What is this stuff on my substrate?

It looks like a bunch of tiny brown pellets. Any ideas?

Hi Padres1234,

At first I was going to say fish poop but what kind of wood is that in the picture?

I think it's Malaysian driftwood. It sunk all on it's own, but that's what I think it is.

It shouldn't be fish poop, it's a 29g tank with a C-220 marineland canister. That should be enough flow right?

Hi Padres1234,

I think that in every tank has areas where there is less flow than other areas of the tank and 'stuff' seems to settle in those spots. Corydoras do a good job of keeping things 'stirred up' but sometimes that is just not enough. For my 30 gallon (36" long) I run a Marineland C-220 canister filter and had less flow than I liked so I added a Micro-Jet MC450 (450 lph / 117 gph) (discontinued) and my tank has much better flow.

Ok cool. Is it dangerous to my fish?

Hi Padres1234,

If it were me I would spend 10 minuteness and siphon off the loose stuff; like you said it is unsightly. Obviously if it is not removed it will break down into nitrogenous waste and may increase you organic nitrate levels higher than would recommended.
