Needing something more

[Rushb3]

Ok so here is my first hurdle coming back into this hobby, I impulse bought this all in one Frag tank and honestly I think the filtration sucks! It needs something more I want to do a sump but it’s not pre drilled and i am terrified of the “what if the suction is broken” on the over hang overflow. Any ideas would be greatly appreciated !!

First off welcome back. I have AIO biocube that I put a Fluval FX-4 on. I run everything thru the back of the tank thru the lid. The hoses pull and fill the factory “filtration “ system. That way I also have a spot for a refugium as a bonus

If it's not tempered glass I would drill and go with a ghost style overflow like synergy or eshopps. At least that is what I did on my shallow reef.
