So one of the problems that many people have had with the slide out filter in the back is that it doesn't sit totally square so some water can trickle back and avoid the filter. That won't do! I really like the pull-out concept so I don't want to actually seal the back permanently. Solution was easily identified using that nifty search feature on Nano-Reef.com!
I purchased some black airline tubing, cut to size and slit lengthwise. This was then slid of the tops of the back pieces and will form a secure fit.
(bonus points if you saw the Hokie Bird in my t-shirt. Go HOKIES!)
Next problem - the pump. LOL!
The pump that comes with the tank is 75 gph, which isn't even 10% turnover. It's also the right size for a beta tank!
(Next to a pair of scissors for size comparison)
This is how, if Cadlights had their way, the filtration would look:
That will never do.
The removable back proved easy to take to the LFS and engineer a solution. I test fit several power heads and found the Maxi-Jet 900 was a great fit. I cut down the sponge in the back to support it properly and attached a hydro-flo return to the other side. I intentionally went with a 230gph pump- by my math there is probably a 30% decrease in output when you use the hydro-flo dealio. That makes this pump output more like 160gph which is a much more acceptable! I also like the first chamber as a refugium so I decided to make the second chamber the filter chamber and cut the included sponge in half. This will provide space for the Purigen and carbon after the sponge before the water passes through the final sponge.
Comments and philosophical debate welcome.
