Never mind the tower...I'm amazed his wife lets him keep a ladder in the livingroom!

Hey PTC,what do you feed your Pirarucu? If it's prepared food can you show a pic of that? That would be one big pellet!!

Hey johnptc,
whats the difference in chemistry (?) between input and output of this thing?

great question...............there have been several threads on fast flow towers reducing nitrATE levels.... although no one can say why or how this would have any affect on nitrate levels.........i have never gotten my nitrates below 20 ppm with what i see as massive 24/7 water changes ( 1000 gallons/day) with no nitrates in the make up water......
so :
1) more bio filtration is good ( think tank expansion as sam the gigas grows)
2) i will be monitoring the nitrate levels in the tank to see if there is any measureable change
do you think any common tests could show a change in one pass.....its about 50 gpm.....not much contact time.
thanks for looking......you input is always appreciated

Nice work John!
You will be surprised how well it works in removing nitrates. Tall wet/dry's do a much better job at consuming nitrates than short wide ones. It will take a while before it removes nitrates. I have a link to the research on them on my other computer but it is DOA right now. Many bacteria live aerobicly and anaerobicly. When they are in an O2 rich environment, they thrive but when the oxygen drops they exist anaerobicly. Their metabolism is much lower in an anaerobic state though. While they are in an aerobic condition, they can still consume nitrates as if they were in an oxygen poor environment; though not as efficiently. Most of the nitrate consumption will occur at the bottom of your tower.
It was stated in the research findings that wet/dry's that were started with water with high nitrates had a much better chance of becoming nitrate consuming than systems that were started with water that was nitrate free.
