Who uses Denitrators?

[jeffberg]

Anybody out there use a Denitrator and if so what make? Would a Denitrator be detrimental to a refugium? Thanks Jeff

[sir_dudeguy]

I've used a nitrate sponge...just the kent nitrate sponge stuff. Just threw a bag of it in my sump and in a few weeks my nitrates dropped to 0, (didnt do any water changes, and still havent lol). My nitrates are still at 0 too and i use tap water, plus never do water changes...so i'm convinced that it really is helping lol.

I have the smaller Midwest Sulfur Denitrator on a 180. I suppose it could impact macro algea that likes nitrates in a refugium. I have mostly soft corals with two monti cap hard corals in that tank and they are doing great. I have seen no negative impact from the denitrator at all - only positives.

I have a remote deep sand bed (RDSB) in a container in my
sump. The whole thing cost less than $10 to set up. While
they take a few months to get going, people have reported
good luck with them.

Mine is only a month old, so I can't report on how effective it
is.

i have the aquaipure denitrator. my nitrates were 80 (or higher) and they are now at 40, so i there was a difference before i stirred everything up chasing some fish around, which caused a minicycle, but when thats over, i think ill see even more of a difference. they do take a while to get going, but what doesnt in this hobby?

I use the Midwest Aquatic denitrator and it works great. My nitrates used to be over 40 and are now 0. It only takes a couple weeks to see the results.

I have an Aquaripure denitrator.

I first had my display set up with a shallow send bed. I've since configured it as BB and in both situations my nitrates remained at 0.

I just added a Korallin BioDenitrator S-4002 to my tank this past weekend. Too early to tell you if I like it but it does seem to be lowering my nitrates already.

[mcrist]

I just tested my nitrates this evening and found that they dropped from a high of 20-25 to 7 ppm in only 10 days. I am happy to report the Korallin BioDenitrator is doing a great job.

[JStorey]

I use the Midwest brand and it dropped my nitrates from 20 to 0 in my reef and from 60 to 0 in my FOWLR in a little over a month.

We use DIY denitrators at work on some systems, and Ive helped a few customers build the same style ones. They work really well IME.

All I did was take a 3 canister RO unit, hook up a small MaxiJet with flow valve on one end, run a line to the first can with sulfur media, the second can with crushed coral (to bring the pH back up a bit), and the third can with carbon (to help pull out any Hydrogen Sulfide). Test the effluent after a couple weeks- if the nitrates are high, reduce the flow with the restrictor valve, if theyre low- it working! Leave it alone! Its worked well for me anyhow.

[acrylic_300]

Mine is just two tightly packed filter compartments with real slow flow going up one and down the other. It works without any media but it took it about 6 months to really kick in.

The only pain is keeping the flow steady.

[carlso63]

I use the original "denitrator"... a plenum.

0 nitrates, 0 phosphates... FOR LIFE

[Ehaze]

I have a aquaripure, it has lowered my nits from 80 to zero in 1 month.

[Ehaze]

ohh, as for the macro algae, i just restock it every 4 months, its really cheap.

[corals b 4 bills]

I win! I installed a Korallin 1502 denitrator 7 weeks ago my nitrates were 100 ppm and killing things, 6 weeks later my nitrates are and have been zero since. I'm an overloader so I think it's worth the money.
