Nitrate dosing help

[hawk82]

My nitrates are 0, and im getting some dino issues. I got some Brightwell Aquatics NeoNitro to start dosing, just wondering how much I should start with? Tank is a 40 breeder. Does it matter it does it the day or after lights off?

If you are using commercial products follow their instructions explicitly.

IMO when you dose isn't so important as how you dose. You actually want to use a doser so that you can cut the amount down and spread it out over time.

The bottle says Multiply tank capacity in gallons x ppm increase desired x .1261 = ml of product to add. So 40 breeder with rocks and sand is like 30 gallons. Im at 0 nitrate now, and I want to get to 5. So 30 x 5 x .1261 =18. So add about 18 ml? Or am I doing it wrong?

I would raise it by 1 following the directions. Test to be sure.
I would raise it by 1 ppm a day and not all at once.
What is your po4?

 

[hawk82]

So 30 x 1 x .1261 =3? so 3ml? Got a po4 test kit coming tomorrow.

 

[X-37B]

I get 3.78ml so round up to 4ml.
Just so 2ml and retest then more if needed.
You can always add more and half the recommended dose is safe.

 

[hawk82]

Gotcha, start with 2ml to be safe.
