Hi all, I'm trying to decide if it's worth the money and time to mix my own saltwater or just buy from a LFS. My tank is 20 gallons and I figure I will need the following: RO/DI device - Does anyone have any suggestions on brand and model? Water storage - What's the best way to store RO water and mixed saltwater, home depot buckets? Hydrometer Mixing pump Salt - Almost missed this one. Any particular brand suggested? My tank will most likely not house any hard corals. Fish will hopefully be captive bred. Thanks!
