I have a 220 gallon barebottom fowlr heavily stocked .I used to have 20ppm nitrates quite often. I decided to add biopelets in my sump in a media bag . Surprisingly after 3-4 days my nitrates are zero . I tested using 3 diff tests . I don't have any algae in my tank. What's the side effect of zero nitrates?

Without nitrates in your tank algea won't be able to survive, which seems like a good thing other than dinoflagellates or cyano can take over the tank when they don't have algea to compete with.

As understand it, zero nitrates can lead to cyanobacteria and other niusances, as well as algae can’t grow for your inverts/herbivores to eat.
Yes very true, however never assume you have 0 even when the best test kit says it is. Many coral/inhabitants consume nitrate so you could actually have as much as 20ppm and not know it.

To be honest I was not concerned that much .. Mine was stable at 20 ppm . I just wanted to reduce water change frequency from 2 weeks to 3 weeks . Also I was getting some algae My idea was to keep it at 5ppm so added bio pellets. Looks like I may need to cut it down

Because nitrates can build up over time if never checked/tested. That can lead to long-term health issues for livestock. It's better to test, albeit occasionally, than to never test and assume.

I bought teh hannah Nitrate checker that also showed zeroe
If you're referring to the new Hanna High Range Nitrate Checker??? Friend of mine just received his and it's testing WAY different than API liquid and my digital. I'm not ready to trust that meter yet.

Yes correct I got a zero reading first on Hannah I thought its an error . Then I used API and Nyos tester all read zeroes. I dint know Biopellets can be this effective

They definitely do work. They made my water smell funky and they definitely keep the skimmer busy too.

That’s a negative and a myth. It have to be super concentrated up into the thousands of ppm which isn’t gonna happen.

The main purpose in what we changes in a fowlr is too clean detritus and ensure proper salinity levels, not much else. It would be wise to utilize a skimmer. Water changes are not going to stop the build up nutrients which will have no major impact on a system without corals. In regards to algae, there’re are many more factors then an nutrients that attribute to algae problems. Of which water changes will help.

To answer the OG question...I'm not terribly worried about higher nitrates. I worry about zero. The last thing you want is a dino flare up. I'm still in one and it's ugly. Like...super ugly.

On LI too, would be more worried about the other things in the water i forget tds but i think mine is around 130 (nassau).
Try neonitro or seachem flourish nitrogen, just pure nitrates added to the system and nothing else
