well the 75 is too much right now with school, a new baby, and only one income. So I am gonna downsize back to original 30 I started with (the circle of life) and I wanna to things different and better this time.

1. I have an external overflow but would like to get the 30 gallon (glass) drilled for an overflow elbow (90 degree) turned upright in the corner. Do I need only 1 or do I have to have 2 oveflows??? I will be runnin a mag 7 for return flow. Also...where in SA can I get holes drilled in an aquarium.

2. I dont wanna lose all my macros/mangroves so I was gonna do a 10 gallon sump underneath. Will acrylic bond with glass and if so what do i need to use to get them to bond.

thanks for all the input. :cry:
