WARNING : putting your arms in your tank

Hello everyone,

just wanted to know how true this is :

"When the cichlids turn on their sides, skid across the gravel or rub themselves against rocks, always check the nitrate and nitrite levels in the tank. Certain class of bacteria called the Enterobacteraciae use nitrates as a substrate and converts them to nitrites (maybe this is too much info !) Humans have a rich abundance on the surface of their skins, u also find it in tap water and as soon as bacteria are introduced in the water they will metabolise nitrates. U probably need to take precautions against putting your hands (arms) into the tank too much and also making sure that u condition water properly before u add it in. Another possible cause could be having a filter system in your tank with overgrowth of this class of bacteria."

 

without any research, it sounds like a half truth

 

I was trying to find articles on the web about the subject but could not find much/any info. Most of the articles were about human health and aquariums.

 

yeah, i got pretty much the same results, was just hoping that someone on this forum knew something about this...
