Coil denitrator help

[bmkj02]

I have set up a DIY coil denitrator for the past 6 weeks. Its has about 100ft of RO tubing in it with bio balls on a 125g tank. Its set about 1 drip a sec. Now is the nitrate level coming out the denitrator supposed to be higher or lower than the DT? Mine is coming out higher. LFS told me slower the drip is better???? Any ideas?? Thanks

I appears to be still cycleing. If you still have nitrates at the exit point you don't have enough anerobic batira present. So your LFS is currect in telling you to slow down the drip rate. If it goes to low (drip rate)you will start to smell the odor of rotten eggs (not a good thing). I would give it another 2 weeks before doing anything, if you still have the same readings I would think your tubing has become disconected inside your unit.
