I want to change my substrate, I currently have the Tetra Complete substrate and i feel like it's just stopped working none of my plants are growing and i want to re-scape my tank (i have a 125l)
how should i go about changing my substrate and more importantly what to?
I've heard that ADA Aquasoil is good but I have read some reviews which say it's not that good, if I did buy that how much would I need and do I need to cap it?
or are there any better substrates?
P.S. I know generally know the more you pay the better it tends to be (but not always this is true)
but I can't really afford to spend too much on money on it
Any help would be appreciated thanks in advance!
