[APD] RE: Mulm accreation in plant tanks
Mulm accreation in tanks with wood is pretty high. Replacing with stones is
a common theme with Amano and several others.
If they use wood, most of it is covered with weeds. Smaller twigs are
better than big blocks. I do not think there is a great deal of differenc
ebetween something hard like Oak vs a soft cedar wood. The Mopani wood is
rock and will not make much.
But petrified wood is great, no mulm there:-)
Some plants that are not trimmed or plants that collect dirt will also make
this an issue. Poor growth also encourages more mulm by leaf losses. Some
fish and snails will eat this plant matter and turn it into mulm or snail
Mulm is not a good thing really except in small amounts in the substrate or
large amounts in a non CO2 tank substrate. Too much can be bad and place a
larger demand on O2 and organic fractions of nutrients which take more time
to become available to plants. Works well in non CO2 tanks, but in CO2
enriched tanks, not so well in general.Things move too fast.
Reminerlization takes some time and less light to work well for plants.
