Silica Bald spots...

[henward]

ok

in my tank i have bald spots where silica sand has been blown away ... corners mainly.

i am thinking, will planting the plants on the sand stop this form of 'erosion'?

the only fish i have in there that would cause this would be the senegalus.

its only in the front right corner by the wood. or, shall i put rocks around it to stop this ?

any feedback?

EBJD used to do this to my sand. Solution, remove fish :lol:

Rocks are a good idea.

how deep is the sand? if its only 2cm deep i would expect it to happen occasionally

[henward]

yeah its not deep right now, probably 1 inch max in the deepest parts

but generally, thin layer

so will thsi be avoided with thicker layer?

[diver21]

yea. ive got a 2 inch substraite in my planted tank, 1inch daltons aquatic mix and the other a fine brown gravel.

ive only got bristle noses digging under logs and they havnt even gotten to the daltons yet. i guess that if you throw another bag of silicone sand in there the fish will move it around again as they please.

just make it deeper, and then a foreground plant like microfolia will spread well and keep it from eroding. roots are good for that.
