Corydoras substrate in 10 gallon

I am looking to replace my substrate in my 10gallon...The sand I currently have is very fine and it is going up into my water and clouding it up every time my Corydoras move around fast...which is pretty much constant as you probably know.... I am thinking about switching back to gravel..I need to get a new filter because the sand has messed it up bigtime...Would a river rock type of gravel be ok? I don't want to hurt my corydoras...But I am pretty annoyed with sand ATM. What type of substrate are you all using with your corydoras?

Assuming your corys are one of the "average" sized species, like the Peppered or the Bronze, a small gravel substrate will work provided it does not have sharp edges. Regular "natural" aquarium gravel is usually OK.

Interesting about the sand. I have two tanks with playsand, and both have a dwarf Cory species in them, they do well over sand. Was it sand or detritus being stirred up?

I would go to your local LFS/fish dealership and get some of this-


despite the label, it's totally inert and perfect for freshwater.
It's also a large sand, with grains about 1mm in size. All it takes is a quick rinse, and it works perfectly.

I consider it a compromise between gravel and sand, and it's cheap.

They are peppered corys. The sand is very soft and sort of powdery..It was ok until I got the corys...I think they must be kicking it up or something..?I have had the corys for a few months now...Not 100% sure if it is detritus or the sand...maybe a little of both? My filter is now messing up on me as well...not sure if it is the sand or just a crappy filter...It is only 5-6 months old.Maybe I should replace the filter and see if it helps first? I am not really sure what to do...

I have 8 tanks..This is the only one I am having this sort of issue with...This tank has been up and running almost a year now...I use the same type of water conditioner and tap water and cleaning routine on my other tanks.The only thing different with my other tanks is the substrate.....I use gravel for my other tanks...



Despite the nasty cloud of my water my betta and my corydoras are acting normal.I dont have a full test kit but my ammonia is usually always at 0 when I check it.

I will see if they have this. I like the idea of having a dark substrate.

The fish probably don't care. But that is quite something else to look at. As you other tanks are OK, changing to gravel would presumably work. Could be a combo of filter and sand though. Is there a strong flow from the filter?

is it possible you have too much water movement? It can keep the sand from settling.

Is it aquarium sand, or did you go out and buy craft sand? Or terrarium sand?

My filter is baffled because my betta has really long fins..There is still quite a bit of movement though but not so much that would cause problems I don't think......Didn't want to get rid of the water movement all the way...just enough so it didn't push my betta around. I upped my water changes to 2 50% a week and it didn't make much of a difference... ..in fact..it just gets worse when I start moving things... So I went back to 1 50% a week..Was just checking to make sure a smooth gravel would be ok for my corys..I don't want to hurt the little guys. They're very cute. I just want to find some solution to my sand storm of a tank eventually.haha
