Drilled or External Overflow?

[bigbadbrent]

Looking for some thoughts on having a pre-drilled tank is a better option then having the external overflow. If i have it pre-drilled, im committed to having a sump at startup, however if i go with an external i can add a sump later?

Any opinions either way?

Thanks

definitely drilled it is a safer way to go less chance of flooding

I can't think of a good reason to not have a sump, so I'd go drilled.

Go with a drilled tank...I have a 55 gal. Not drilled...more equipment than rock...go with the sump less hastle in the long run...my new 120 gal. Is drilled with 90 gal. Sump

External overflows are a hassle. Drilled is the only way to go if you have the option.

Go drilled even if you are not planning on using it right away, just plug the overflow. External will end up costing more in the long run. Go for a sump off the start, you'll have WAY more options and stuff will be cheaper. Even if it's a rubbermaid tub it'll still work, i've done this for emergancy sump's before.

Been using the same external overflow for 6 years no.
has never lost siphon and has never caused a flood.

Anyone who thinks that drilled tanks carry any real benefits either have never used a good quality external overflow or they simply did not know how to set it up properly.

It takes up significantly less real estate, is WAY easier to control and clean and you have so many options for placement plus you can always move it when neccessary.
