Its been about 6, or 7 years since I tore down my 5 saltwater tanks, and I used to think I knew it all. Funny how time changes everything.!
My problem is water circulation... Too much, not enough!!!! My 55 gal
swim tank with two Millenium 550 pwr. heads (for circulation ) My penguin 330 bio-wheel pwr. filter does Ok, but it just doesn't seem to be enough current throughout the whole tank, I recently tried putting my Rio 4HF hyper flow pwr. head in with only one of my other pwr heads, and it seems too much! anyone out there got something for this Circulation confusion!
