I have cabomba, anibias nana, 2 corkscrews (not sure what kind), java moss, java fern, amazon swords. I have 2 watts per gallon, soil covered with pea gravel, liquid fertilizer, filter, temp is 75. the plants are super healthy as are the fish. BUT nothings grown, the java moss hasnt moved a bit in 3 weeks, everything else has been the same for a month. i just want a VERY grow out tank with a carpet of java moss. how do i get it to grow faster?
