Hey guys I'm wanting to run a sump on my tank and I can't drill it as it's already set up so hob overflow is my best bet only problem is how can I make it I read up on PVC standpipes or an acrylic box like the shop bought ones can some one show me designs for it or something it's going on a 55 gal I'd like to run duel overflows to stop the chance of blockages
