Thanks for the input Fay.. Big fan of your tank by the way
No I'm gearing up for a native coldwater marine tank... have the tank and sump already but by "gearing up" I mean saving money and gathering other eqipment needed (skimmer, chiller, etc.)
So I will not be growing corals but instead use rocks collected in the sea for scaping. For substrate I was thinking sand but have read that it may not be a good idea? something about silica? will need to research further.
Anyway I want to do all filtration (bio) in the sump and I have bucket loads of ceramic bio noodles and was wondering if I could use those instead of getting dead coral.
Another question:
If I have all the media in the sump. Should the water run through it or should it be more of a huge pile that the water runs over?
Thanks
