thank you, the rock wall took quite a while to make and it achieved my ultimate purpose which was to separate the eco complete from the front of the tank. i have a couple of pigeon-based red melons which would pepper if i had all eco complete as substrate. as far as lighting goes i have 2 JBJ fixtures with 4x 21" 6500K 65w bulbs. they are all indeed low light because i did not want to start with any difficult plants. obviously even the less difficult plants turned out not doing well for me. i guess i have a brown thumb, lol. people were telling me that i have too much light and i would need the co2. i'm in the research stage of that plan. i would love to have some nice planted tanks like the ones i see around here.
