Well this past spring I setup my first true planted aquarium.It is a 100 gallon.It has been a learning experience and I have enjoyed it.The plants are growing like weeds, as a matter of fact I have ran out of room for the fish.Well now since I have the plant bug I want to convert my 72 Gallon Bow tank to a planted tank.I have Discus in the tank at this time and I plan on keeping them their.I now have a 260w power compact light on it.My filter and heater will all do fine.In my 100 gallon I went with Eco complete. I must say it was a nice chose and has served me well.But I have been out of work for 11 months and just can't afford to use it in my 72 Gallon Bow too.So what I want to know is if Silica Sand will do OK for plant or is it better that I just stick with the fine gravel I got in it now?I plan on keeping Amazon sword plants.What do you guys think?I have seen many Discus tanks will silica sand and I like the look of it. It is the Ideal substrate for discus as they are scavengers and like to let their food sink before searching for it then eating it. :headbang2:
