I know you can use florite, eco-complete or a lateralite base but what are people using with good success? To fill my 55 with florite will cost $80-100!!!!! Can you have a sucessful planted tank with 50/50 florite gravel (fine gravel) mix? I saw someone with pool sand???? that had a nice looking tank. I am setting up my 55 gal (i have a daily log in general forum) and need to get going on this. i am looking for opinions....I have tried plants with plain gravel with no sucess.
