When cleaning my gravel yesturday........

[Rodders]

I pushed my gravel cleaner right through it so it hit the glass at the bottom and this massive ploom of 'stuff' got sucked up. I did it a couple of times and the same thing happend.
What is this?? is it the bacteria that grows in the gravel or just general rotted down things

same thing for me
i'M not sure what it is. Might be some kind of algea or bacteria, or maybe just dirt...

most likely just dirt/poo/plant leaves/anything else that is decaying in your tank.

At least you know you are using your gravel cleaner correctly.

All you are doing is removing the muck/silt/sediment that collects in the gravel.

It consists of fish excement, bits of food, plant matter, particles off decor such as bogwood, in fact anything that can that can decay or break down.

This is why it is a good idea to use the gravel cleaner.

It is advisable to be carefull when you have eels and some types of catfish that bury themselves to prevent damaging them.

I tend to try and steer clear abit around plant roots to prevent damaging them too.

Keep up the good maintenance.
