Hi, basically I am stuck on substrates for my 25 gallon tank (with 50w of lighting) and I may go EI, although I am not sure atm. Does anyone have any pros/cons for tropica substrate or tetras? I really dont know which brand to trust (and my friend calls tetra 'retard substrate' for some reason lol)
thanks
thanks
