Aquatic Technology Batch De-Nitrator Operating Instructions

Includes de-nitrator chamber

Dosing pump

Re-circulating pump

Fittings to and from de-nitrator box

Timers for dosing pump and flush pump

Not included in price [fill pump, tubing to and from de-nitrator, bacteria food]

 

Get hosing to go from the fill pump to the input in the de-nitrator box.  You will also need to get 1 hosing to drain from the de-nitrator to your tank or sump.

We can provide fittings to match the input to your pump.  The de-nitrator will have to gravity drain back either into your sump or your tank.  Place it so that the drain opening is above the water it has to drain into.  If necessary elevate it on some blocks. Put the re-circulating pump inside the de-nitrator box so that it is blowing horizontally across the egg crates.   Hook up the tubing and place your fill pump in the tank or the sump and the drain tubing from your de-nitrator box to either your tank or sump.  Use one of the timers for your dosing pump and the other for you fill (flush) pump. If your fill pump has 3 prongs you will need to upgrade to a grounded timer instead of the 2 prong timer included with your package.  Set the time and date on both timers.  Set the flush timer to a time when you will normally be there.  Set it to go on every day of the week.  Set it to go off 45 minutes after it starts.  Set the dosing pump to come on 15 minutes after the flush pump cuts off.  Set it to go off 3 minutes after it comes on.  Manually turn the flush pump on until it fills the denitrator box and is draining back into the tank or sump.  Manually turn it off. Manually turn the timer on for the dosing pump.  Put the suction side in a bottle of de-nitrator food.  Let it run until the first drop of liquid comes out.  This may take 10 to 15 minutes.  Manually turn it off. Place the output from the dosing pump through a hole in the lid so that the food will be dripping into the de-nitrator box.  Plug in the re-circulating pump into a constantly on outlet.  Now your system is ready to go.  Set your timers to automatic and watch your nitrates disappear.  After 2 weeks you can increase the time by one minute on the dosing pump.  You can do this weekly until your nitrates are zero.  Once they reach zero you can decrease the dosing time by one minute weekly until they start to rise.  At that point increase the time by one minute for the next 2 weeks and leave it alone.

It is recommended but not necessary to run the output from the de-nitrator box through activated carbon before it is returned to the tank or sump.  This will remove any residual food not consumed by the bacteria.

We use methanol for the food but ethanol, vodka, or sugar water may also be used.  sugar water molds so it is seldom used.

 

Maintenance:  Every year or two you will need to change your tubing.  Replace the food as it is used up.  Clean muck out of the de-nitrator box,  re-circulating pump and trays as it accumulates.
