The slime/debris tends to build up more where the water isn't circulating well or as much, like under your floating island. If you've got a small tank with a lower water level and a poor filter, 5-6 days is not unreasonable for having to do a cleaning/water change.
A larger tank would increase your options for getting a decent filter.
