Aqua-Safe Group Order

[EmilyB]

Rich, everytime I go to their website there is no option for cartridges - can you give me a link ?

I'd actually like to be able to order individual cartridges, not the packs they send, does anyone know of an economical source for that perhaps?

I used to get most of my things from aquaticreefsystems but can't seem to get replies from them anymore.
