adding sump to 25 gallon

[sea student]

I have a 25 gallon tank at work that is not drilled. I would love to add a sump, but can't figure out a good way. I don't really trust the hang on tank siphons from what I've read on here. Is there a way to convert this tank, or would I need to get a new one? If so, what would you recommend? The stand/canopy works for tanks with the footprint of a 20 high. Thanks!

y dont u trust the siphon overflow boxes. i bought mine from my LFS for like $60 and it has worked great for 7 months now. i have never had it not work. it flows into my 10g sump

I've just heard about flooding issues if it stops siphoning. What kind did you get?
