Unfortunately dkreef, one wc every 2 weeks will not likely cut it, and once a month will certainly not do. It will make it very difficult to maintain the needed water quality and conditions for discus, in addition to raising nitrates to an uncomfortable level for successful discus-keeping.
Using a python for more frequent wcs will not be troublesome or time-consuming, and you could get by with say 2, or 3 reasonably large, say 25-30%, wcs a week if your bio-load is not borderline high.
