UV Sterilizer - Should I get one and suggestions?

[ricksmithsdca]

So I was noticing brown diatoms appearing on my sand this weekend. My aquarium is fairly new but with established rock. I just added my clownfish pair. I know diatoms (aka brown algae) are normal but should I get a UV Sterilizer for the long term control of water quality? If so, which brands/models do you recommend? If not, why not? This is my first saltwater tank so I would love insight from those who have more experience.

I have one for each tank I have just in case. I've had to use one for a Dino out break once. I also have a generator just in case, haven't had to use it yet. Better to have it and not need it, than need it and not have it.

So do you

I have one for each tank I have just in case. I've had to use one for a Dino out break once. I also have a generator just in case, haven't had to use it yet. Better to have it and not need it, than need it and not have it.

So do you have them piped in but not run them?

No they go in the sump (IM AIO tanks). Forgot I used once to clear up bacteria boom on new tank too.

Ah, so yours go in the sump tank. Do you have a model I can look up?

They're made by Innovative Marine (IM) for their AIO tanks. They come in 2 different sizes for the 2 different size AIO sumps they have. Unless you have a IM AIO tank what I have won't help you.
So what is your Aquarium? This will help with recommending a UV sterilizer for it. Also you have to decide if you want to run it all the time or just when needed. I know that last statement is confusing. Let me try and simplify it a little:
Some reefers run UV all the time with a very slow flow rate through the sterilizer- This kills waterborne bacteria, algae and pathogens(think Ick). This slow flow can kill copepods as well as other stuff in the water corals feed on.
Some reefers run it all the time at a fast flow rate through the sterilizer this kills just the waterborne bacteria and algae(dino's are algae) but not the pathogens,etc.
Some reefers(me) only use it when needed- Dino outbreak,bacteria boom,green water(waterborne algae boom).
Waterborne bacteria are not nitrifying bacteria-good bacteria.
The above is very simplified and didn't even hit on the advantages and disadvantages of each.

I run a green machine in my sump 24/7.. do I think it’s the most effective uv?? No not by any means... do I think it works...? No clue lol it’s plugged in it should be doing something hopefully!

That's funny, thanks for making me laugh.
