nice set up there.....i kept discus till i decided to go marine......the only advice i can give you is keep the temp at 84 - 86 and the ph 6.0-6.5 and you won't have any problems....the problem with this is your plants won't like the heat.....i also done 50% water changes every week.....with these setting my discus spawned almost weekly and grew to 10"....their awesome fish and if the waters right you won't have any problems.
