![]() So i have a question for all you expert reef keepers, How does one get more nitrifying bacteria??? Or increase the break down of nitrates????? I have 2 lbs per gallon of live rock and i do, do regular water changes about 20% every other week. IS there any way to add more nitrifying bacteria to an exsiting system like you can with a freshwater tank????

![]() You could try something like a coil denitrator. If you do a search on here, you'll find a few threads.

![]() The natural population will tend to find an equilibrium based on available ammonia and nitrite in your system. anaerobic zones need to be established to enhance the de-Nirating bacteria. Like a coil denitrator. the best way is to set up a refugium or use a product like ZEOVit, Fauna Marine, Reef Refresh, or Elos Purist. All of those systems will create nitrate and phosphate bacteria.

Nitrifying bacteria is the type that converts ammonia to nitrite and nitrate. This is the type that is typically discussed in freshwater tanks and as already stated, will multiply to an equilibrium level with the ammonia output of the bioload. You cannot simply add more nitrifying bacteria to a system without supplying added ammonia to support them. Denitrifying bacteria on the other hand, breaks down nitrate into nitrogen gas or nitrous oxides in the absence of oxygen (inside live rock or in deep sand beds). Generally maximum denitrification capacity in tanks is much less than maximum nitrification capacity, so we usually see a gradual buildup of nitrates. I'm guessing that this is the scenario that you are asking about... Apart from the obvious like increased water changes, increased skimming, decreased bioload, and decreased feeding, some other ways of managing nitrate are: increasing sump/refugium/LR capacity, adding a plenum to your system, or installing a denitrification system.

![]() ya my tank is about two years in the running and a good amount grown in with corals (sps). Just when i test the nitrates never drop below 20ppm. Everything is fine and still getting very good growth out of corals. My next question is if everything is running good should i really be conserned??? and yes denitrifying bacteria is the one im taking about.

![]() Maybe Adding some more sand to my reef to create a more low oxygen areas to house denitrifying bacteria might help??????

Here's an interesting article, explains how you need to starve your water of oxygen somehow, before the anaerobic bacteria will form and start turning nitrates into nitrogen gas. This seems like there would be less chance for detritus buildup than deep sand bed as well. |

![]() I have a 1 inch bed up front but my watchman goby and my tiger tail sea cucumber have moved a nice 2.5 -3 inch bed towards the back. My tank has a 37 times turn over rate. I dont have a sump at the currant momment. I do however have a mangrove groing out of the back of my tank. detritus doesnt seem to build up on rocks, but as a precaution when i feed i use a baster to blow everything in to the water column to be picked up by my skimmer. The other thing i was thinking was maybe adding a small piece of new LR to bring some new bacteria in? Any thoughts??? when i say small i mean small. I just dont want a cycle to start and screw my corals over.
