get it down to 12.5mg/l since. Was having problem trying to figure out which zone it falls in. Luckly, 12.5mg/l color is quite obviuos to me. :D

chrislwp,

Don't mind my observation, but isn't the water level in your fuge and sump a little too high for comfort? :)

Haha.. don't worry.. cause I off my return pump already.. so the water is higher.

When the pump is on, the water is ½ the sump high.
