Does UVC Sterilization Light KILL "good bacteria" that controls Nitrates?

UV can only kill what is in the water column which is about 0.1% of your good bacteria so no

No it does not. denitrifying bacteria lives on structures or more precisely working structures where oxygenation is low. Same thing can be said for the nitrifying bacteria as it also lives on surfaces and not in the water column where U.V. can have an effect.

Nobody is able to set up 5 tanks and have all five demonstrate denitrification anyway, so those bac are incidental. lucky when arranged in measurable ways. there are ways of arranging a tank to make it favorable only.

but everybody can set up a tank for aerobic filtration bacteria and have it ready by day 30...even if you run uv and used bottle bac at the same time

aerobes are so predictable.

*if you are meaning carbon dosing boosted bacteria, where we dose a sugar/vodka and boost up resident aerobes then export them for n and p tuning, uv can suppress those.

It would take thorough and large uv to completely nullify carbon dosing, you'll have to try and see. its counterproductive when running carbon dosing, you are wanting happy bacteria dividing x 100000

Speak for yourself every tank I have setup in the last 15 years has a complete ammonia cycle not the partial one that leaves you doing water changes to try to finish it off.

I could be wrong but I think you're confusing denitrifying bacteria with nitrifying bacteria. Nitrifying bacteria (aerobic) convert ammonia > nitrite > nitrate and denitrifying bacteria (anaerobic) convert nitrates to nitrogen gas?

Edit: If I've misunderstood your post then I apologize.

Establishing denitrification is not elusive by any stretch. There are numerous ways to accomplish that goal.

 

[Aardvark1134]

I am not confusing that. If you don't have both types you have to do frequent water changes due to an incomplete cycle. Putting a few gallons of pond matrix or marine pure in a proper location is the key.

You can also put in a cheto farm in your sump.

This was really all I needed to know. Past that you guys are intellectually losing me quickly due to scientific chatter....lol

It’s a yes and no answer. Yes, it does kill, but rate of killing good bacteria is lesser than they are created. So it does not affect the cycle.
