hello to all! i am doing a 90g setup to house about 6-8 discus, however i would like to automate the maintenance as much as possible. so i will use the fluval fx5, stocked with chemipure, and seachem matrix. i will also run an aqueon proflex 3 sump, in refugium mode, with hornwort, frehwater miracle mud, more matrix, and possibly a deep sand bed. given that level of filtration, (and a uv sterilizer) how often, and how much water should I change for these discus?
