I am thinking about purchasing a Pool Sand Filter for my tank. Its rated for 5000 gallons of water and talks about keeping it mechanically clean down to 20 microns. Thats dandy and all but i need bio filtration. I have been told that The sand will only serve as mechanical, but i don't think that is true. After so many different answers i need to hear it from some one who uses a sand filter and can make sense of this. If the sand is moving and filtering out particles, it would still become a surface for BB correct? Sand has the highest SA and would provide a crazy amount of bio filtration. How are people not going to get amazing bio and mechanical? I am just trying to make sense of all this...
Also if i had the drum with the pump down below how would i get the pump started? Are most of the pumps able to suck in air and still pull water? Is there a specific pump i need to make sure is included to be able to prime and start the water itself? I am pretty sure my uncle has one for his pond because his pump has to pull air and water from above ground and his pond is below.
I know this probably has been posted but i haven't got all the answers i need. Thanks!
