Setting up 5 gallon pico reef today. It has about 8lbs live sand and 8lbs live rock. I used about 2 gallons of water from my established tank, and the rest is Catalina water. I'm not that impressed with the in tank filter. Not a lot of water flow. I know canister filters are not the best option. Although I was thinking of buying a canister filter removing all of the bio beads and just running chemi pure and some filter floss. Has anyone done this? Any thoughts or suggestions?
