Tank has been up and running for three months. Right now Im running a Reefoctopus SRO2000 for a skimmer. Will want to upgrade to something a little larger down the line. Its set up with an apex for control but I will need to a some more outlets soon because they are all filled and everything is not running off it right now. For my ATO I have a tunze osmolator and a 37 tall cube under the tank. This is perfect because I only have to fill it about every three weeks. I just set up my BRS dosing this week. Now that the tank is a few months old I am starting to see some growth on the SPS though its still on the slow side for most things.
