So I keep battling nitrates. I dont have ammonia problems at all but the nitrates can creep up fast. Its a 55 gallon tank total water maybe 65 gallons. I do LARGE (for the system-15 gallon maybe more) water changes every week to keep it down and its rather frustrating. I was hoping that the reactor would allow me to go at least 2 weeks between water changes. Has anyone used a nitrate reactor? Which brand? Pros and cons? Any information would be really helpful.
