Silicone and aquarium terracing AND A QUESTION ON AQUARIUM FERTILISER?

Question

i'm planning on using silicone to attach some juwel terracing walls onto my glass so that it doesn't move forward with the substrate and no sand falls around the sides but what i want to know is -----

if you use silicone on the interior of the aquarium will it permamently stay there or can you peel, scrape or just remove it at a later date when you want to change the interior of your tank?

ALSO if you have aquarium soil like seachems flourite soil or caribsea eco soil is it alright to add liquid fertiliser for mosses or any plants that don't have roots in the soil like java fern or will the liquid fertiliser interfere with the tanks chemistry (or somthing like that) ?

many thanks

Answer 1

using a fish friendly silicone sealant is fine and you can remove it later if you wish, you can buy plant fertilizers but make sure you don't over use as it will cause an algae bloom
