i bought some of that moon sand it was 20 bucks 20 pounds,what a rip. i went down to home depot and got 50 pounds of playground sand for 4 bucks to put in my other tank and it just as nice. if you dont want that sand you can always get pool filtre sand which comes in 100 pound bags for about 10 bucks. but usually is only white. as for your plant questions. i have a 29 gal planted tank. i have some micro sword some java moss,java fern, money wort, amazon sword, bannana plant,a couple of red plants that i cnat remember their names and some bacoppa. it's all growing great especially the bannana plant. i've never used any co2 i just have some liquid fertilizer. the only problem i have is some hair algea but it seems to be getting better.
