Ceramic noodles

[Omega]

Hi guys and gals,

Will ceramic noodles work in a sump and not create a nitrate factory or does it have to be LR rubble?

Thanks

Any bio material can build up waste and create excess no3. Using lr in your tank/sump is the best option but with proper rinsing/maintenance in sw bio material can work as well. I’d add another 25+ lbs of lr/base rock in your 30 and you should be set for bio-filtration.

Will need to change my profile lol.

It is now a 30g main with a 30g sump and about 10p of LR sorry bout that.

Thanks for th info
