Where to drill holes in my 180 for closed loop?

MarineGirl411 · 09/21/2009, 02:57 PM

Here are some pictures of the tank I will be getting. I will be drilling for a closed loop. I wanted to know where would be the best spots to drill for a closed loop in this tank to prevent dead spots? I will be using a dart and two 3/4in sea swirls in conjunction with drilling. Please advise on the best placement for holes and sea swirls. Thank you so much. =)

No where, Use 2 Vortechs or Koralias. Much more versatile and little electricity. My 2 cents.

OH, and no leaks!

Right now can't afford to do that. Plus I have all the tools, bulkheads, piping, and pump for a closed loop. I do not like the look of power heads. I have a closed loop on my 40 breeder right now. I love it.

Can't blame a guy for trying. Enjoy!
