I just got two SIEO M1100s for my 110g tank. The flow at high output is VERY nice. At 15 second intervals (even if it goes from 30-100% on BOTH units), don't you still get a desireable effect? I don't understand why that announcement seemed to cause so much chatter...
I'll admit that price was a factor when buying these over a set of Tunze, but reading this thread a while back made me go ahead and buy the SEIOs - and now I am anxious to get my hands on the product. My only concern is that I saw it mentioned that these guys "felt warm" - how warm? Would having the controller set at 15 sec intervals make the pumps warmer than the longer setting? Is this something that'll heat my tank to the point I need a chiller?
After seeing onetrickpony's mod, and the posts after his, I think I'll stick my SIEOs on my MagFloats (I think mine is the 3x3" one). I'll need another (as I think they will easily hold the weight of the SEIOs). I think a DIY multi-functioning algae scraper/powerhead would be awesome! :smokin:
