Denitrification...
I'm sure that this subject pops up in waves, but as I'm new to online
forums/groups/blogs/whateveryouwanttocallit... Has anyone had luck with external denitrification filters that don't need to be fed? If so... Can we talk about the design?... Thanks... FYI I'm looking to start a custom 32 gallon reef in a friends house and was just playing with a few ideas on ways to make her life easier... |
Denitrification...
Well, trying to keep a denitrifyer properly tuned, is not
exactly making things easier. Live rock and a deep live sand bed in the tank will denitrify the water. But as for making a denitrifyer all you need is an area for bacteria to grow in a container (usually tubing) where the water flow is turned down low enough that the oxygen is used up.

Denitrification...
Other than testing pH of the water, DO levels, and keeping a nose out
for H2S... Any tips for tuning? I'm trying to avoid the deep sand bed just because of the limited size of the tank already. Maybe it's a stretch but, do you think using live rock or seeded crushed coral/liverock fragments in a container with low water throughput but high internal circulation would increase the anaerobic activity without causing too many problems from decaying organics and aerobic bacteria? Or maybe using a coil of hose before a fluidized sand bed with an aeration chamber before going back into the tank? I'm basically trying to figure out how to minimize H2S production to see if it is possible to use denitrification on micro/nano reefs.

Thanks for the quick relpies Wayne... BTW does your store have a
website? On Oct 27, 2:57 pm, Wayne Sallee wrote: To minimize hydrogen sulfide, you can run it through a aerobic bacteria bed. You can also speed up the flow rate through the denitrifier to reduce hydrogen sulfide. You can also aerate the water exiting the denitrifier, as h2s degases quickly.

Wierd, I tried that web addy on friday and must have typed it wrong
cause I couldn't find it... Got it now... Thanks... Wayne Sallee wrote: Umm yep :-) It's hidden in every post, if you can find it :-) In fact I have two web sites, one personal, and one business.

Has anyone had luck with external denitrification filters that don't need to be fed? If so... Can we talk about the design?... Thanks... "DSB in a bucket" a la Anthony Calfo worked for us in our 29g. Put 10" to 14" of fresh, clean sand in a 5 gallon bucket -- any type of sand should work, even silica-based or pool filter sand, although oolitic sugar-fine aragonite seems to work the fastest. Drill a bulkhead about an inch or two higher than the top of the substrate for the water to flow out from back into your tank/sump. Make sure there's just enough flow over the sand to keep solids in suspension (pre-filter water through poly wool or whatever first to minimize detritus build-up) and advection will take care of the rest. Anthony has discussed this method in-depth on a few of the popular reef boards (reefcentral.com, marinedepot, etc...) and also mentions it in the 2.5 hour lecture video recently posted to the reefvideos.com podcast. Ours was higher than the tank, fed it with hose on a ~200gph powerhead and just let it gravity feed back into the tank. Nitrate went from 20ppm to undetectable in about 6 weeks. Cheap, effective, and easy to set up (or take down if you have problems). FYI I'm looking to start a custom 32 gallon reef in a friends house and was just playing with a few ideas on ways to make her life easier... I heard of a 55-gallon tank being used instead of a bucket (and a LOT more sand obviously), it dropped the nitrates to undetectable in a 2000g display tank at some fish store. |

Russ,
The EASIEST way to rid your tank of excess nitrates is with a refugium and some macro algae. I highly suggest chaeto. Since I added chaeto to my sump my nitrates have consistently been at 0 for over 6 months.
