A planted tank doesn't have to cost an arm and a leg. This is a 10 gallon aquarium, no CO2, light with 2 screw in CFL bulbs from Wal Mart
, and plants I bought here on the forum. I use Seachem Comprehensive and Seachem Excel for fertilizer 2 or 3 times per week. Besides the tank, I have a hang on back filter, substrate, and heater. Substrate is Safe-T-Sorb and is available online at Drillspot for $9.29 per 40# bag with free shipping included. 40# will do four or more tanks.
