Bowfront diy filter help. Mfk help me please

[ale248]

Ok so I have a 46 bowfront and I have a mirinland 75g filter on it.
I wanted to do a diy filter in it maybe a sump or something to get the water really clear.
Question is since I can't drill it what can I do?

Give me some options I have to filter my water more please thanks guys

if you want a sump without drilling, use an overflow box or DIY pcv overflow. there's a million overflow builds here on mfk. check em out.

i just picked up a bowfront, and i know the bottom is tempered, but what about the back?

i had planned on doing another gl*******guys.com system with a 40 gallon breeder that i have for a sump.
