Close loop ideas, 12mm glass tank owners.

[Reefocd]

I am planning a new shallow reef tank (3 side starphire, 66" x 24" x 22"h of 12mm glass non-tempered bottom top and bottom eurobraced, may or may not add front to back center bracing.

What I am asking;

Walk through your decision process to PROCEED with close loop and have glass drilled.

How many holes drilled? Placement? Pic would be welcome too.

I had closed loop in bottom of 150g acrylic tank with no issues. I did notice there is always pump vibration that occurs.

And.... Of course, if you had glass failure, please discuss.

Well what a coincidence i'm also having a system with closed loop starfire glass tanks but its a 3 tank system, on a 3 level stand. you should look at my thread i have plans and pictures lol we're in the same soup sort of speak. I had such issues that my LFS offered me the services of a pro aquatank engenier to the rescue lol.

I did a closed loop on my tank, drilled the holes too. When drilling a tank, make sure you are drilling into a piece of wood, and have a hole cut out that is acting as a jig. The jig will help stop hole saw from bouncing around. Use plenty of water, I used gliciren, plenty of it.

The inlet is at the top to avoid any sand that may get stirred up:

This shows the inlet coming in and along the base of the aquarium. The PVC was later covered by sand.

The plumbing is 1" in most places, plumbed down to 3/4" at the narrowest. There are a total of six points that shoot water at the rock.

Cutting the holes, nerves of steel!
