My local aquarium store told me to let it sit and the levels havent changed. My test kit tells me to do 25% water changes. How can I best get rid of Nitrate. When I mix water what chemical do you think I should use to detoxify?

if the water you are using for water changes have nitrates in them I would find different water. I use a ro/di unit for my water topoff or water changes. i personally feel the water changes are the best way to lower nitrates. somtimes it may take several changes but it will lower as long as new water is nitrate and amonia free. i hve never used chemical detoxifiers but maybe a nitrate absorbing meterial would be better. it would be removed instead of detoxified.

half a cap of Prime normally turns nitrates to Zero...

RO/DI Is the way to go NO chemical treatments ever! it leaves to much guessing what could still be in there. RO/DI Removes everything then i just put the elements I want back in. Starting with known good source is the best advice you will get here. Also there is a unit called a nitrate reducter or reactor. A refugium is a natrual way to reduce your nitrates and add benificial life to your tank!
