I have the tunze 6055's and I like the pulse setting but you don't need it. Look into the 6045's, they are flow adjustable up to 1190gph (i believe), and are under $100 each. I love the vortechs but there are other options out there that don't hurt the wallet as much

this coming from a guy that spent $100 on a frag:razz:....just buggin ya bud:biggrin:

It was like $190 for a nubbin lol

in the words of Jdigital "you paid that much for that!"

+1 on the 6055's they are an awesome powerhead for a smaller tank, I have one in my 27 Gal and they are great! They are actually around the $225 mark but still a good value. You can't beat the quality of Tunze products. I do have two of the MP40w ES PH's in my larger tank and I wouldn't give them up for anything.
