    Cutting Acrylic

    What can i use to cut acrylic? I have an overflow box for the skimmer intake and the outflow falls into a second part of the box (with a hole on the bottom covered by a sponge so that the air wont get in the tank) Well the outflow section tends to overflow into the tank and i have tons of microbubles. I was to cut the notches on the overflow side deeper, so that i can raise the whole box up higher this way the right side wont overflow and the left side will still take in water. currently if my water lever drops by a half inch it does not overflow into the box anymore. so what can i use to cute the notches deeper? a regular knife? or do i need a special tool? and how do i do it?
    thanks.

    Harley is your man for this....he lives in acrylic....I think he prbably has an acylic house, car, pet, and maybe...oh never mind...hahahaha

    I use a table saw with a fine blade. If it's thin I use a utility knife. Ask Harley though...he has the experience in this stuff.

    The only thing two reef keepers will agree on, is what the third reef keeper is doing wrong!

    Dremel tool

    Are you going to do this with the tank running? If so BE VERY CAREFULL using power tools around SALT water .... If I had to do it I would use a high speed dremel or dremel type tool with a bit that is correct for plastics. Protect the tank with something or it may get a bunch of dust and or shaving in it. Make SMALL adjustments at a time and re- test flow rate each time. Good luck.

    Using a drill is risky. When the bit is just about through the other side they tend to grab and the plastic may CRACK. High speed tools reduce this risk. It's likey best to wait until Harley responds ... from what i see he's the man.

    also, is there a need for the notches in the overflow? why not just have the whole thing a little lower? i feel like it restricts water flow.

    ok, considering that i already had taken out the box, i decided to just figure it out myself (seems like harley is out partying tonight). I used the side of a drill bit to pretty much "sand-down" the holes so that they are deeper.

    Albert,

    Go get yourself a Dremel kit, this will be one of the most versatile tools you'll ever own ...
