Calcium Reactor and Sulfur Denitrator Combo

[Drew Halliday]

I have a large two chamber calcium reactor. Could I add a media holder in between the chambers with sulfur as a denitrator or would there still be oxygen present?

The reactor doesn't remove O2, so the issue is the relative flows needed.

So the problem would be that the flow could not be controlled independently without playing with the ph? In a Sulfur denitrator is it primarially the breakdown of organics that depletes the oxygen levels or is it the oxidizing of the sulfur? What if there was a bypass loop around the denitrator. To aid in controlling flow? What if I added bio pellets in the media chamber to help deplete oxygen if the calcium reactor pushed too much flow? Could I reduce the sulfur media if the flow is too slow so that H2S is not produced?

Would there be negative effects of adding bio pellets to reduce oxygen levels? Maybe fouling?

This sounds all very complex and prone to unexpected problems. It might work, but I predict it will not become the next must have reef device. lol

Yes if I have to mess with flow around it it would be easier to run another dosing pump.

I will try with the bio pellets and sulfur in between the reactor chambers and see how that goes. No matter the oxygen levels we should see nitrate reduction from aerobic or anaerobic break down of the bio pellets or anaerobic oxidation on the sulfur right?
