Sodium Nitrate

[coolhandgoose]

I understand you post and thank you for your concern. Sodium nitrate is a legitimate way of trying to raise nitrate levels in the tank. Hydrogen peroxide is not like some chemical poison that is going to destroy everything. Now if you pour a whole botle in your tank, yes you can expect the tank to crash. From the research I've been doing so far this is very similar to using an ozonator.
