Help With Filtering - So Many Choices!

[DanMan092]

Alright, basically, I need help deciding on my overflow. Here are the choices...

BTW, we have a generator in case of power failures

Feel free to add some

1) A CPR Overflow
Advantages - Less complicated than other
Disadvantages - Many people report that it gets clogged and loses suction. Therefore there pumps keep chuggin and they flood the room, therefore would have to get a floatswitch. If gone for a while, it could be off for quite a while

Notes: Many people say that as long as you keep it clean, it will not fail.

2) Drilling the tank
Advantages - Can put the intake, outtake in the back
Disadvantages - Have to get the tank cut, and far more complex piping. And if stariners are put on, will stick out.

Notes: This is the safest way

If both of these suck, tell some and maybe post some sites with piping instructions etc. Or maybe your own successful system.

Get it drilled, you'll be very happy that you did, saves on a lot of worrying. I drill all my own tanks, not hard at all, wish you lived close by, I'd drill it for you.

I would be vary wary of using a float switch to back up an overflow.

Always plan for everything going wrong (cos if you don't, it will!). Float switched are by no means fault proof. Go with what Superman says. Drilling is so much better, and usually cheaper than massively overpriced overflows.

I don't understand why the pipework will be so much more complex with a hole. If the hole is in the bottom then the pipe goes straight to the sump rather than negotiating the side of the tank/stand with an overflow. The returns will be idnetical...
