Hello, got an invite to this site. Won't mention names just in case :D\n\nHave a unique project, attempting a Reef tank in a Aussie wall Tank, approx 9 gals.\nDem. are 44Lx15Hx3.25 W. I have decided to go with a canister set-up with The Ehiem, not sure of model yet 2211 or the New 2236, advice? My concern here has been flow rate. With this narrow tank and only, (with sand and LR about 7 gal), of water anything over 60L/h is going to be to rapid and harsh for anything!\n\nAlso, this tank is maintaining 74 degrees without heater or Lights! Plan on raising lights today. Going to hang the Coralife so it is adjustable with weather.\n\nI plan to also put in an in-line UV system [url]http://www.petmountain.com/show_product/11442-572103[/url] , and an in line heater for insurance and space Hydor ETH External Thermal Heater - In Line Heater. I'm also going to purchase an RO/DI system. I'm looking at this one; BRS 4 Stage Value PLUS RO/DI System - 75GPD. However think there are similar systems for less from a vendor other then BRS. Any suggestions?\n\nAll suggestions will be appreciated keep in mind here where talking NANO. \n\nAlso, being an injured man I have lots of time, not to much cash, but want to do this right. I know it can be done.
