I'm getting closer to having my 5 gallon tank cycled, as the nitrItes have spiked. Next I know will be the nitrAtes and the cycle is complete. But since bacteria will not get rid of nitrAtes, how do you control them?
Obviously I know water changes will help a bit, but unless you eventually change 100% of the water, nitrates will continue to climb. Will plants help to absorb the nitrates? I have a couple of sword plants, and my duckweed is growing. (I got just 3 stowaway leaves of duckweed when I bought the swords, and now I have close to 20 leaves!) Will these help?
I just want to know how to most effectively keep the nitrates in check once the cycle is finished. I'd rather not use chemical products to 'absorb' the nitrate if I can avoid it.
Thank you all!!
