Possible use for a denitrator?!

I saw this on ebay and got thinking, maybe i could turn this into a denitrator.
if i employed a slow drip on the intake, filled the lower chamber with sand? Then the higher chamber with deniballs - would i not basically have a denitrator?

Midi- Fluidise Media Reactor -Sand ? Phosphate - Carbon on eBay, also Filtration Heating, Fish, Pet Supplies, Home Garden (end time 05-Oct-08 19:47:09 BST)

I would like you opinoins!

 

when i think about it, i might not even need a drip on the intake. Maybe if i just used a pathetically slow and small water pump that would be good enough?? As im think the compactness of the sand would slow the water rate right down its self??
Slowest pump i can find is 400lph

 

I dont understand your Q. But if it helps, I T'ed off my return line so I could adapt a fitting to accept a R/O size line to connect to the coil denitrator. Luna

 

sorry, i'll try to explain better,

Its basically a dual reactor. What im asking is can this be used as a denitrator?

If the first chamber of the reactor was filled with sand (to harvest aerobic bacteria) and the 2nd chamber filled with deniballs (to harvest the anerobic bacteria) this combined with a slow flow - surely this would basically be a denitrator?

Well Deniballs are quite expensive, so maybe Seachems denitrate can be used instead? I could do with Tangster chipping in with his opinoin
