Sulfur Denitrator: Who's running one?

Just a word of caution, using this special connector never worked for us (actually most of the stuff he recommended didn't work, but that's another matter). I would suggest that you don't waste your time or money with that idea. It gives you a false sense of optimism that leads to frustration and disappointment.
Sorry I can't help on the low pH issue.
Just to drag this one back from the dead.
I have just setup a new reactor using the Redox control method. Everything has been going fine for two days now sitting on ~170.
But this morning the tank has gone all milky. What would cause this?
All fish and livestock are fine with no smells coming from the water.

Nope my Ca reactor is fine.
I am starting to think that the two teaspoons of sugar that I added to the reactor to kick start it has caused it.
It took a day for it to happen which would coincide with the time taken for the water to expel from the reactor at a slow drip.
Does this sound plausible?

It sounds a lot like the calcium precipitated out of solution. I don't know that anything you did related to the sulfur denitrator would have caused it, though. The only thing I can think is that if you are running it like we did, with Ca reactor meadia in the second chamber, you could have upset the balance causing the Ca to drop out. If it is calcium precipitation it's no big deal. You'll wind up with a "snow" all over everything that will go back into solution in a day or so.
If you don't get that snow, it is possible that it's an algae bloom brought on by the sugar.

I built one from plans on Reef Central cost about $50.00 for materials and $65.00 for media. Its only been running for 2 weeks and my nitrates were off the wall now its down to 20 soon I think it will level off at 10 which is my goal
I have been running an H&S 110 for about 6 months it took almost 4 months to really get going.I talked to the people at Finsreef and they said I may not have had enough crabon.So I dosed 1ml of Vodka every other day for 4 weeks.I went from 10ppm to 2.5 during that time at 2 Drips per second.You have to get the drip rate just right until it is set and you don't touch it unless your nitrates climb.I now test about once a month and I am at 0 nitrates.This unit works great and my alk does not dip at all.I use enough crushed coral at the top and my ph coming out is around 7.2 which is not that bad.I just use a auto topoff with kalk and never had PH or alk issues.My alk is aroun 9dkh and ph stays around 8.2.I reccomend using the larger grade media in the sulfu reactor.Just my experience with this unit has been great.It just takes some time to fine tune it.But I think its worth its wweight in gold no more glass algae or algae on the sand all gone.Corals growing like weeds.
controlling my midwest unit via a ORP controller
I am interested in controlling my midwest unit via a ORP controller .. I get the concept but want specifics on using a solenoid valve or two at different or variable
flows . Is it as simple as turning on and off the aqua lifter ? Would you ever have to restrict the effluent line like I do now ? Just looking for the best setup the
first time.

Not sure if you noticed, but the last post in this thread before yours was over 2 years ago. I'm not even sure anyone is still using this method anymore, but I could be wrong.
I know , but some things come full circle sometimes . What would be the newest method now for controlling Nitrates ? I still think a reactor like this just needs help keeping in adjustment
and since I am using one as if was the latest thing. I was reading about using ORP to control but this thread lacked anyone automating it via variable flow .

Bio pellets in a reactor seems to be the thing now
Tony, there are still some people using under gravel filters around here and swear by them. I wasn't knocking you on trying to use this method... was just letting you know it was an old thread in case you didn't notice that.
I think Sid is right though. Bio-pellets, skimmers, and macro algae seem to be the most popular methods to reduce nitrates these days. Usually a combination of some or all of them is the case.
