Yes you can get nitrate reactors but they don't work as well on FW
as they do on sw
The same as a skimmer they don't work great on FW
but are great on sw
I have used every kind of nitrate reactor about from the aquamedic nr1000 to the shuran sulpha beads to dosing pumps with vodka
The only sure way to get rid of nitrate if with water changes 25% twice per week is better than one big 50% once per week
One thing I have found is people panic way to much about nitrates fish can handle much more than we think
I keep and bred my rays in a constant 80-125ppm with no bad effects people will say its not good long term but what do we class as long term my rays are near 8 years old now
