Substrate - how deep?

Pretty much explains itself really. If you have questions about tank set-ups, tank furniture, (caves etc) chuck them in here!

Substrate - how deep?

Post by pringle » Tue Apr 21, 2009 7:35 pm

Hi,
I am making a new tank and want to put l046 in it.
I want to use a sandsubstrate. But how deep does the layer of sand need to be to make shure that they wont dig out the glass layer.
Thanks for helping!
Best regards
Christian

The zebras won't dig that deep - mine only dig maybe 1 cm max. However the current in the tank is more likely to sweep up and re-distribute the sand more than the zebras - at least that's been my experience.

Reguardless, I'd try to keep the substrate layer thin - it will stay more clean that way.

Sand substrate should be a thin layer you can get pockets of toxins building up in deep sand.

I don't have sand in mine, I have very fine gravel, appox just under 1" deep. Will that get pockets of toxins in?

I think the whole ananerobic, hydrogen sulfide pocket issue is WAY overblown - I have yet to meet someone in real life who has run into a problem with this.

I'd agree - I'm not denying it happens - I can confirm that it does - but its not the massive problem its made out to be...

I've got dark sand in our zeb tank - about 3/4" deep. never had any problems with it.
