I have 4 of these PG02708.jpg
2 of these lees-triple-flow-corner-aquarium-filter.jpg
and 1 of these, and this is the one I don't understand where the chemical filtration is, if at all 20120924120342500.jpg
 
Yep standard sponge filter. As I said in the pm a lot of people do not like to use carbon. But its possible to make litle carbon cartridges to drop in the up tube.

I personaly love sponge filters they have great bio filtration and polish the living heck out of your water made the tanks I added them to crystal clear. and if your water changes are regular carbon is kind of a back up plan anyway.

ooooooooohh, ok, now I see what you mean....figure out a way to rig a carbon pocket in the cylinder on top. GOTCHA!!! I was confused w/ that one.

I am correct though, the "Sponge" filter in the pic has no chemical filtration then? The tank that has that one has fry, and it also has one of the Triple-flows in it w/ carbon, filter wool and polishing pad, so basically the Sponge just gives me "extra water polish"?
 
Here's the little tyke for now - I only turned the light on for 30 seconds to get pix.....it will stay off until he settles in and starts eating most likely.

that's him in a 10g....barely the size of a piece of gravel LOL
 
Anyone raise an Oscar at 70F? I know most people would say 72F for tropical, but does the 2F really make a huge difference?

Obviously CAs would be ok and I have/had several species that do perfectly fine well into the mid-to-low 60's, but I'm curious about how an Oscar would do.

The only SA I think I've tried it with are "Geophagus" brasiliensis which did great all Spring and fed like normal, but could this have to do with their Ocean-going ability?
For what it's worth, a local aqaurium store owned and run by the same guy for over 30yrs now has always kept his water temps at 19deg or 66F in the winter months without any troubles. He has both fresh & salt water fish of all varietys. He runs the lower temps in an effort to keep his electricity bill in check & advised me to do the same but I dont bother so much especially if I'm try to get my fish to grow as that is the only downside of lower temps.

19C??
 
Temperature has more of an effect than just slowing down fish. It can be an important factor in digestion and other functions. Sure the fish won't die suddenly in colder water but that doesn't mean it's a good idea. Your tank should mirror the environment the fish evolved to thrive in...not the temperature they can technically survive in. If someone locked me in a cave at 50 degrees year round with no clothing or way to compensate for the temp I wouldn't necessarily die but I would be be happy about it.
 
Sponge alone realy should be fine frank. Unless your on well water that REALY needs the carbon. My axlotls are in a sponge only tank since it limits flow and they like still water. They have been in there a little over a year now .

As for the temps Like I said before a temporary drop from a failed heater is no biggies with most fish unless it gets realy cold (lost my wifes blood parrots that way) but I wouldnt go long term with it.
