Eddy there's nothing smaller than a 606, I thought I saw a 404 online too? I'm looking at the tank now and it makes my AQ skimmer top move and its on the opposite side where the fuge lets water out. The water surface circulation is there, the antenna on the hermits and snails move and their on the opposite bottom corner of the tank diagonal from where the waters coming from? Just trying to give as much info so I don't have to go out and spend more money... Plus, I don't want to get a powerhead and blow the entire tank away... So is there any other options? Again its only a 4 gallon so maybe I need to play it safe? I heard there was a spray bar that distrubutes flow evenly? My tank as so much already for what little room I have but what ever makes its thrive is worth it.
Last but not least the Chemi-pure has been in the tank for 1 and a half days now. And the waters still coudy, does it take this long? Here is the set up. I have the fuge and a baffle before entering the fuge. Right before the baffle is the chemipure surrounding the tube that comes from the tank into the fuge. So the water has to filter through the chemi-pure before entering the fuge. That should be okay right? :sad:
