Sulfur denitrator experiment

[Delphinus]

Not yet. Randy Holmes-Farley did this article about sulfur denitrators where he showed the chemical reactions happening and demonstrated how the calcium and alkalinity, although there will be some, won't really be a significant source for the tank. However I'm sure it's still better than having nothing.

How did you ramp it up? I'm still running about one drop per 2 to 3 seconds. Could I start opening it up at this point?

I don't have vol3 yet. I dropped a pretty big hint to Santa though.

So ...

5x media volume. I'm using a 4" reactor and my media height is approx. 8.5".

So roughly PI * 2^2 * 8.5 (Pi * r^2, where r=2 because diameter is 4") = ~107 cubic inches

1 cubic inch = 16.387064 millilitres

Therefore 107 * 16.387064 = approx. 1750ml

1750ml * 5 = 8750ml/hour

8750 / 60 = approx. 145 ml/min

That seems pretty fast to me. Am I overlooking anything or should it really be opened up that fast?

I guess that's only about 6 seconds to fill a 15ml measuring spoon. A little more than twice what I run my calcium reactors at (I run mine at 60ml/min) so I guess it's maybe not that far off. Hmmm ... interesting.

Ok so the real question is how much time do I give myself to open up the reactor to that speed?
