    As frags are taking over my main tank I want to move those out of my tank by setting up a frag tank next to it, and I saw this on amazon

    is it good idea to use the plastic bin or just build a small shallow glass tank ?

    you are going to plumb it into your main tank as well right?

    You can just get a good ol 20g long and drill the overflow lower for "shallow" tank.

    Don't use plastic tub, you want to be able to observe the condition of the coral easily. Tidal Gardens is moving away from 300g Rubbermaid to all glass tank for this.

    ok will stick to glass then, the frag tank will have it's own 20g sump

    Why not connect it to your DT for better stability? Maintaining parameter for 2 tanks is no fun.

    good point. guess I will need to re-work the fish tank area and see if that's even possible

    My plan is to plumb a 7gallon frag to my system

    My frag tank and QT are one and the same! Basically I'm sneaking an extra tank by my wife by using it as QT while the main tank solves it's nitrate issues.

    I've used similar plastic containers for frags.

    Just threw on a HOB filter with a heater and media in the compartment and propped a light across the top of the tub.

    Didn't need much light for such a shallow setup, and top down view of the corals was ok for me.

    You can just do water changes from the frag tank back to your main system. Frag tank is fairly clean, and main system can handle water processing.

    A setup like that was good even for me to have a pair of frogfishes spawn several times.

    I've used a 7 gallon minibow for a combination frag and frogfish tank. Just changed water between the MB and main system.

    I made my own out of acrylic 16x16x7

    Could cut down an old acrylic tank.

    I had never really thought of doing a frag tank since I didn't want to maintain 2 tanks but I've got quite a bit of room in my fuge. I might just add a light and put a frag rack in there.

    That is what I do as well. Coral QT and frag tank.

    Frag tanks are nice if you really want to grow out coral for distribution either planned or unplanned down the road. While those plastic bins certainly might work, I would advise against any long term usage of them as they're really not designed to hold water to the brim full time. They will bow out and that might cause them to crack in the corners.

    My advice is wait until Petco has one of it's $1/gallon sales, you can get 10g glass tanks, 20g breeders (shorter and longer), even tanks up to 55g (I think). Looks nicer, you know it's designed to hold water, and you usually can drill the sides of them (bottom not so much usually)

    40 breeder makes a nice frag tank.

    I drilled the back for 2 drains and siliconed in a strip of glass at an angle the full length across the back for an overflow.

    Used a plex box on the outside with a durso.

    hell a 40 breeder makes a nice display tank! Got the right proportions that makes it feel big without being too short. Man part of me wishes I was my younger unmarried self who had multiple tanks around the house :D

    Norm, did you bevel the edge of the glass you used for an overflow? Or did you leave it squared off?

    I just took off the sharp edges with some wet carbide paper on a wood block.

    I think you had posted images of the tank years ago on the old, older BAR site?
    Cool coast to coast DIY, right?
