Closed loop advice

With the exception of some hair algae the tank is finally starting to thrive again after moving a few months ago.

I did just this on my 180G thread...the center brace letting go helped the rebuild decision, but after 6+ years of a 180G full of powerheads, I decided to take the OM/Dart leap, and after @ 4 months I have no regrets. Re used 90% of the old sand and rock, and about 75% of the old water.

I ran 2 SQWD's on my returns from my sump on my 180G prior to the upgrade, and I have to say for the dollar amount they ran fine. After switching to the OM and Dart though, I have since ordered a custom Squirt to replace the SQWD running on my 75G. I will still use the SCWD's on my frag system, but I really like the design and extra flow you get through the OM.

I realize the OM is higher qualilty and can handle higher flow, which probably works very well on your 180. My 65 would only demand SQWD I think.
