Question about using Stump Remover for Nitrate

[John_A]

Hello I have a 40 Breeder with Hob skimmer roughly 45 Gal total My Nitrate has been testing 0 for a bit so I purchased some Stump Remover to raise up to the 5-10 level I mixed 2 tbsp to 2 cups of water mixed and dosed 10 ml then tested 15 mins up to a hour later Still Showing 0 Should I keep dosing until I get a reading or continue with 10 ml daily till it builds up on its on?

I strongly prefer a purified product like food grade sodium nitrate to stump remover, but yes, if you are confident in your kit you should dose more.

Would you recommend dosing more per day or or dose the 10 ml everyday till I start reading?

More per day. You are dosing a bit over 2 ppm. More is OK.

Ok the first night I added 25 ml it went to 10 and within 2 hours it was back to 0 just wasn't sure if was getting zapped out or what

Yes it will take some time for everything to balance out. When I started dosing KNO3 (stump remover) I dosed extra the first few days until I started getting readings. Then I dosed ~1-2ppm per gallon of system water daily until I was able to stop dosing to maintain the numbers. Now I only dose when I do water changes as that removes the little nitrate I need in my system to maintain my parameters.

Consumption in some way is the only way it declines

Ok this makes sense so I probably need to dose higher until it levels out then dose to maintain that I just felt like I was going to over do it adding so much lol
