I have these tiny grain size bugs on the bottom of my aquarium? Any ideas? They are the size of a grain of sand and greyish in color. What are they, are they harmful, and how do I get rid of them? Thank you in advance!

No they are way too small for a pic I think. They are like little flea like balls that run around on the bottom of the tank. They jump maybe a half inch of the bottom then run around some more. I hope they are harmless they are grey in color the size of a grain of sand and the shape of a grain of sand or flea?

They are probably copepods or amphipods, most the time harmless and even beneficial. Although there are harmful cope/amphipods. If you are seeing large amounts it may signal over feeding or lack of filtration. A large water change will greatly diminish their numbers. As long as they are not parasitizing your fish, I wouldn't worry about it.
 
Break out the gravel vac and suck em all out!....not sure what they are,I've never heard of such in an aquarium.They just might be copepods?
 
Hmmm I do daily to every other day water changes. Have an fx5, 2260, and xl4 filtering a 220 with three rays? If you took a grain of sand made it grey and put legs on it that's what they look like...

But are you doing gravel vacuuming?....none of the things you've mentioned will pull anything out of the substrate.
 
What type of fish are in the tank and what type of substrate do you have?
 
It's a tile bottom there is no substrate for anything to hide in. My current collects all the poop in one spot which is siphoned out daily. My fx5 intake sits on the bottom of the tank in the dead spot so a lot of the poop is collect by that.
