Can algae be stop if i put some sand (quartz) on top of the media ? Either if the algae is not yet born or it is there already.

I don't really find sand to be too useful in creating a drier soil. It seems to just clump together when wet, holds moisture, and doesn't dry too fast.

If the sand was sitting on top of a soil that is being kept wet enough to grow algae in the first place, then the sand would just retain as much water as the soil underneath and not contribute much to the problem.

I grow Red Mangroves, and their pot has a layer of sand on top of soil (To replicate the conditions of the beach). I keep the 2 gallon mangrove pots sitting in a few inches of saltwater and the top layer of sand grows lots of algae.

I will see, maybe will work, if the algae are not many. You are talking about the slimy type ? I have the ones that are like moss.

2 days with top watering and no algae. My humidity is around 80 %. Today i started tray method, to see if the algae will appear around the quartz or beneath the quartz. They can appear around the plants, i don't mind that, but i don't want all over the pots.

I've put silica around the plant and soil that the plant is in, and have had success with controling it. Jimbok3

Well, i have a quite coirse type sand at the top layer of all my cephs to keep the crown dry, and there is absolutely no algae!

I think its likely because the soil is 50/50 sand/lfs,
