It was nice being able to locate the exact individual parts to maintain my sponge filters. I have many tanks, and use two sponge filters per tank and things occasionally break or wear out. Shipping was cheap and this amazed me and I received everything in about 3 days. But the thing that really stood out about this shipment was the way they packed everything so carefully. Sponges were in compact, airtight bags to their selves, totally protected from the elements and the quality of the sponge itself is second to none. I definitely will be buying from these guys again.
