Hi everyone, im really new to keeping live plants but seeing as though im looking to get a knew 170 liter tank, i thought i might give it a go (btw, what do you think of the size..it was this or a 205 liter...im a water saving fanatic keep in mind). Just curious, if im planning on getting plants such as java moss etc or really 'ground dwelling' plants, how do i go about cleaning out my tank? Does it mean i have to remove it all in order to clean the gravel? Won't this damage the plants?
