UV Sterilizer....yes or no

[Retro Reefer]

I run one periodically if needed.. good for quickly clearing up water born algae or bacterial outbreaks.

Purchased one after my last velvet outbreak that took 3/4 my fish. Like mentioned before, get a good one. Run the flow slow if your concerned with pathogens. Works great for me. Yes ultra clear water and not a sign of ich or velvet for more than a year and I have added new fish. I dose Vinegar and no issue keeping my nutrients low so it’s not killing all the good bacteria.

Thats the plan. Nice and slow.

I love keeping one in the closet, to use as needed.

The key is getting an oversized one and run it slow (about 200 gph). I run mine 24/7 and havent lost a fish since. Downside was it heated up my water pretty good where I had to buy a chiller...I dont have a mandarin goby but I seem to have a nice copepod population, I see a decent amount in my filter sock whenever I change them out.
