In-tank circulation pumps

[aculross]

OK, second pump question - In my 120 (basically FO, but some softies) I also have a powerhead that comes on when the MH come on to increase water circulation inside the tank. I've seen reviews of these new small "flow" pumps (Tunze et al.) - What's the take on these? Are they worth the $$$ ? Can anyone recommend perhaps a slightly cheaper alternative to Tunze?

I have not had any experience with Tunze but Hydor Koralia makes a nice water circulating pump that is relatively inexpensive, reliable and is available in many models from 240 gph to 3,250 gph. They range from $27 to $150. Might be really nice for your requirements.

I use two Vortechs and a Tunze Stream on my 125. The wide flow patterns, energy savings, and controllability are the reasons to use them and they are worth their weight in gold IMO.
