Slowly pecking away when I'm not doing honey-dos. For a bit of reference, the drink in the foreground is a Route44. (44 oz). It is about 71" x 21" tall. There are a few more caves now than shown in this picture. I am about ready to Drylok / paint. I've ended up making several compromises that have sucked. The best laid plans of mice... I suppose. The heaters will be on the ends in front of the background. I've notched the ends. (Not shown in the photo.). Once I actually bought my FX6, the water intake is huge and can't be totally recessed into the background. The hose back into the tank wasn't exactly like I imagined from reading about the filter. I didn't want to have to cut it into pieces for installation as shown in the videos. I didn't think about the tank's cross supports on top. So, now I have to cut it into 3 or 4 pieces and then paint.
