  • UPDATED - Custom Internal Overflow Box And Drilling 125 Gallon Tank

    Hi All

    So after debating between internal and external overflows, i finally decided
    on an internal (after reading tons of forums and asking the guys at Bulk Reef).

    I could not find one pre-made that i liked so i decided to make my own:

    I already had a 25 x 40 peice of black acrylic, so i made the measurements
    for a floating center mount overflow: 20"x3"x5"

    I was going to do a regular 3 sided overflow glued at right angles but decided to
    try a more pro look by heating the acrylic and then molding it.

    Next i cut and glued the bottom to the overflow:

    The next step was to cut the drain holes for the water to flow from the tank.
    Again i was going to go with the regular square cut but decided to try the factory look
    with the holes recessed about 1/4" from the top.

    This was a bit tricky as i had to use a router which is not my favorite power tool, i made a
    few ooopsie's but got there in the end.

    Next is the tank drill


    Hey Guys

    OK, i drilled the tank last night

    The drill guide i have is a bit flimsy but it's good for starting the hole,
    i then switch to handheld which gives me more control and feel for
    depth.

    Using plumbers putty to create a well for coolant is a good idea but
    it also makes for a messy work area.
    Each hole took about 2 min (Glass 1/2" thick)
    The main thing when drilling glass is GO SLOW and of course a steady
    hand helps.

    Bulkheads installed on the 2 drains coming from the internal overflow.

    Question/Poll?

    What do you guys think, 1 return hole or 2?

    Done! Floating Center Internal Overflow with 2 Drains and 2 Returns at either end...

              The black acrylic was quite expensive $80 1/4" thick, but i want to make some more overflows for my other tanks.

              That's my next step, the diamond drill bits and bulkheads arrived a few days ago.

                      Good job on the acrylic work. I've used scrap pieces from Aeroshield Plastics that I've bought for like $5 for a 12"x48" piece on my overflow and other projects. As long as you don't need a piece wider than 12" you can get a great deal.

                        O man. Nicely done.
                        Very nice Job you did there.

                        I designed one similar to bulk reef supply for my 200 gallon but since I went all black pvc and black silicone I decided not too make it
                        Dims were 24" x 6" x 6".

                        Sooo.... When are you going to build an acrylic big arse tank?
                        I am soo down to help.

                            looking good! i would love to make acryllic terrariums but man its expensive. i wish i had stocked up when i used to get the stuff for free when i worked at TI.

                            nice job on the teeth, i was thinking that i would try a router and a finger joint jig for that. routers are the best tool eva but can mess things up in a hurry too lol.

                              Yip, working with the router was tricky, one slip an it's a mess, will use a jig for sure on my next box...
