If you are set on a second drain, I would go with one in the opposite corner, but be aware that the overflow is going to take up another 6"x6" of tank space. How big diameter is the drain you have?
They would be next to each other but if they are at different heights you won't block both so say your main drain is closer to the bottom if that gets clogged water rises then your emergency kicks in when it reaches that height in fact my emergency drain doesn't touch water unless a clog happens, again read up on a herbie style overflow completely quiet and safe.

Depends on where your return is located. If they are both in the overflow box then make it a drain. Do a herbie, so quiet, My equipement makes most of my noise. In my tank I had a drain in a overflow and the return in the other corner, I herbied it. And have my return coming up over the back. I do see 1 (emergency drain line) but if it had been the return you'd still see it. I like the peice of mind of having a back up, incase something happens.

Same here my skimmers bubbles are the loudest thing I hear, and I get no sump noise or gushing water I have mine made as a true herbie with durso emergency stockman standpipe as my main drain with gate valve and all my returns are housed in through my overflow .

Drilling isn't that hard either if you don't want to run the lines over you could also drill through the back for returns or another drain if your tank is drillable

Putting a snail screen on your drain keeps snails out as well. People have been running single drains for a long time and, I agree... if you clean your tank and pipes on occasion you should not have to worry about it.

Sure Denny, a second drain is nice... but not necessary. It comes down to personal choice I believe. Single drain tanks would not be out there if they did not work. Having an emergency drain is something easy to do if, say you build a 200 gallon custom and they factor the cut into it already.

I almost added a second... but after soliciting advice from several reefers and staff at a few LFS, I cam to the conclusion to leave my single drain and clean it and the screen.

Maybe its famous last words.......

I wonder... does anyone care enough to read signatures if you make them really small? I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.

A tank need not be custom made for a herbie style overflow and it doesn't need extra real state ......i mean CPR overflow boxes are " safe" but I wouldn't use one even though some say they never had a flood. And call me nuts but constantly moving and cleaning a snail guard( which would have to cover your complete overflow or us no more effective than a stanpipe filter cap) is not fun nor is the worry of it and it's def not pleasing on the eye, again I suggest reading up on herbie style overflows and then say one drain is as good . Fact of the matter is you can do alot of different styles but in the end having a emergency drain makes total sense and if it can be incorporated then it won't hurt in anyway , I also understand that some tanks don't have the option but I don't think that's the case here

herbie all the way baby lol the best fight against floods we have is being prepared for the worst case scenario. I

I guess we'll just have to agree to disagree on this one......

But I guess one could just put in four and fill up your tank with drains. It will look like crud, but will be extra safe. Thousands upon thousands of people have used single drains on smaller tanks for eons with zero issues. In fact I can't think of a single tank I've personally seen under 120 with dual drains.

I'm sorry wasn't trying to offend you he just simply said he had a concern and if there is something he could do as dril it, I said if he didn't want to drill he had this as another option. Yes lots of people run single drains and all my previous ones were as well but if he wants to do two he should be open to the idea as alot of people are now going that route cheers

I wasn't offended, thus the

And I agreed from the start, two drains are better than one, but I wouldn't do in in an 80. Maybe I just feel 80 is already cramped after having a 180, and I like as little as possible showing in the tank.

All this talk has got me really wanting to start up again.....man it's tough up here, no used tanks to be found. If the original poster comes across any other deals in YK, I'm interested.
