My Anubias Barteri has a rhyzome with brown portions

Ok, I never payed attention to my A. Barteri but I already noticed some brown small portions on its rhizome when I bough it. Today, its not yet dead, its still growing roots and new leaves appear. Is this a treat?. If so, is H2O2 a solution?

 

Some of the rhizomes on my anubias are browny olive green, haven't given it much rhought. Are the leaves of the plant healthy?

The leaves are healthy but covered with calcium deposits but I fixed the Calcium deposit problem by blocking some of light coming from my LED. The rhizomes were almost "rotting" but not in an "anubias rot" kinda way. I know what an anubias rot look like because my A. nana was infected before and I cured it using H2O2 solution.

 

Any chance we can get some photos of the problem?

Just curious how you corrected a calcium deposit problem with your LED?

Its the light it emits. I just blocked it with floating plants and I think the WC also helps to supplement CO2 in water column.

Here's a pic. The plant is always like this. the plant is growing despite of that.
