Aquarium Advice Regular
my tank is a little high on the nitrate side i have been reading about denitraters and really don't want to pay $200 for one so i looked up diy denitraters and they are really easy to make for about $20 big difference now i want to know if anyone has used them and if the claims really are true about how well they work. they claim to keep nitrates down after the cycling period at 0ppm if your tank raises at 25ppm in nitrates is this true if so i'm gonna build away......
