As many of you here know I was in the process of setting up a 40b I got last Sunday at the $ per gallon sale for an endlers /pygmy cory/mystery snail tank for the grandkids. So while setting up the new Fluval 306 canister my son says Dad your tank has a leak. Low and behold my 75gallon tank (bought used from a guy who bought it used) has a tiny leak on a corner seam. So we proceeded to transfer all fish to the 40b and break down the 75 for resealing. Thank God I believe in planting heavily and stocking lightly. Had already seeded the canister with a large amount of media from my Fluval 110 hob. Went ahead and started this build thread so you can all follow along if I need help and can see the transformation of the tank to a large nano tank latter. Wish me luck!
