overflows

[christyf5]

Well its high time for a new tank (its a 90, same size as I have now but eurobraced and unscratched ). I've got one ordered up but it isn't coming with an overflow box. Quite frankly I thought it was rather expensive and I could build one cheaper (why I do these things to myself I'll never know ).

So anyways, I was just wondering what the consensus was these days on overflow teeth. And mostly how do you figure out what your overflow will be rated for? Is that based on the number of teeth and how close together they are?? My last overflow box was built by Brad, I measured it up and he made it. It was hardly any work at all!

Some tanks I've seen don't even have teeth, the water just goes over the acrylic and works like a charm. I'm sort of leaning that way as my overflow teeth seem to grow a goodly portion of algae (as does everything else in my tank ) and I can't seem to get it all out of there. But at the same time, I have small gobies that, quite frankly, are a PITA to get out of the overflow once they get in there. I guess they figure its a fun ride or something. So I was thinking if I did go with teeth they'd be closer than the ones I have now (about 1/4" apart).

So ya, opinions/suggestions?
