hey guys my nitratws are pretty high and iwas wondering what are some good methods to bring them down? ikno there are some plants that are nitrate absorbing, but most are ones that wouldn't go well with my tank. aquascaping wise. I had an idea of sticking a piece of anarcharis in my hob filter? would that somewhat work?

what are other good alternatives?

Floaters or emergent growth is the best for Nitrate exportation. Atmospheric CO2 is higher and injection is not necessary. When the plants get too thick/plentiful just give them away or export the Nitrate to the trash can. Water Sprite was another that did a terrific job, but it could get a bit wild in a large predator type tank.

well iam dosing with the ei method but im holding off on dosing nitrates and ihave some root tabs and ithink it may be that its raising them. there a lil over 40 ppm (nitrates)

not sure if having high nitrates is necessarily good or bad?

eh.. 40ppm is nothing. :) make sure its not coming from the fish poop and you should be good. Enjoy your tank and worry about something else!

Furthermore, are you sure your nitrate test isn't testing high? You're only 10ppm above EI range. You may need to calibrate it. Forum member, Hoppy, will maintain that nitrate test kits need to be calibrated.

I had nitrates >160 maybe >200 in my dwarf puffer tank. they were breeding like crazy.

I think that people in the hobby generally tie nitrates to water quality much like we often tie water clarity to water quality.

and maybe both of those can be tied to water quality but they don't have to.

that being said, since I don't dose nitrates I do use nitrates as a guide to my tank cleanliness.

What about a simple water change. High nitrates cause lot's of stress in fish, can lead to health issues. Running a planted HOB is always a fun project :)

+1. Nitrates from fish/plant waste, uneaten food, decaying plants and a generally uncared for dirty tank is a sign of poor water quality and poor husbandry in general. Nitrates from intentionally adding them for your plants is an entirely different manner.
