Hey all I am in the planning process of my 180g. First and foremost I need to decide on the substrate. I am leaning towards florite as it will not alter the PH. I am trying to decide if I should do two inches with a one inch samd layer on top or if I should just go with three inches of florite. I would like to achieve a carpet effect in some areas. Which would you say is the best to achieve this? I am open to other suggestions as well. Thank you all for the assistance.
