2 Drains 1 Input - Plumbing Help

Simply__J · Nov 28, 2016

Currently in the middle of plumbing a 45 gal cube with a small overflow with two 1" drains. However my Proclear Aquatics Freedom 4-in-1 100 refugium only has one 1" input.

Should or can I plumb them together so they both drain int to the 1 input? As pictured (Will that have any restrictions on flow or tank turnover?) Or should I keep them separate?

Thanks in advance for your help and suggestions.

If it was my system I would make the 2nd drain an "emergency" one with a slightly higher standpipe and have it dump into any open area (sump).

That may not work as I originally wanted to use the Herbie method but quickly realized that because the drains were horizontal I wouldn't be able to do so. Also the overflow box is really small as pictured.
