right now I am running a hex tank which for me has been fine to my learning and setting up so was wondering if anyone has a 40-150 gallon tank that they are willing to give away to me and here is the deal, If I get a free tank bow front or rectangle I will donate the 40 gallon tall hex to my sons school and teach someone there to do the day to day maintenance and will also go into the school once a week to balance and ensure its running to top notch, also I do have trades non reef related willing to trade for a tank. the hex has served is purpose for me and not ready to and need a tank I can be a little more open with so this hex if I come across a donation of a new tank for me will go to my kids elementary school and if they don't want it will find and local school who does and will continue to help the school keep this up for the kids and there science.
