hey catfishmike
thanks for the idea about the filter sponge, i've got some stuff to chop and throw in.
proquatics fiters are very neat in my opinion. What first attracted me to them is the space in the filter itself to add in what
i mentioned before for bacteria growth. The filter itself can be a bit of a pain, setting filter media in it can be a little tricky simply by the nature of how the filter works. Water goes in through the uptake tube, then is routed to the bottom of the filter and up through the tube shaped filter media. which also allows flow control (theres also flow control on the uptake tube strainer, you can set the size of the strainer slots, it can be a pain however) Once the water comes up through the system at the bottom, it hits the filter media, which you can also add small bags of carbon which must be soaked completely before you add them in the filter, the floss bad the carbon comes in is rather thick. Then the water flows through the floss container and back out into the tank. Now, the filter media can be expensive, 5-7 usd for one replacement. But they last a while and you can also simply buy new wrap around floss if you choose, but i havent used it yet. This filter is cool for one reason in particular, its setup in a way in which you can design your own DIY filter media built in layers or still use the same wrap around function. I plan on expiramenting allot with this filter once the tank is cycled. It could pay off... I know i can already make my own carbon bags if needed. but overall, i'd rate this little bad boy an 8 out of 10. Considering the design, price for initial purchase, and possibility for diy media, this filter has potential, they simply need to make a few things less flimsy. Tomorrow ill chop up some sponge and toss it in the filterbox. Oh, and the floss filter media for this HOB is very effective, doesnt look like most floss seen in common whisper hob's.
