DirtyCop Posted August 20, 2017 Report Share Posted August 20, 2017 I have a hanging filter that came with the aquarium kit and I want to add a sponge filter. Is it ok to add a sponge filter while shrimp are in the tank? Do I have to worry about parameters changing? I have cherry shrimp, some moss, and small snails. I bought BACTO-SURGE HIGH DENSITY FOAM FILTER and Tetra 77847 Whisper Air Pump, up to 20-Gallon Thanks! Quote Link to comment Share on other sites More sharing options...
Shrimple minded Posted August 20, 2017 Report Share Posted August 20, 2017 I think you are safe adding a sponge filter to a tank that already has a HOB. Quote Link to comment Share on other sites More sharing options...

DirtyCop Posted August 23, 2017 Author Report Share Posted August 23, 2017 Thanks. Problems keep coming up for me though...I've now removed my first filter that hanged in the aquarium-Whisper-that came with walmart tank setup-I guess they liked it in there. Long story short-I saved one, think I killed one or two that somehow got into very small spaces in that filter. I bought sponge to cover the intake but there were still screw holes that I couldn't cover which the shrimp were crawling into. Is the sponge filter with no medium added by me enough? It is powerful enough for twice the aquarium size. Just trying to save the shrimp I got, all parameters are very close to optimal. Quote Link to comment Share on other sites More sharing options...
chappy6107 Posted August 23, 2017 Report Share Posted August 23, 2017 You need to keep the media from the 1st filter in the tank (assuming it was cycled) so that you dont start a mini cycle. Quote Link to comment Share on other sites More sharing options...

Put the bag right into the tank? Quote Link to comment Share on other sites More sharing options...

DirtyCop Posted August 23, 2017 Author Report Share Posted August 23, 2017 I just dropped it back in there, will take it out tomorrow. Shrimp are super active and can see more than ever, so doesn't seem too bad. Quote Link to comment Share on other sites More sharing options...
DirtyCop Posted August 23, 2017 Author Report Share Posted August 23, 2017 Sorry to be redundant, but the shrimp are clinging to the Whisper filter cartridge. Is it possible to stick it in the corner of the tank behind the sponge filter, while covering it up at bit with Java Moss to make it a bit more aesthetic? To me it seems like more filtration which is rarely a bad thing. Quote Link to comment Share on other sites More sharing options...
chappy6107 Posted August 23, 2017 Report Share Posted August 23, 2017 if that media was out of the tank for very long at all, then the "good" bacteria are probably dead. How long was the tank cycled for before you added shrimp? Quote Link to comment Share on other sites More sharing options...
DirtyCop Posted August 23, 2017 Author Report Share Posted August 23, 2017 It was out for less than an hour. It was cycled for about 5 weeks before shrimp added. Quote Link to comment Share on other sites More sharing options...
