Before I had a coil denitrator, I had to do biweekly water changes to keep the nitrates below 40ppm. Now I do water changes once a month, & they never get over 10ppm.
I should really have a dedicated pump for the denitrator. Right now I just have a Tee off of a rena filstar cannister. Even with the valve full open on the top of the denitrator, I only get 1-2 drops/sec.
I am not sure what type of pump to get. The water going thru all that tubing creates quite abit of resistance to flow. Also the denitrator sits on the floor, & the top of the tank is over 5' tall where the return is to the skimmer.
