The blood parrots really pump out the waste,the tank is a 20 gall.We do not have the money for a new tank at this time as I spent a fortune on this setup in current use.This 20 gallon has a penguin 200/50gall.and a whisper power30/60gall.two air bars that span the back of the tank,Lots of aeration,I am using aquarium salt as well as stresszyme .The tank is clear ,the parrots are eating and active,Yet The water test kit ,as well as the 5 in one strips indicate VERY high levels of trate and trite.I have noticed the levels dropping could it be cycling and how long does this process take. I am also thinking perhaps less is more with cichlids.Perhaps removing some of the ornamental goo-gahs would help facilitate gravel vacuum.Please,whatever pearls you can throw in this swines' direction*twirlysmi -D
