What can I put instead of a fuge?

Hey Everybody,

I've always had problems in growing macro for some reason never notice a growth in them or anything don't know what I'm doing wrong. Well Ive been doing tons of research for my aunt on her soon to be freshwater tank (dark side)...if I was to take out all the sand and few bits of chaeto what kind of media or medias should I put in thier? I have a big fuge compartment so lots of space...

Imhey kev i used the 5000 watt bulb when display tank is off... Dont know why but i still get tons of algae, and also my bio load has increased and i feel like my fuge aint doing much for filteration in my tank IMO, which is why id rather just add another kind of filter media. Thanks

I'm thinking about taking everything out of the fuge... and add 5 gallons worth of pond matrix as I heard it has so much surface area for beneficial bacteria. I'm just trying to see if it will work in saltwater

How much waterflow do you think is enough? Also how can you tell?

Don't know if you know it but do you think I should put lets say an air wand underneath it? Like I would put like a little table of eggcrate and the pond matrix on it with air bubbles underneath

I'm running right a 72 gallon bowfront with a 33 gallon sump, I could grab dementions of water depth and such of the sump if needed.

Thanks
