is this substrate enough?
hello im planning to have a low maintenance planted tank which will consist of only, anubias barteri var. nana, anubias coffeefolia, and crypts. i have no special substrate such as ADA soils for example, so i am using plain gravel as substrate. Thats right plain gravel only because my tank has been established for nearly 2 years. The gravel ranges from 2mm-4mm in size and is about 2inches high.
size:4ft x 1.5ft x 1ft
lighting: 2x 40w 6500k
Co2 : DIY
inhabitants - 17congo tetra, 6 SAE
will this subtrate be enough for the plants that i plan to keep?
