so i have 2 emp 400's on my 55 gallon w/ a single oscar,my question is this is as follows.on the emp. they have 2 slots on each side of the filter,two empty cartridges that you can put your own carbon mix in and a 2 slots that you put the pre made carbon filters in.Many times i hear people that say carbon isnt really effective and to take it out.SOOOO i looked around to see what i could do different.i found 2 different replacments.
1) one with a carbon/floss bag that makes the carbon not settle and a sponge on the other side for bio needs. http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=13371&prodid=24760&catid=888
2) one with a bio ball type wall and on the otherside a cabon impregnated waste trap(looks like a sponge)
http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=13375&prodid=23604&catid=888
would either of these be better than the "standerd"set up i have now,or is there something even better i can do to my emp's. thanks for you help
