Thank you. I will check out the video when I get out of class.Yeah I think the DCQ's are still making their way into US/Canada, not super easy to find there yet (there are a few listings though on ebay and amazon), though they've been out about maybe 9 months here in SEA I'd reckon.
I'm currently running a DCQ-3500 in my 115 gallon Kamfa tank (just goes to a Sunsun pre-filter then UV sterilizer). Works a charm and quiet as anything, the air pump is way louder. I plan to get another one of the same model to put inside this tank's internal corner filter (currently has a normal Sobo pump). I also have DCT & DCP pumps on other tanks, no problems and equally happy with them.
Here's a little video review of the DCQ-3500 if anyone's curious to watch (when it was in my Kamfa's then 88 gallon tank):
Side note: I mention about a suspected issued with the pump not reaching it's max power rating (28 watts) -- a viewer made the correct point that max wattage will be influenced by how much head pressure you have on the unit.
It appears that the only difference between the DCP and the DCQ is the wavemaker capability. For a reef tank, I can see that being very useful and worth the extra money, but for a freshwater tank, I don’t think it’s really worth extra money. I would probably still get one though. Lol. If their prices were the same then it would be an easy choice. I do like the red color though. Maybe my son’s 29 gallon tank needs a sump now...
