How to lower Nitrates?

[Midway]

Hi there,

Both of my tanks have high nitrates right now. what are some of the ways you guys keep your nitrates low? or no nitrates at all?

Feed less, change water more often.
Get some kind of nutrient export, for instance: grow cheato in sump and then throw it out or give it away

What do you call high?

cut down feeding, grow some chaeto, run bio pellets. Stay away the bottle that claims to reduce nitrate because I found it is a waste of money.

How long have you had your tank?

what happens if you don't trim the chaeto and just let it grow and get bigger and bigger? is that a bad thing? isn't it the more you have the more nutrients it will absorb?

Mh first tank has almost a year i set that up, the second one was setup back in december last year. My nitrates are reading about 40ppm in one and higher in the other one about 80ppm, i think that's quite high. So some of you recomended cheato. Plus more often water changes. I do my water changes every other week to both tanks. All my other parameter are within good range, its just the nitrates are reading high right now.
