my 15G is DOWN I SAY DOWN! there was a ich out brake in my 15G and i dident put the stuff in on time, and i lost most of the fish, im bummed out. i took the fish that surrvived and put them in my 20G(that was 1 otto and 2 platys). the 15 i took out all the water, and cleaned everything, i am puting the tank back together over this week bacause im on spring brake(one week). so im realy bummed out, bummed out so much. *SUNSMILE**SUNSMILE* but on the bright side, i have a new filter for the 20G it is the EHEIM Ecco 2232, i love it! it is so quiet! quieter than the aqua ball. so now the 15 has the aqua ball once i clean it out and the 20G had the 2232 from EHEIM. c ya!
