Getting ready to build my first sump and I wanted some quick advice.
I'm building it with a 29 g glass and just siliconing in glass baffles. The dimensions are: 18" tall, 30" long, and 12" deep.
I have an overflow box that uses two "U" shaped siphon tubes draining into a center chamber that then overflows into two separate drain tubes.
I would like to have my return chamber for the sump in the center of the sump and drain one of the drain tubes to each side. So basically the sump fill fill at the outer two chambers and flow to the center where it gets pumped back to the tank.
On one side of the sump I'll house my skimmer. And on the other side I'd like to have the drain feed into a tall camber of LR
rubble before it over flows into a refugium and eventually over another baffle into the return chamber.
I hope I painted a decent picture of my plans without confusing everyone. So here's a few questions:
1. Do I have to worry about balancing my flow and drain rates or will my overflow box automatically siphon water at the same rate that my pump returns it?
2. What concerns do I have with power outages and flooding?
3. How can I maximize flow over and exposure to my LR
Rubble? Can I run my drain tube all the way to the bottom of the chamber forcing it to rise through the chamber and spill over the baffle into the next? or does the drain tube have to drain into the top of any chamber? My concern here is that the if the water drains into the top of the chamber-it will then spill right over without mixing with the rest of the water in the chamber or recieving the benefits of the LR
Thank you all for your time...I hope I haven't been too confusing
