Hi all, While my tank hasn't even come together, I figured I'd start a journal for planning purposes. Here is what I am envisioning, your comments and criticism would be much appreciated: Tank: 20 gallon long (30.3" x 12.5" x 12.8") Lighting: The tank will be sitting against a west-facing window, it will get 4-6 hours of direct sunlight during the year. I know direct sunlight is a very controversial topic, but I am hoping to avoid having to purchase a lighting system. Filtration: No mechanical or chemical filtration. I will be using an older Eheim 350 canister filter but it won't have any filter media and I will be using it for water movement only. Water Changes: I plan on doing 10% weekly water changes. Dosing: I don't plan on doing any dosing. Heating: In-line heater for use with Eheim canister filter. Substrate: 1" live sand bed and approximately 20 lbs live rock Livestock: 1 BTA, 1 pulsing Xenia, 2 captive-bred false percula clownfish, 1 midas blenny, 1 pacific cleaner shrimp. Please let me know your thoughts. Thank you!
