clumping turns to mud. yes well all clay aquarium substrates are dusty. Have you ever washed fluorite?

Depends what you want to do plant and care wise.
The more light, the more demands a plant has (were algae isn't as limited)
10-20 Watts wpuld be a good area to be in. 20+ is less limiting in what you can grow, but the plants require more nutrient uptake.
