My wife asked me to set up a tank at the school she works at. Based on the equipment they already had and the fact maintenance needs to be super simple ive gone for a hillstream type set up with loaches. Not strictly planted, but i may add some emergent stuff. My input will be limited once its running, so with this they should be able to water change easily straight from the tap. The big rock has a sort of waterfall thing using a pump and spray bar and there are 2 circulation pumps plus an internal filter. Good to do something a bit different and hopefully there'll be enough to interest her pupils. This is about where we got to today.
