Aqua- Tech #6 Cartridge 3 pack replacement filter cartridges for galaxy the Regent Galaxy 5 filtrat

I've had my AquaTech aqaurium for about 3 years now and all of the sudden Walmart no longer carries this particular replacement filter. Fortunately, I found them at Petsmart as Eclipse System 6 Replacement Cartridges.

So perhaps you can find them on here a little cheaper since they were like $7.00 there.
