ya the cascade 300, and just some small guppies. Another question, tomorrow im doing 100% water change, taking out the rocks, putting on the new filter, ect. How long should i let the water cycle before i put the fish back in?
EDIT: i think im also going to run the aqautech filter along with the cascade till the filter pads run out for it (i have 6 left it takes 2 at a time). Just letting you know for the cycle time
