Iv already filled the tank and did what u had mentioned and its crystal clear. Iv ordered 2 types of carpet plants but im still undecided whether to do a mountain look as the main feature or just get a branchy piece of driftwood?Would suggest when filling the tank to run water into shallow dish set upon the substrate.
Much less clouding of water this way if you don't run the tap wide open.
I filled my tank half full before planting due to large plant's that just wanted to fold over making planting more tedious than need be.
If plant's are small however,,makes little difference.
