I can't afford a Phosphate reactor and i never even heard of them before. I don't like unknown stuff going in the tank. The only thing that goes in is water and api decholinator, do you think i should add something when i do water changes? and if i do two 25% a week instead of 50% the no3 will be within a safe level and would drop?
Sorry if I'm late on this- have you resolved the issue, figured out whether it was the test kit or your tap water causing the high readings?
Have you ever looked into a carbon bottle? If you're worried about the levels of Nitrate straight from the tap, these are simple and effective, you just have to be sure to change out the carbon regularly and keep a slow flow rate through it. Might be worth checking in to.
