Found out one thing interesting. It seems like having a deep sand layer makes a huge different in addition to the reactor. I originally had a 3 inch sand layer and recently made it about 5 or 6 inches and after a few weeks my nitrates dropped even more with less flow though the reactor. I'm running about 20 gallons per day, and dosing 12 ml vodka and hovering at 15 ppm. Zero slime on any filter socks as well.

And for my smaller 70 gallon my nitrates are at roughly 5ppm. And I only dose about 7ml per day. I also have zero slime and only clean filters about every other week.

So the reactor works great but pairing it with a deep layer of sand helps take some load off the reactor abs prevents slime build up.

anyway we can incorporate this into a water change system? I have any where between 8~22 pm no3 in my tap.

in my case (living in socal) making 65 gallons of ro every week would be a bit rough unless i find a unit that's extremely close to a 1:1 ratio and this seems like a cheaper alternative.

I cant exactly say if this idea will work but it may be work a shot. In order for it to work you'd need ample outside room and a pretty steady outdoor temp. Pretty much it would have to be consistently from 100+ gallons ( or 2 55 gallon drums connected) and attached a reactor to that and let it run for a week it should in theory drop your NO3 to almost zero. You could even make mini hydroponics design and incorporate some plants to really drop your NO3 levels to zero. Then when your WC time comes it would be a matter of pumping it out into your tank and refilling the barrels to cycle for another week .

You might even be OK just putting a reactor on your tank. Depending on your stocking levels and tank size you might be able to build a oversize reactor and run it pretty aggressively and do smaller water changes and let the reactor drop your nitrates down in the tank gradually. and hold them low. My guess is you should be able to hold the nitrate levels to match your tap or just above them. Worst case you can build the reactor to fit somewhere near your tank and if it dosnt work out after a few weeks then you can try the barrel system.

If I really run mine hard I can drop my NO3 levels at 10ppm per day , but the filters are a mess and it tends to go into swings so ive learned that running less water seems to be effective over the long run since the output of the reactor is less than 1ppm NO3 and produces zero slime.
