Maybe a little anaerobic area in your AP system might be beneficial for the plants?

Thanks for sharing the information Dave.

Go huskies! Usually all of the horticulture stuff comes out of WSU, not UW. It looks like it is was added at about half the ammount that causes the rotten egg smell. The next step is how to incorporate this into the RSG filter.

I think that an RSG filter... being a deliberately implemented anaerobic zone... to de-nitrify....would be producing low levels of hydrogen sulphide anyway...

Right, now to see how we can ensure that it is introducing the appropriate ammounts of hydrogen sulphide. And to make sure that it does not endanger the fish.

I'm not sure how you could either measure... or control... any hydrogen sulphide produced by an RSG....

It's just going to happen any way if you use one..... that's just a fundamental part of incorporating an RSG....

But I think the amount generated would probably be small.... after all the RSG is a localised method...

And the benefits mentioned in the paper... are from it being dissolved in water...

There's every reason to suspect that some form of localised anaerobic zones might be occurring in grow beds any way... especially those that are either older... or being pushed to limits of solids wastes....

Yep, maybe you could have one before the beds and after the FT but make sure to aerate the heck out of the water before it goes back to the FT.
