I have a 29 gallon tank with like 20 pounds of live rock, 1 hang on tank, 2 inches of live sand and a cpr akimmer. it's been set up for a month now, the ammo is on o.1 but the danm nitrate is sky high with a 110. so what might be the malfunction? i waited a week to see if it would go down but it won't give up. i have been doing like 3 gallons at a time water changes like once every 2 weeks and been placing sponges in the tank from my other 55 gallon tank which were hanging out in my wet dry sump for like a week and ahalf to see if i can get as much bacteria as possible but no joy. :frustrat:
