pardon me if its a novice question.

i would like to change the scaping for my current tank which holds

Tiger Lotus & Hairgrass

the problem is that i have ada power sand beneath the aqua soil and the roots of the plants have clinged on tightly to it. i want to minimise disturbance to the power sand & aquasoil as much as i can.

want to keep the power sand compact beneath the aquasoil so as to minimise any nutrients lost if any for the next scape as my tiger lotus has already took up 1sq feet of the tank. if were to just up root it the unsightly white coloured power sand gonna dominate the aquasoil

how should i go about doing it ?
