I am planning on starting a shallow 30g sps and jus wanted to see what shallow sps tanks that the community has. I have a chance to make a custom sump and want to know what you guys have in your sump and what media reactors you have and recommend. I will only have about 24"x24" for a sump so would only really be able to add the essentials for a sps tank. Let me know what you guys think. Also bare bottom or sand?
