If i did a 20 gallon long tank with about 3-4 Amazon swords and some type of grass on the bottom (maybe dwarf hair), about maybe 3-5 bundles, would i need a Co2 injector if i dont have over 2 wpg? i plan to get a light tube that is only 20-30 watts.
The thing is, i dont really understand how to make a DIY injector and i cant buy the canister one which is more expensive =(
also, would a gravel substate work? sorry, im not to experienced in the field of planted tanks
