Garren Posted February 27, 2021 Share Posted February 27, 2021 Agree with Daniel. I have high nitrates and hard water straight from the city. My plants eat up the nutrients fairly fast so I still use EG to supplement. You should be all set. 1 Link to comment Share on other sites More sharing options...
CT_ Posted February 27, 2021 Share Posted February 27, 2021 I'm shocked by how many people have high nitrate in their tap. Supposedly the epa sets the limit to 10ppm. Is there some kind of exception? Link to comment Share on other sites More sharing options...
Daniel Posted February 27, 2021 Share Posted February 27, 2021 I don’t know one way or another if EPA regulations are dispositive for nitrates in well water in rural areas. 1 Link to comment Share on other sites More sharing options...
CT_ Posted February 27, 2021 Share Posted February 27, 2021 Oh good point. They probably only regulate municipal water 1 Link to comment Share on other sites More sharing options...
KaitieG Posted February 27, 2021 Share Posted February 27, 2021 We had a high nitrate well in our first house and had to use RO for drinking and cooking. Happens a lot in rural areas. Now we're at about 4 instead of 40 which makes me much happier. 1 Link to comment Share on other sites More sharing options...
MJV Aquatics Posted February 27, 2021 Share Posted February 27, 2021 I live in the country (central NYS) with a well and a 95 acre farmers field across the road. My nitrates are a bit better now, but back when, in the red with the API FW test kit. I 'invented' a nitrate filter (documented on my blog in 'My Nitrate Fight') by repurposing an API Tap Water Filter (now discontinued), filling the cartridge with API NitraZorb. It works great and I've put over 10,000 gallons through it, recharging with salt water every 200 gallons or so. I make about 45 gallons at a time in the basement for water changes on about 5 tanks. 1 Link to comment Share on other sites More sharing options...
Tory Posted February 28, 2021 Share Posted February 28, 2021 How high is high nitrates? My tap water is hard with 10-20ppm nitrates and I don't have any issues with it in my tanks. But lots of live plants could be a simple solution Link to comment Share on other sites More sharing options...
tolstoy21 Posted February 28, 2021 Share Posted February 28, 2021 Yeah I’d say it depends on how high your high is. Mine is in the 40 ppm range out of the well so I also use a nitrate resin filter much like what @MJV Aquaticsuses (I read that blog post some time back!), except purchased my filter / resin from a water treatment supply company. I think I probably recharge the resin much the same way MJV does. If I were closer to the 10-20 range, I’d not worry about it either. 1 Link to comment Share on other sites More sharing options...

Supposedly the epa sets the limit to 10ppm. Is there some kind of exception? The EPA measure is for NO3-N which is a different measure than what aquarium test kits use. The conversion from 10mg/L NO3-N comes to around 40 ppm NO3 according to an API kit if I remember correctly. https://support.hach.com/app/answers/answer_view/a_id/1000316/~/what-is-the-factor-to-convert-from-no3-n-and-no3%3F- Edited February 28, 2021 by tolstoy21 3 Link to comment Share on other sites More sharing options...

They probably only regulate municipal water I think the EPA limit is there because anything over the limit is known to be a possible cause of death for infants under 6 months of age (blue baby syndrome). How far over the EPA limit that red line is, no idea. 40 ppm is around 8.something NO3-N, so human and baby safe. In my experience as a well owner, the EPA has no idea what my water looks like. So that limit is more informative than anything else. I only know all this cause I went through all the well tests when I had a kid and because my dad ran the township municipal water authority in my hometown when I was younger, so he recommended the well tests when my kid was born, just as a precaution.

My water comes in around 40 ppm nitrates and .5ish nitrite and Ive just been dealing with it. So far I can only get one of my tanks and my pond to bottom out on nitrates. I'm definitely gonna do some research on the resin filter I am a little curious now. Thanks @tolstoy21 @MJV Aquatics Link to comment Share on other sites More sharing options...

The replacement resin isn’t cheap (it’s meant to be a disposable cartridge) but through a little trial and error I found an easy way to recharge it with solar salt. In my setup I found soaking the cartridge wasn’t enough, you had to drip feed the brine solution through it at a slow constant rate, buts that easy to do with a length of aquarium hose and a Ziss air valve. if you ever need more detail feel free to ask.

Koi Posted February 28, 2021 Share Posted February 28, 2021 @tolstoy21 could you post the thread or give me a keyword so I can find it? Before I hijack this thread I'll just ask this. Does it waste water like a RO filter? Ive read somewhere that it takes 4 gallons to make 1 gallon of ro water and I don't think I can stomach waisting that much water haha Link to comment Share on other sites More sharing options...

Works inline like a sediment or carbon block filter. The waste from an RO unit comes from the RO membrane rejecting water and the removed waste. 1 Link to comment Share on other sites More sharing options...
