Sulphur denitrator for large setup

[glarior]

want to buy a sulphur denitrator for my two combined tanks which is about 500-600 gallons of actual water. I was looking at the korallin BioDenitrator nitrate filter s-4002 with eheim 1250 pump.

Wanted to see if there are other ones that I should check out within the same price range.

I too am very interested in this. Working with large tanks and a lot of fish controlling nitrates can be fun trying to control without adding anything to the sw setup.
I was looking at the reviews and it seems to be better controlling nitrates than the RO pellet reactors. At the same, the bad side, it bring phosphates back into the tank.
RO pellet reactors control both phosphates and nitrates to some extent. I too will buy something soon, not sure which one.
corydrysdale had one, i should have gotten from him. The LR was perfect perfect with the denitrifier.
the more i review the coil denitifier seem interesting too.

I've run sulphur denitrifiers for years now and can safely say that they do not reintroduce phosphates into your system. But the catch is the bioload you have. These types of nitrate reactors are great for low to medium bioload tanks. What it really comes down to is how much nitrogen you are adding to your tank.

The korallin units are well built and can take a beating. The sulphur pellets last for years and the only byproduct is nitrogen that you have to bleed off. But even that depends on the amount of nitrates in your system.

Here's another unit I'm thinking of trying

thats good news for my ears. Is your tank a reef tank or fowlr? I probably have seen it, i just dont remember. lol

120g sps tank with 9 fish. The main thing to watch out for with sulphur denitrators is your alk. Because you need low oxygen water to grow the anaerobic bacteria, the alk and ph drop a little. Most units come with aragonite media but personally I use only the sulphur media and keep my alk and ph levels up with Kalkwasser dosing.

They are a little like calcium reactors ,time wise, in that you have to watch your effluent drip rate and bleed off excess nitrogen every once in a while. But I've run into fewer problems with this type of filter vs other bacterial filters I've used.

Cory is the dude for this discussion. He did a great presentation at the last meeting.

Cory, that's a serious unit!

What do you do with the excess nitrogen? I ordered the biggest Korallin unit. Hopefully, it will take my nitrates down to zero. Been fighting them for to long....

Wish I would have seen that presentation from the last meeting

Thanks bill.

There will be a port at the very top in the middle of the lid. You'll attach some airline tubing and a valve to this port. During the first few weeks, and especially if you have high nitrates right now, you'll need to check the reactor chamber for air at the very top of the lid every day. Just open the valve until you gassed all the air and then your all set.

How are you going to feed the reactor? The best way is to use an aqua lifter pump and a pre filter. If you want send me a message when you get ready to hook up the unit. Korralin directions have horrible English translations.

Hello, I am new here and reply because I am interested in BADESS (Biological Autotrophe Denitrification on Elemental Sulfur System)

I am interested in the sequel of this story to match with our experiences. I have been true the Koralin guidelines setting up the denitrator and I am not very happy with what I have been reading so I am curious how this worked out.
My opinion not enough sulfur may be used for a 700 gal system and reducing the level to below 1ppm would only be possible when the daily nitrate production is very low. When following the Koralin guidelines I do not see how this could be managed. Maybe a carbon based denitrator can be managed this way but certainly not a sulfur based denitrator. Hopefully I am wrong and can I learn something from your story. Using a sulfur denitrator system, it should be possible to have control over the nitrate level in the aquarium and keep it on the desired level, a big difference apposed to other nitrate reducing or removing methods who are only able to reduce nitrate, not control it.. Thanks.

It works. My bio load is huge. I feed my sharks/eels 5 sardines about 9" long every 2-3 days. I also feed whole octopus, squid and other fish. Ive had about 5-10ppm with out doing anything to the aquarium for 1 year. I finally did a water change, clean the rocks and stirred the sand. I have yet to check the new levels. Ive used about half the sulphur that came with the unit. It was frustrating getting it to work but now its eaay. Hardest part is priming the pump. Im happy with it.
