I have a 55 Gal FWOLR that gets about a 15% water change once a month, it's thriving no bacterial blooms and everyone is healthy. I have a Fluval 407 Canister Filter as well as HOB Filter because I feed heavy. Two weeks ago I moved over my Evo 13.5 reef into the FWOLR as I just want one mixed reef tank. So far so good but my question is this, do I now need to do weekly water changes or am I fine as long as I'm testing and parameters stay the same? I don't have a ton of corals but I'll keep an eye on alk, cal etc
