It looks like you are off to a good start to your tank and your build thread - thanks for all of the pictures! You may want to add a build thread banner (which doubles as a link to your thread) so people can find your thread more easily.
Here are the step-by-step instructions to add your build thread banner:
1. Copy your build thread URL
2. Click here to edit the link in your profile: https://www.reef2reef.com/account/account-details
3. Scroll down the page until you see "R2R Tank Thread Link" and paste your build thread link in box next to it and then select "save"
4. Your build thread banner will show up below your name in all of your posts!
Build is looking great. If you get a sec grab that sweet build thread like @Peace River mentioned. Lets everyone know you have a build we can check out.
Also, one piece of safety advice. I would strongly suggest securing all the barb to hose fitting a bit better. BRS and Marine Depot sell plastic hose clamps as well as some hardware places. Once you get them I would shut down the pumps for a few minutes. Heat up some water in a pot or coffee cup. Pull each hose off the barb one at a time and soak the hose for a second to get it soft, then it should press onto the barb further. Then secure with the clamp. The one you have on the very front ball valve left side really needs to be on more.
