IS there any way to add more nitrifying bacteria to an exsiting system like you can with a freshwater tank????

Not sure which you actually asking about.

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??????

Any other suggestions????????????

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.

Prior to running ZEOVit in my system my Nitrates sat around 15 to 20. If everything is doing well and you are happy with the colour and growth I see no reason to do anything.
How deep is your sand now?
I'm fearful of the debates that will start with the DSB, shallow SB or Bare bottom if too many varied opinions are given on this topic
Many are now finding that the problems outweigh the solutions when running a DSB.
do you have room to add a section to your sump (if you have one) for a refugium?

In addition to that products such as Cycle by Hagen and Stability by SeaChem do wonders in providing bacteria. The number one way of getting a large amount of bacteria in a tank is time and surface area!

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.

'Bringing bacteria in' will not help. You need to provide more 'homes' for that bacteria by adding more oxygen free zones (ie. live rock, more deep sand bed, plenum, or denitrifier).

Adding one very small piece of live rock will do next to nothing.

try one of these.
